中文回答我
推荐一个完整的k3s集群部署方案
实现自动化部署
并且支持自建项目 git提交后就可以自动部署
围绕这个目标,
不运行你的开发能力,我要的是找到市场上已经有的最佳实践的git的开源项目,我们复制过来,填写必要的ip地址,然后运行起来
我关注的是配置的等幂性,而不是你对项目的开发

# 监控资源使用
watch kubectl top pods --all-namespaces
```
---
## 切换流量
### 1. 准备切换
```bash
# 降低DNS TTL提前24小时
# 在域名服务商控制台将TTL设置为300秒5分钟
# 准备回滚方案
# 记录旧集群IP准备快速回滚
```
### 2. 灰度切换(推荐)
```bash
# 使用权重DNS或负载均衡器
# 逐步增加新集群流量比例
# 30% -> 50% -> 70% -> 100%
# 监控新集群
watch kubectl top pods --all-namespaces
```
### 3. 完全切换
```bash
# 更新DNS记录
# 在域名服务商控制台修改A记录
# git.jpc.net3w.com A <NEW_MASTER_IP>
# argocd.jpc.net3w.com A <NEW_MASTER_IP>
# *.jpc.net3w.com A <NEW_MASTER_IP>
# 验证DNS生效
nslookup git.jpc.net3w.com
dig git.jpc.net3w.com
# 等待DNS传播5-30分钟
```
### 4. 切换后监控
```bash
# 监控应用状态
watch kubectl get pods --all-namespaces
# 监控日志
kubectl logs -n <namespace> -l app=<app-name> -f
# 检查错误
kubectl get events --all-namespaces --sort-by='.lastTimestamp'
```
---
## 故障回滚
### 1. 快速回滚DNS
```bash
# 如果新集群出现问题立即回滚DNS
# 在域名服务商控制台修改A记录回旧IP
# 清除本地DNS缓存
sudo systemd-resolve --flush-caches
# 验证回滚
nslookup git.jpc.net3w.com
```
### 2. 回滚应用
```bash
# 在旧集群重新启动应用
kubectl rollout restart deployment/<app-name> -n <namespace>
# 或在新集群回滚到旧版本
kubectl rollout undo deployment/<app-name> -n <namespace>
```
---
## 清理旧集群
### 1. 确认新集群稳定
```bash
# 运行至少7天确保
# - 所有功能正常
# - 性能满足要求
# - 没有数据丢失
# - 用户反馈良好
```
### 2. 最后备份旧集群
```bash
# 再次备份旧集群(以防万一)
ssh fei@<OLD_MASTER_IP>
sudo k3s etcd-snapshot save --name final-backup
sudo cp /var/lib/rancher/k3s/server/db/snapshots/final-backup* /backup/
```
### 3. 停止旧集群服务
```bash
# 在旧集群所有节点执行
# 停止K3s服务
sudo systemctl stop k3s
sudo systemctl stop k3s-agent
# 禁用自动启动
sudo systemctl disable k3s
sudo systemctl disable k3s-agent
```
### 4. 清理旧集群数据
```bash
# 在旧集群所有节点执行
# 卸载K3s
/usr/local/bin/k3s-uninstall.sh # master节点
/usr/local/bin/k3s-agent-uninstall.sh # worker节点
# 清理残留数据
sudo rm -rf /var/lib/rancher/k3s
sudo rm -rf /etc/rancher/k3s
```

# K3s集群部署幂等性测试指南
## 概述
本文档提供K3s集群部署幂等性的测试方法和验证标准。幂等性是指脚本可以重复执行多次每次都会产生相同的结果不会破坏现有配置或产生错误。
## 为什么需要幂等性?
在生产环境中,幂等性至关重要:
1. **可靠性**: 部署失败后可以安全地重试
2. **可维护性**: 配置更新可以通过重新运行脚本完成
3. **可移植性**: 重装系统后可以完全自动化重新部署
4. **一致性**: 确保多次部署产生相同的结果
## 幂等性测试方法
### 方法1: 自动化测试(推荐)
使用提供的测试脚本自动验证幂等性:
```bash
./scripts/test-idempotency.sh
```
**测试内容**:
1. 捕获初始集群状态
2. 重复执行部署脚本
3. 比较部署前后状态
4. 验证服务健康
5. 测试单个脚本幂等性
**预期结果**:
- 所有测试通过 ✓
- 部署前后状态一致(除了时间戳等元数据)
- 所有服务保持健康
### 方法2: 手动测试
#### 步骤1: 首次部署
```bash
# 记录开始时间
date
# 执行部署
./scripts/deploy-all.sh
# 验证部署
./scripts/verify-deployment.sh
# 记录集群状态
kubectl get all -A > /tmp/state-1.txt
kubectl get nodes -o yaml > /tmp/nodes-1.yaml
```
#### 步骤2: 重复部署
```bash
# 记录开始时间
date
# 再次执行部署
./scripts/deploy-all.sh
# 验证部署
./scripts/verify-deployment.sh
# 记录集群状态
kubectl get all -A > /tmp/state-2.txt
kubectl get nodes -o yaml > /tmp/nodes-2.yaml
```
#### 步骤3: 比较状态
```bash
# 比较资源列表(应该完全一致)
diff /tmp/state-1.txt /tmp/state-2.txt
# 比较节点状态(忽略时间戳)
diff <(grep -v "creationTimestamp\|resourceVersion\|uid" /tmp/nodes-1.yaml) \
<(grep -v "creationTimestamp\|resourceVersion\|uid" /tmp/nodes-2.yaml)
```
**预期结果**:
- 资源列表完全一致
- 节点状态一致(除了元数据)
- 无新增或删除的资源
### 方法3: 压力测试
连续多次执行部署脚本,验证稳定性:
```bash
# 连续执行5次
for i in {1..5}; do
echo "=== 第 $i 次执行 ==="
./scripts/deploy-all.sh
./scripts/verify-deployment.sh
echo ""
done
```
**预期结果**:
- 所有执行都成功
- 无错误或警告
- 服务始终保持健康
## 幂等性验证清单
### 基础验证
- [ ] 脚本可以重复执行而不报错
- [ ] 重复执行不会创建重复资源
- [ ] 重复执行不会删除现有资源
- [ ] 重复执行不会修改不应该修改的配置
### K3s集群验证
- [ ] 节点数量保持不变
- [ ] 节点状态保持Ready
- [ ] 系统Pod数量和状态不变
- [ ] kubectl配置保持有效
### Gitea验证
- [ ] Gitea命名空间存在
- [ ] Gitea部署状态不变
- [ ] Gitea Pod数量和状态不变
- [ ] Gitea服务配置不变
- [ ] Gitea组织和仓库保持不变
- [ ] Gitea用户和权限保持不变
### ArgoCD验证
- [ ] ArgoCD命名空间存在
- [ ] ArgoCD所有组件运行正常
- [ ] ArgoCD admin密码保持不变
- [ ] ArgoCD Application配置不变
- [ ] ArgoCD与Gitea连接正常
### HTTPS证书验证
- [ ] cert-manager正常运行
- [ ] ClusterIssuer状态Ready
- [ ] Certificate状态Ready
- [ ] Ingress配置正确
- [ ] HTTPS访问正常
### 存储验证
- [ ] PV数量和状态不变
- [ ] PVC数量和状态不变
- [ ] 数据未丢失
## 常见幂等性问题及解决方案
### 问题1: 重复创建资源导致冲突
**症状**:
```
Error: resource already exists
```
**解决方案**:
- 使用 `kubectl apply` 而不是 `kubectl create`
- 使用 `--dry-run=client -o yaml | kubectl apply -f -`
- 添加资源存在性检查
**示例**:
```bash
# 错误方式
kubectl create namespace argocd
# 正确方式
kubectl create namespace argocd --dry-run=client -o yaml | kubectl apply -f -
```
### 问题2: 工具重复安装
**症状**:
```
Package already installed
```
**解决方案**:
- 安装前检查工具是否已存在
- 使用 `command -v` 检查命令可用性
**示例**:
```bash
# 检查后安装
if ! command -v yq &> /dev/null; then
sudo wget -qO /usr/local/bin/yq https://...
fi
```
### 问题3: 配置覆盖导致数据丢失
**症状**:
- 密码被重置
- 配置被覆盖
- 数据丢失
**解决方案**:
- 使用 `kubectl patch` 而不是完全替换
- 检查资源是否已存在
- 使用 `--dry-run` 预览变更
**示例**:
```bash
# 使用patch更新密码
kubectl -n argocd patch secret argocd-secret \
-p '{"stringData": {"admin.password": "..."}}'
```
### 问题4: 网络下载失败
**症状**:
```
Failed to download: Connection timeout
```
**解决方案**:
- 添加重试机制
- 使用本地缓存
- 提供离线安装选项
**示例**:
```bash
# 重试下载
for attempt in 1 2 3; do
if curl -fsSL "$URL" -o "$OUTPUT"; then
break
fi
sleep 5
done
```
### 问题5: 状态检查不完善
**症状**:
- 后续步骤因前置条件不满足而失败
- 资源未就绪就继续执行
**解决方案**:
- 使用 `kubectl wait` 等待资源就绪
- 添加健康检查
- 设置合理的超时时间
**示例**:
```bash
# 等待部署就绪
kubectl wait --for=condition=available \
--timeout=600s \
deployment/argocd-server -n argocd
```
## 幂等性最佳实践
### 1. 使用声明式API
```bash
# 推荐: 声明式
kubectl apply -f manifest.yaml
# 不推荐: 命令式
kubectl create -f manifest.yaml
```
### 2. 检查资源存在性
```bash
# 检查命名空间
if kubectl get namespace argocd &>/dev/null; then
echo "Namespace already exists"
else
kubectl create namespace argocd
fi
```
### 3. 使用幂等的包管理器
```bash
# Helm自动处理幂等性
helm upgrade --install gitea gitea-charts/gitea \
--namespace gitea \
--values values.yaml
```
### 4. 记录部署状态
```bash
# 记录已完成的步骤
mark_step_completed() {
echo "$1" >> .deployment-state
}
# 检查步骤是否已完成
is_step_completed() {
grep -q "^$1$" .deployment-state 2>/dev/null
}
```
### 5. 添加重试机制
```bash
# 通用重试函数
retry() {
local max_attempts=$1
local delay=$2
shift 2
local cmd="$@"
for attempt in $(seq 1 $max_attempts); do
if eval "$cmd"; then
return 0
fi
sleep $delay
done
return 1
}
```
### 6. 详细的日志记录
```bash
# 记录所有操作
log() {
echo "[$(date '+%Y-%m-%d %H:%M:%S')] $1" | tee -a deployment.log
}
```
## 测试场景

# 5. 在ArgoCD中创建Application
# 访问 https://argocd.jpd.net3w.com
```
---
## 常见问题
### Q1: DNS解析不生效怎么办
**A**: DNS传播需要时间5-30分钟。可以先使用NodePort访问
```bash
# 获取服务NodePort
kubectl get svc -n gitea
kubectl get svc -n argocd
# 通过IP:Port访问
http://149.13.91.216:<NodePort>
```
### Q2: Pod一直处于Pending状态
**A**: 检查节点资源和Pod事件
```bash
# 查看节点资源
kubectl top nodes
# 查看Pod详情
kubectl describe pod <pod-name> -n <namespace>
# 查看事件
kubectl get events -n <namespace> --sort-by='.lastTimestamp'
```
### Q3: 证书未签发?
**A**: 检查cert-manager和DNS配置
```bash
# 查看cert-manager日志
kubectl logs -n cert-manager -l app=cert-manager --tail=50
# 查看证书请求
kubectl get certificaterequest --all-namespaces
# 查看证书详情
kubectl describe certificate <cert-name> -n <namespace>
```
### Q4: 如何切换回JPC集群
**A**: 切换kubeconfig
```bash
# 切换到JPC集群
export KUBECONFIG=~/.kube/config
# 或者切换到JPD集群
export KUBECONFIG=~/.kube/config-jpd
# 验证当前集群
kubectl cluster-info
kubectl get nodes
```
### Q5: 如何同时管理多个集群?
**A**: 使用kubectl context
```bash
# 合并kubeconfig
KUBECONFIG=~/.kube/config:~/.kube/config-jpd kubectl config view --flatten > ~/.kube/config-merged
cp ~/.kube/config-merged ~/.kube/config
# 查看所有context
kubectl config get-contexts
# 切换context
kubectl config use-context <context-name>
# 查看当前context
kubectl config current-context
```

```bash
# 创建项目根目录
mkdir -p ~/my-app
cd ~/my-app
# 创建manifests目录存放Kubernetes配置文件
mkdir -p manifests
# 创建项目结构
tree
# my-app/
# └── manifests/
```
### 步骤2: 创建README文件
```bash
cat > README.md <<'EOF'
# My Application
这是一个由ArgoCD管理的应用使用GitOps自动化部署。
## 应用信息
- **应用名称**: my-app
- **域名**: myapp.jpc.net3w.com
- **命名空间**: default

curl https://myapp.jpc.net3w.com
```
## 更新应用
修改 `manifests/` 目录下的文件并提交到GitArgoCD会自动同步部署。
## 监控部署
```bash
# 查看Pod状态
kubectl get pods -l app=my-app -n default
# 查看ArgoCD Application
kubectl get application my-app -n argocd
```
EOF
```
---
## 编写Kubernetes Manifests
### 步骤3: 创建Deployment配置
```bash
cat > manifests/deployment.yaml <<'EOF'
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-app
namespace: default
labels:
app: my-app
spec:
replicas: 2
selector:
matchLabels:
app: my-app
template:
metadata:
labels:
app: my-app
spec:
containers:
- name: app
image: nginx:1.25-alpine # 替换为你的镜像
ports:
- containerPort: 80
name: http
resources:
requests:
memory: "64Mi"
cpu: "100m"
limits:
memory: "128Mi"
cpu: "200m"
livenessProbe:
httpGet:
path: /
port: 80
initialDelaySeconds: 10
periodSeconds: 10
readinessProbe:
httpGet:
path: /
port: 80
initialDelaySeconds: 5
periodSeconds: 5
EOF
```
**配置说明**:
- `replicas: 2` - 运行2个Pod副本
- `image` - 容器镜像,根据实际情况修改
- `resources` - 资源限制,防止资源耗尽
- `livenessProbe` - 存活探针Pod不健康时自动重启
- `readinessProbe` - 就绪探针Pod未就绪时不接收流量
### 步骤4: 创建Service配置
```bash
cat > manifests/service.yaml <<'EOF'
apiVersion: v1
kind: Service
metadata:
name: my-app
namespace: default
labels:
app: my-app
spec:
type: ClusterIP
selector:
app: my-app
ports:
- port: 80
targetPort: 80
protocol: TCP
name: http
EOF
```
**配置说明**:
- `type: ClusterIP` - 集群内部访问
- `selector` - 选择带有 `app=my-app` 标签的Pod
- `port: 80` - Service端口
### 步骤5: 创建Ingress配置
```bash
cat > manifests/ingress.yaml <<'EOF'
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: my-app
namespace: default
annotations:
cert-manager.io/cluster-issuer: "letsencrypt-prod"
traefik.ingress.kubernetes.io/router.entrypoints: websecure
spec:
ingressClassName: traefik # 使用traefik根据集群实际情况修改
tls:
- hosts:
- myapp.jpc.net3w.com # 替换为你的域名
secretName: my-app-tls
rules:
- host: myapp.jpc.net3w.com # 替换为你的域名
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: my-app
port:
number: 80
EOF
```
**配置说明**:
- `ingressClassName` - 使用的Ingress控制器traefik或nginx
- `cert-manager.io/cluster-issuer` - 自动签发HTTPS证书
- `tls` - HTTPS配置
- `rules` - 路由规则将域名流量转发到Service
### 步骤6: 创建ConfigMap可选
如果需要自定义配置文件或HTML内容
```bash
cat > manifests/configmap.yaml <<'EOF'
apiVersion: v1
kind: ConfigMap
metadata:
name: my-app-config
namespace: default
data:
# 配置文件内容
app.conf: |
server {
listen 80;
server_name myapp.jpc.net3w.com;
location / {
root /usr/share/nginx/html;
index index.html;
}
}
# HTML内容
index.html: |
<!DOCTYPE html>
<html>
<head>
<title>My Application</title>
</head>
<body>
<h1>Welcome to My Application</h1>
<p>Version: v1.0</p>
</body>
</html>
EOF
```
如果使用ConfigMap需要在Deployment中挂载
```yaml
# 在deployment.yaml的containers部分添加
volumeMounts:
- name: config
mountPath: /etc/nginx/conf.d/app.conf
subPath: app.conf
- name: html
mountPath: /usr/share/nginx/html
# 在spec部分添加
volumes:
- name: config
configMap:
name: my-app-config
- name: html
configMap:
name: my-app-config
```
---
## 本地测试验证
### 步骤7: 验证YAML语法
```bash
# 验证所有manifest文件的语法
kubectl apply --dry-run=client -f manifests/
# 应该看到类似输出:
# deployment.apps/my-app created (dry run)
# service/my-app created (dry run)
# ingress.networking.k8s.io/my-app created (dry run)
```
### 步骤8: 本地部署测试
```bash
# 部署到集群
kubectl apply -f manifests/
# 查看部署状态
kubectl get pods -l app=my-app -n default
kubectl get svc my-app -n default
kubectl get ingress my-app -n default
# 查看Pod日志
kubectl logs -l app=my-app -n default --tail=50
# 查看Pod详情如果有问题
kubectl describe pod -l app=my-app -n default
```
### 步骤9: 测试访问
```bash
# 方式1: 通过Service ClusterIP测试集群内部
kubectl run test-pod --rm -it --image=curlimages/curl -- sh
# 在Pod内执行: curl http://my-app.default.svc.cluster.local
# 方式2: 通过域名测试
curl http://myapp.jpc.net3w.com
curl https://myapp.jpc.net3w.com
# 方式3: 通过Host header测试
NODE_IP=$(kubectl get nodes -o jsonpath='{.items[0].status.addresses[0].address}')
curl -H "Host: myapp.jpc.net3w.com" http://$NODE_IP
```
### 步骤10: 验证成功后清理
```bash
# 测试成功后,删除手动部署的资源
# 稍后会通过ArgoCD重新部署
kubectl delete -f manifests/
```
---
## 上传到Gitea
### 步骤11: 在Gitea中创建仓库
**方式1: 通过Web界面创建**
1. 访问Gitea: `http://<NODE_IP>:<GITEA_PORT>`
2. 使用管理员账户登录gitea_admin / GitAdmin@2026
3. 点击右上角 "+" → "新建仓库"
4. 填写信息:
- 所有者: `k3s-apps`(组织)
- 仓库名称: `my-app`
- 描述: `My application for GitOps demo`
- 可见性: 公开
- 不要勾选"使用README初始化"
5. 点击"创建仓库"
**方式2: 通过API创建**
```bash
# 获取Gitea信息
GITEA_PORT=$(kubectl get svc gitea-http -n gitea -o jsonpath='{.spec.ports[0].nodePort}')
NODE_IP=8.216.38.248 # 替换为你的节点IP
GITEA_URL="http://$NODE_IP:$GITEA_PORT"
# 创建仓库
curl -X POST \
-u "gitea_admin:GitAdmin@2026" \
-H "Content-Type: application/json" \
-d '{"name":"my-app","description":"My application for GitOps demo","private":false,"auto_init":false}' \
"$GITEA_URL/api/v1/org/k3s-apps/repos"
# 验证仓库已创建
curl -s -u "gitea_admin:GitAdmin@2026" "$GITEA_URL/api/v1/orgs/k3s-apps/repos" | jq -r '.[].name'
```
### 步骤12: 初始化Git仓库
```bash
cd ~/my-app
# 初始化Git仓库
git init -b main
# 配置Git用户信息
git config user.name "gitea_admin"
git config user.email "admin@jpc.net3w.com"
# 添加所有文件
git add .
# 查看将要提交的文件
git status
# 提交
git commit -m "Initial commit: Add my-app manifests
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"
```
### 步骤13: 推送到Gitea
```bash
# 添加远程仓库
GITEA_PORT=$(kubectl get svc gitea-http -n gitea -o jsonpath='{.spec.ports[0].nodePort}')
NODE_IP=8.216.38.248 # 替换为你的节点IP
REPO_URL="http://$NODE_IP:$GITEA_PORT/k3s-apps/my-app.git"
git remote add origin "$REPO_URL"
# 推送(使用管理员账户)
git remote set-url origin "http://gitea_admin:GitAdmin%402026@$NODE_IP:$GITEA_PORT/k3s-apps/my-app.git"
git push -u origin main
# 验证推送成功
echo "访问Gitea查看仓库: $REPO_URL"
```
**常见问题**:
- **503错误**: Gitea服务可能正在启动等待几秒后重试
- **403错误**: 检查用户名密码是否正确
- **认证失败**: 确保密码中的特殊字符已URL编码@编码为%40
---
## 配置ArgoCD自动部署
### 步骤14: 创建ArgoCD Application
```bash
# 创建Application配置文件
cat > /tmp/my-app-argocd.yaml <<EOF
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: my-app
namespace: argocd
labels:
app: my-app
spec:
project: default
source:
repoURL: http://gitea-http.gitea.svc.cluster.local:3000/k3s-apps/my-app.git
targetRevision: main
path: manifests
destination:
server: https://kubernetes.default.svc
namespace: default
syncPolicy:
automated:
prune: true # 自动删除Git中不存在的资源
selfHeal: true # 自动修复手动修改的资源
syncOptions:
- CreateNamespace=true
EOF
# 应用配置
kubectl apply -f /tmp/my-app-argocd.yaml
# 查看Application状态
kubectl get application my-app -n argocd
```
**配置说明**:
- `repoURL` - Git仓库地址使用集群内部地址
- `targetRevision: main` - 监控main分支
- `path: manifests` - manifests目录
- `automated` - 启用自动同步
- `prune: true` - 自动删除不需要的资源
- `selfHeal: true` - 自动修复被手动修改的资源
### 步骤15: 配置Git仓库凭证如果是私有仓库
```bash
# 创建Git凭证Secret
kubectl create secret generic gitea-creds \
-n argocd \
--from-literal=username="argocd" \
--from-literal=password="ArgoCD@2026" \
--dry-run=client -o yaml | kubectl apply -f -
```
### 步骤16: 手动触发首次同步
```bash
# 触发同步
kubectl patch application my-app -n argocd \
--type merge \
-p '{"operation":{"initiatedBy":{"username":"admin"},"sync":{"revision":"HEAD"}}}'
# 或者使用ArgoCD CLI如果已安装
argocd app sync my-app
```
---
## 验证和监控
### 步骤17: 监控同步状态
```bash
# 实时监控Application状态
watch kubectl get application my-app -n argocd
# 查看详细状态
kubectl describe application my-app -n argocd
# 查看同步历史
kubectl get application my-app -n argocd -o jsonpath='{.status.operationState}'
```
**状态说明**:
- `Sync Status: Synced` - 已同步
- `Health Status: Healthy` - 健康
- `Sync Status: OutOfSync` - 未同步Git有更新
- `Sync Status: Unknown` - 未知(可能有错误)
### 步骤18: 查看部署的资源
```bash
# 查看所有资源
kubectl get all -l app=my-app -n default
# 查看Pod
kubectl get pods -l app=my-app -n default -o wide
# 查看Service
kubectl get svc my-app -n default
# 查看Ingress
kubectl get ingress my-app -n default
# 查看证书状态
kubectl get certificate -n default | grep my-app
```
### 步骤19: 测试应用访问
```bash
# HTTP访问
curl http://myapp.jpc.net3w.com
# HTTPS访问
curl https://myapp.jpc.net3w.com
# 查看响应头
curl -I https://myapp.jpc.net3w.com
# 浏览器访问
echo "在浏览器中访问: https://myapp.jpc.net3w.com"
```
### 步骤20: 查看ArgoCD UI
```bash
# 获取ArgoCD访问地址
echo "ArgoCD UI: https://argocd.jpc.net3w.com"
# 获取admin密码如果忘记
kubectl -n argocd get secret argocd-initial-admin-secret \
-o jsonpath="{.data.password}" | base64 -d && echo
```
在ArgoCD UI中可以看到
- 应用的同步状态
- 资源拓扑图
- 同步历史
- 事件日志
---
## 更新应用
### 方式1: 修改Git仓库
```bash
cd ~/my-app
# 修改配置(例如:增加副本数)
sed -i 's/replicas: 2/replicas: 3/' manifests/deployment.yaml
# 查看修改
git diff
# 提交更改
git add manifests/deployment.yaml
git commit -m "Scale up to 3 replicas"
git push
# ArgoCD会在3分钟内自动检测并同步
```
### 方式2: 创建更新脚本
```bash
cat > update-app.sh <<'EOF'
#!/bin/bash
set -e
VERSION=${1:-v2.0}
echo "🔄 更新应用到版本 $VERSION"
# 修改版本号(根据实际情况修改)
sed -i "s/Version: v[0-9.]*/Version: $VERSION/" manifests/configmap.yaml
# 提交更改
git add .
git commit -m "Update to $VERSION
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"
git push
echo "✅ 更新完成!"
echo "⏳ 等待ArgoCD同步约3分钟..."
EOF
chmod +x update-app.sh
# 使用脚本更新
./update-app.sh v2.0
```
### 方式3: 通过ArgoCD UI手动同步
1. 访问ArgoCD UI
2. 找到你的应用
3. 点击"SYNC"按钮
4. 选择同步选项
5. 点击"SYNCHRONIZE"
### 监控更新进度
```bash
# 监控Pod更新
watch kubectl get pods -l app=my-app -n default
# 查看滚动更新状态
kubectl rollout status deployment/my-app -n default
# 查看更新历史
kubectl rollout history deployment/my-app -n default
```
---
## 故障排查
### 常见问题1: Pod无法启动
```bash
# 查看Pod状态
kubectl get pods -l app=my-app -n default
# 查看Pod详情
kubectl describe pod -l app=my-app -n default
# 查看Pod日志
kubectl logs -l app=my-app -n default --tail=100
# 查看事件
kubectl get events -n default --sort-by='.lastTimestamp' | grep my-app
```
**可能原因**:
- 镜像拉取失败
- 资源不足
- 配置错误
- 健康检查失败
### 常见问题2: Ingress无法访问
```bash
# 检查Ingress配置
kubectl describe ingress my-app -n default
# 检查IngressClass
kubectl get ingressclass
# 测试Service是否正常
kubectl run test-pod --rm -it --image=curlimages/curl -- \
curl http://my-app.default.svc.cluster.local
# 检查DNS解析
nslookup myapp.jpc.net3w.com
```
**可能原因**:
- IngressClass配置错误应该是traefik
- DNS未解析到正确IP
- 证书未签发
- Service配置错误
### 常见问题3: ArgoCD不同步
```bash
# 查看Application状态
kubectl describe application my-app -n argocd
# 查看ArgoCD repo-server日志
kubectl logs -n argocd -l app.kubernetes.io/name=argocd-repo-server --tail=50
# 清除ArgoCD缓存
kubectl exec -n argocd deployment/argocd-repo-server -- \
sh -c "rm -rf /tmp/_argocd-repo/*"
# 重启repo-server
kubectl delete pod -n argocd -l app.kubernetes.io/name=argocd-repo-server
# 手动触发同步
kubectl patch application my-app -n argocd \
--type merge \
-p '{"operation":{"initiatedBy":{"username":"admin"},"sync":{"revision":"HEAD"}}}'
```
**可能原因**:
- Git仓库访问失败
- YAML语法错误
- ArgoCD缓存问题
- 网络问题
### 常见问题4: 证书未签发
```bash
# 查看证书状态
kubectl get certificate -n default
# 查看证书详情
kubectl describe certificate my-app-tls -n default
# 查看cert-manager日志
kubectl logs -n cert-manager -l app=cert-manager --tail=50
# 查看证书请求
kubectl get certificaterequest -n default
```
**可能原因**:
- cert-manager未正确配置
- DNS验证失败
- Let's Encrypt速率限制
- Ingress注解错误
---
## 回滚操作
### 通过Git回滚
```bash
cd ~/my-app
# 查看提交历史
git log --oneline
# 回滚到指定commit
git revert <commit-hash>
git push
# ArgoCD会自动同步回滚
```
### 通过kubectl回滚
```bash
# 查看部署历史
kubectl rollout history deployment/my-app -n default
# 回滚到上一个版本
kubectl rollout undo deployment/my-app -n default
# 回滚到指定版本
kubectl rollout undo deployment/my-app -n default --to-revision=2
```
### 通过ArgoCD回滚
```bash
# 查看历史版本
argocd app history my-app
# 回滚到指定版本
argocd app rollback my-app <revision-id>
```
---
## 清理资源
### 删除应用
```bash
# 删除ArgoCD Application会自动删除K8s资源
kubectl delete application my-app -n argocd
# 或者手动删除资源
kubectl delete -f manifests/
```
### 删除Git仓库
```bash
# 通过API删除
GITEA_PORT=$(kubectl get svc gitea-http -n gitea -o jsonpath='{.spec.ports[0].nodePort}')
NODE_IP=8.216.38.248
curl -X DELETE \
-u "gitea_admin:GitAdmin@2026" \
"http://$NODE_IP:$GITEA_PORT/api/v1/repos/k3s-apps/my-app"
```
---
## 最佳实践
### 1. 项目结构
```
my-app/
├── README.md # 项目说明
├── manifests/ # Kubernetes配置
│ ├── deployment.yaml
│ ├── service.yaml
│ ├── ingress.yaml
│ └── configmap.yaml
├── update-app.sh # 更新脚本
└── .gitignore # Git忽略文件
```
### 2. 命名规范
- **应用名称**: 使用小写字母和连字符,如 `my-app`
- **标签**: 统一使用 `app=my-app`
- **命名空间**: 根据环境划分,如 `default`, `staging`, `production`
### 3. 资源配置
- **副本数**: 至少2个保证高可用
- **资源限制**: 必须设置requests和limits
- **健康检查**: 配置liveness和readiness探针
- **镜像标签**: 使用具体版本号避免使用latest
### 4. Git提交规范
```bash
# 好的提交信息
git commit -m "Add health check endpoint"
git commit -m "Scale up to 3 replicas"
git commit -m "Update to version 2.0"
# 不好的提交信息
git commit -m "update"
git commit -m "fix"
```
### 5. 安全建议
- 使用私有仓库存储敏感配置
- 使用Kubernetes Secrets存储密码
- 定期更新镜像版本
- 启用HTTPS和证书自动续期
- 配置网络策略限制Pod通信
### 6. 监控和日志
```bash
# 配置日志收集
kubectl logs -l app=my-app -n default --tail=100 -f
# 配置监控告警
# 使用Prometheus + Grafana监控应用指标
# 配置资源监控
kubectl top pods -l app=my-app -n default
```
---
## 快速参考
### 常用命令
```bash
# 查看应用状态
kubectl get all -l app=my-app -n default
# 查看ArgoCD Application
kubectl get application my-app -n argocd
# 查看日志
kubectl logs -l app=my-app -n default --tail=50 -f
# 进入Pod调试
kubectl exec -it <pod-name> -n default -- sh
# 查看资源使用
kubectl top pods -l app=my-app -n default
# 手动触发同步
kubectl patch application my-app -n argocd \
--type merge \
-p '{"operation":{"initiatedBy":{"username":"admin"},"sync":{"revision":"HEAD"}}}'
```
### 配置文件模板
所有配置文件模板可以在 `templates/` 目录找到,或参考现有项目:
- nginx-app: http://8.216.38.248:32158/k3s-apps/nginx-app
- test-app: http://8.216.38.248:32158/k3s-apps/test-app
- demo-app: http://8.216.38.248:32158/k3s-apps/demo-app

# Nginx测试应用 - 自动化部署指南
## 概述
这是一个基于GitOps模式的Nginx测试应用用于演示K3s集群的自动化部署流程。
## 应用信息
- **应用名称**: nginx-test
- **域名**: ng.jpc.net3w.com
- **镜像**: nginx:1.25-alpine
- **副本数**: 2
- **部署方式**: GitOps (Gitea + ArgoCD)
## 快速部署
### 一键部署
```bash
./scripts/deploy-nginx-app.sh
```
这个脚本会自动完成以下步骤:
1. 检查依赖和集群状态
2. 在Gitea中创建nginx-app仓库
3. 推送应用manifests到Git仓库
4. 在ArgoCD中创建Application
5. 等待自动同步完成
### 分步部署
如果需要分步执行,可以运行:
```bash
# 步骤1: 推送应用到Gitea
./scripts/push-nginx-app.sh
# 步骤2: 创建ArgoCD Application
./scripts/create-nginx-argocd-app.sh
```
## 访问应用
### 通过域名访问(推荐)
```bash
# HTTP访问会自动重定向到HTTPS
curl http://ng.jpc.net3w.com
# HTTPS访问
curl https://ng.jpc.net3w.com
# 浏览器访问
https://ng.jpc.net3w.com
```
### 通过NodePort访问
```bash
# 获取Service信息
kubectl get svc nginx-test -n default
# 访问应用
NODE_IP=$(kubectl get nodes -o jsonpath='{.items[0].status.addresses[0].address}')
NODE_PORT=$(kubectl get svc nginx-test -n default -o jsonpath='{.spec.ports[0].nodePort}')
curl http://$NODE_IP:$NODE_PORT
```
## 验证部署
```bash
# 查看Pod状态
kubectl get pods -l app=nginx-test -n default
# 查看Service
kubectl get svc nginx-test -n default
# 查看Ingress
kubectl get ingress nginx-test -n default
# 查看ArgoCD Application状态
kubectl get application nginx-app -n argocd
# 查看详细信息
kubectl describe application nginx-app -n argocd
```
## 更新应用
### 方式1: 使用更新脚本(推荐)
SSH到master节点运行更新脚本
```bash
# SSH到master节点
ssh fei@8.216.38.248
# 进入应用目录
cd /home/fei/k3s/nginx-app
# 更新到v2.0版本
./update-app.sh v2.0
# 更新到v3.0版本
./update-app.sh v3.0
```
### 方式2: 手动修改Git仓库
1. 克隆仓库:
```bash
git clone http://<NODE_IP>:<GITEA_PORT>/k3s-apps/nginx-app.git
cd nginx-app
```
2. 修改配置文件:
```bash
# 修改版本号
vim manifests/configmap.yaml
# 将 "Version: v1.0" 改为 "Version: v2.0"
# 或修改副本数
vim manifests/deployment.yaml
# 将 replicas: 2 改为 replicas: 3
```
3. 提交并推送:
```bash
git add .
git commit -m "Update to v2.0"
git push
```
4. 等待ArgoCD自动同步约3分钟
### 方式3: 通过ArgoCD UI手动同步
1. 访问ArgoCD: https://argocd.jpc.net3w.com
2. 找到nginx-app应用
3. 点击"SYNC"按钮立即同步
## 监控同步状态
```bash
# 实时监控ArgoCD同步状态
watch kubectl get application nginx-app -n argocd
# 查看Pod更新状态
watch kubectl get pods -l app=nginx-test -n default
# 查看应用日志
kubectl logs -l app=nginx-test -n default --tail=50 -f
```
## GitOps工作流
```
开发者修改代码
提交到Git仓库 (Gitea)
ArgoCD检测到变化 (每3分钟轮询)
ArgoCD自动同步
K3s集群自动部署
应用更新完成
```

DNS (ng.jpc.net3w.com)
Nginx Ingress Controller
Service (nginx-test)
Pods (nginx-test)
```
## 配置文件说明
### 1. Deployment (manifests/deployment.yaml)
定义应用的部署配置:
- 副本数: 2
- 镜像: nginx:1.25-alpine
- 资源限制: CPU 100m-200m, Memory 64Mi-128Mi
- 健康检查: liveness和readiness探针

定义服务访问方式:
- 类型: ClusterIP
- 端口: 80
### 3. Ingress (manifests/ingress.yaml)
定义外部访问规则:
- 域名: ng.jpc.net3w.com
- TLS: 自动签发Let's Encrypt证书
- 自动HTTPS重定向
### 4. ConfigMap (manifests/configmap.yaml)
包含两个ConfigMap
- nginx-config: Nginx配置文件
- nginx-html: 自定义HTML页面
## 故障排查
### 问题1: 无法访问域名
```bash
# 检查DNS解析
nslookup ng.jpc.net3w.com
# 检查Ingress状态
kubectl describe ingress nginx-test -n default
# 检查证书状态
kubectl get certificate -n default
```
### 问题2: Pod无法启动
```bash
# 查看Pod详情
kubectl describe pod -l app=nginx-test -n default
# 查看Pod日志
kubectl logs -l app=nginx-test -n default
# 查看事件
kubectl get events -n default --sort-by='.lastTimestamp'
```
### 问题3: ArgoCD不同步
```bash
# 查看Application状态
kubectl describe application nginx-app -n argocd
# 手动触发同步
kubectl patch application nginx-app -n argocd \
--type merge -p '{"operation":{"initiatedBy":{"username":"admin"},"sync":{"revision":"HEAD"}}}'
# 或通过ArgoCD CLI
argocd app sync nginx-app
```
### 问题4: 证书未签发
```bash
# 查看证书请求
kubectl get certificaterequest -n default
# 查看cert-manager日志
kubectl logs -n cert-manager -l app=cert-manager
# 手动删除并重新创建证书
kubectl delete certificate nginx-test-tls -n default
kubectl delete secret nginx-test-tls -n default
```
## 回滚操作
### 通过Git回滚
```bash
# 查看提交历史
git log --oneline
# 回滚到指定版本
git revert <commit-hash>
git push
# ArgoCD会自动同步回滚
```
### 通过ArgoCD回滚
```bash
# 查看历史版本
argocd app history nginx-app
# 回滚到指定版本
argocd app rollback nginx-app <revision-id>
```
## 清理资源
```bash
# 删除ArgoCD Application会自动删除K8s资源
kubectl delete application nginx-app -n argocd
# 删除Gitea仓库通过API
GITEA_USER="argocd"
GITEA_PASSWORD="ArgoCD@2026"
NODE_IP=$(kubectl get nodes -o jsonpath='{.items[0].status.addresses[0].address}')
GITEA_PORT=$(kubectl get svc gitea-http -n gitea -o jsonpath='{.spec.ports[0].nodePort}')
curl -X DELETE \
-u "$GITEA_USER:$GITEA_PASSWORD" \
"http://$NODE_IP:$GITEA_PORT/api/v1/repos/k3s-apps/nginx-app"
```

- ✅ K3s集群状态节点、系统Pod
- ✅ Gitea服务部署、Pod、访问地址
- ✅ ArgoCD服务Server、Controller、Repo Server
- ✅ HTTPS证书cert-manager、ClusterIssuer、Certificate
- ✅ GitOps工作流ArgoCD Application状态
- ✅ 存储卷状态PV、PVC
### 手动验证
#### 验证K3s集群
```bash
# 查看节点状态
kubectl get nodes
# 查看所有Pod
kubectl get pods -A
# 创建测试Pod
kubectl run test --image=nginx
```
### 验证Gitea
```bash
# 查看Gitea Pod状态
kubectl get pods -n gitea
# 查看Gitea服务
kubectl get svc -n gitea
# 获取Gitea访问地址
GITEA_NODEPORT=$(kubectl get svc gitea-http -n gitea -o jsonpath='{.spec.ports[0].nodePort}')
echo "Gitea访问地址: http://8.216.38.248:$GITEA_NODEPORT"
```
### 验证ArgoCD
```bash
# 查看ArgoCD Pod状态
kubectl get pods -n argocd
# 查看ArgoCD服务
kubectl get svc -n argocd
# 获取ArgoCD访问地址
ARGOCD_NODEPORT=$(kubectl get svc argocd-server -n argocd -o jsonpath='{.spec.ports[0].nodePort}')
echo "ArgoCD访问地址: https://8.216.38.248:$ARGOCD_NODEPORT"
echo "用户名: admin"
echo "密码: ArgoAdmin@2026"
# 查看Application状态
kubectl get application -n argocd
```
### 验证GitOps
```bash
# 查看应用同步状态
kubectl describe application demo-app -n argocd
# 查看示例应用
kubectl get pods -n default
kubectl get svc demo-nginx -n default
# 访问示例应用
curl http://8.216.38.248:30080
# 测试自动同步修改Gitea仓库内容等待3分钟观察自动部署
```
## 安全建议
### 1. 使用Ansible Vault加密配置
```bash
# 加密配置文件
ansible-vault encrypt config/cluster-vars.yml
# 编辑加密文件
ansible-vault edit config/cluster-vars.yml
# 部署时使用加密文件
cd k3s-ansible
ansible-playbook site.yml -i inventory/hosts.ini -e "@../config/cluster-vars.yml" --ask-vault-pass
```
### 2. 限制文件权限
```bash
chmod 600 config/cluster-vars.yml
```
### 3. 不要提交敏感信息到Git
`.gitignore`已配置忽略敏感文件:
- `config/cluster-vars.yml`
- `config/*-vars.yml`
- `*.vault`
## 故障排查
### K3s部署失败
```bash
# 测试SSH连接
ansible all -i k3s-ansible/inventory/hosts.ini -m ping
# 查看详细日志
cd k3s-ansible
ansible-playbook site.yml -i inventory/hosts.ini -e "@../config/cluster-vars.yml" -vvv
```
### Gitea无法访问
```bash
# 检查Pod状态
kubectl get pods -n gitea
# 查看日志
kubectl logs -n gitea -l app.kubernetes.io/name=gitea
# 检查Service
kubectl get svc -n gitea
# 检查持久化存储
kubectl get pvc -n gitea
```
### ArgoCD无法访问
```bash
# 检查Pod状态
kubectl get pods -n argocd
# 查看日志
kubectl logs -n argocd deployment/argocd-server
# 检查Service
kubectl get svc -n argocd
```
### GitOps同步失败
```bash
# 查看Application详情
kubectl describe application demo-app -n argocd
# 查看ArgoCD控制器日志
kubectl logs -n argocd deployment/argocd-application-controller
# 测试ArgoCD到Gitea的连接
kubectl exec -n argocd deployment/argocd-server -- curl -v http://gitea-http.gitea.svc.cluster.local:3000
# 检查Gitea仓库凭证
kubectl get secret gitea-creds -n argocd -o yaml
```
## 幂等性保证
### 什么是幂等性?
幂等性意味着脚本可以重复执行多次,每次都会产生相同的结果,不会破坏现有配置或产生错误。
### 本项目的幂等性实现
#### 1. 统一部署脚本 (`deploy-all.sh`)
-**状态持久化**: 记录已完成的步骤到 `.deployment-state` 文件
-**断点续传**: 失败后重新运行会跳过已完成的步骤
-**重复执行安全**: 已完成的步骤会被自动跳过
#### 2. 工具依赖检查
-**自动检测**: 检查工具是否已安装
-**自动安装**: 缺失的工具自动安装
-**重试机制**: 网络下载失败自动重试最多3次
#### 3. K3s部署 (`deploy.sh`)
- ✅ 使用Ansible的幂等特性
- ✅ 重复执行不会重新安装已存在的组件
- ✅ kubectl配置自动检测和更新
#### 4. Gitea部署 (`deploy-gitea.sh`)
- ✅ 使用Helm的幂等特性
- ✅ 命名空间已存在时自动跳过创建
- ✅ 重复执行会更新配置而不是重新安装
#### 5. ArgoCD部署 (`deploy-argocd.sh`)
- ✅ 使用 `kubectl apply` 声明式部署
- ✅ 自动检测htpasswd和yq工具
- ✅ 密码更新使用patch操作安全幂等
#### 6. HTTPS配置 (`deploy-https.sh`)
- ✅ cert-manager CRDs和组件使用 `kubectl apply`
- ✅ ClusterIssuer和Ingress可重复应用
- ✅ 证书自动续期,无需手动干预
### 测试幂等性
重复执行部署脚本验证幂等性:
```bash
# 第一次部署
./scripts/deploy-all.sh
# 验证部署
./scripts/verify-deployment.sh
# 重复执行(应该跳过所有已完成步骤)
./scripts/deploy-all.sh
# 再次验证(状态应该不变)
./scripts/verify-deployment.sh
```
### 重装系统后的部署流程
1. **准备环境**:
```bash
# 创建fei用户如果不存在
sudo useradd -m -s /bin/bash fei
sudo passwd fei
# 配置sudo权限
echo "fei ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/fei
```
2. **复制配置文件**:
```bash
# 备份配置文件
cp config/cluster-vars.yml ~/cluster-vars.yml.backup
# 重装系统后恢复
cp ~/cluster-vars.yml.backup config/cluster-vars.yml
```
3. **一键部署**:
```bash
./scripts/deploy-all.sh
```
4. **验证部署**:
```bash
./scripts/verify-deployment.sh
```
### 常见问题
**Q: 部署失败后如何继续?**
A: 直接重新运行 `./scripts/deploy-all.sh`,脚本会自动跳过已完成的步骤。
**Q: 如何从头开始部署?**
A: 运行 `./scripts/deploy-all.sh --reset` 清除状态后重新部署。
**Q: 网络下载失败怎么办?**
A: 脚本会自动重试3次如果仍然失败检查网络连接后重新运行。
**Q: 如何查看部署日志?**
A: 查看 `deployment.log` 文件获取详细日志。

# 🔥 紧急修复:无法访问服务的问题
## 问题诊断
**服务状态正常:**
```
argocd-server NodePort 80:31875/TCP,443:31064/TCP
gitea-http NodePort 3000:32158/TCP
demo-nginx NodePort 80:30080/TCP
test-app NodePort 80:30081/TCP
```
**问题原因阿里云ECS安全组未开放NodePort端口**
从本地无法访问这些端口但从master节点内部可以访问说明是云服务器安全组阻止了外部访问。
## 🔧 解决方案
### 方案1: 配置阿里云安全组(推荐)
#### 步骤1: 登录阿里云控制台
1. 访问 https://ecs.console.aliyun.com/
2. 登录你的阿里云账号
#### 步骤2: 找到安全组
1. 左侧菜单选择 **网络与安全****安全组**
2. 找到你的ECS实例所在的安全组
#### 步骤3: 添加入方向规则
点击 **配置规则****入方向****手动添加**,添加以下规则:
| 端口范围 | 授权对象 | 描述 |
|---------|---------|------|
| 30080/30080 | 0.0.0.0/0 | Demo App |
| 30081/30081 | 0.0.0.0/0 | Test App |
| 31875/31875 | 0.0.0.0/0 | ArgoCD HTTP |
| 31064/31064 | 0.0.0.0/0 | ArgoCD HTTPS |
| 32158/32158 | 0.0.0.0/0 | Gitea HTTP |
| 30625/30625 | 0.0.0.0/0 | Gitea SSH |
或者一次性开放NodePort范围
| 端口范围 | 授权对象 | 描述 |
|---------|---------|------|
| 30000/32767 | 0.0.0.0/0 | K3s NodePort范围 |
**注意:** 如果只想允许特定IP访问`0.0.0.0/0` 改为你的公网IP。
#### 步骤4: 保存并等待生效
保存规则后等待1-2分钟生效。
### 方案2: 使用Traefik Ingress推荐用于生产
Traefik已经部署并监听在80和443端口我们可以通过Ingress访问服务。
#### 2.1 配置ArgoCD Ingress
```bash
ssh fei@8.216.38.248
kubectl apply -f - <<EOF
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: argocd-server
namespace: argocd
annotations:
traefik.ingress.kubernetes.io/router.entrypoints: web
traefik.ingress.kubernetes.io/router.tls: "false"
spec:
rules:
- host: argocd.jpc.net3w.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: argocd-server
port:
number: 80
EOF
```
#### 2.2 配置Gitea Ingress
```bash
kubectl apply -f - <<EOF
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: gitea
namespace: gitea
annotations:
traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
rules:
- host: git.jpc.net3w.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: gitea-http
port:
number: 3000
EOF
```
#### 2.3 配置Demo App Ingress
```bash
kubectl apply -f - <<EOF
apiVersion: networking.k8s.io/v1
kind: Ingress
metad name: demo-app
namespace: default
annotations:
traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
rules:
- host: demo.jpc.net3w.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: demo-nginx
port:
number: 80
EOF
```
#### 2.4 配置DNS或hosts文件
**选项A: 配置DNS生产环境**
在DNS管理面板添加A记录
```
argocd.jpc.net3w.com → 8.216.38.248
git.jpc.net3w.com → 8.216.38.248
demo.jpc.net3w.com → 8.216.38.248
test.jpc.net3w.com → 8.216.38.248
```
**选项B: 配置本地hosts文件测试**
Linux/Mac:
```bash
sudo tee -a /etc/hosts <<EOF
8.216.38.248 argocd.jpc.net3w.com
8.216.38.248 git.jpc.net3w.com
8.216.38.248 demo.jpc.net3w.com
8.216.38.248 test.jpc.net3w.com
EOF
```
Windows (管理员权限):
```
编辑 C:\Windows\System32\drivers\etc\hosts
添加:
8.216.38.248 argocd.jpc.net3w.com
8.216.38.248 git.jpc.net3w.com
8.216.38.248 demo.jpc.net3w.com
8.216.38.248 test.jpc.net3w.com
```
然后访问:
- http://argocd.jpc.net3w.com
- http://git.jpc.net3w.com
- http://demo.jpc.net3w.com
- http://test.jpc.net3w.com
### 方案3: 使用SSH端口转发临时测试
如果暂时无法修改安全组可以使用SSH端口转发
```bash
# 转发Arsh -L 8080:localhost:31875 fei@8.216.38.248 -N &
# 转发Gitea
ssh -L 8081:localhost:32158 fei@8.216.38.248 -N &
# 转发Demo App
ssh -L 8082:localhost:30080 fei@8.216.38.248 -N &
# 转发Test App
ssh -L 8083:localhost:30081 fei@8.216.38.248 -N &
```
然后在本地浏览器访问:
- ArgoCD: http://localhost:8080
- Gitea: http://localhost:8081
- Demo App: http://localhost:8082
- Test App: http://localhost:8083
## 🎯 推荐方案
### 短期(立即可用)
1. **使用SSH端口转发**方案3- 立即可用,无需等待
2. **配置阿里云安全组**方案1- 开放NodePort端口
### 长期(生产环境)
1. **使用Traefik Ingress**方案2- 只需开放80/443端口
2. **配置HTTPS证书** - 使用cert-manager + Let's Encrypt
3. **配置DNS解析** - 使用域名访问
## 📊 验证访问
### 验证NodePort访问需要开放安全组
```bash
# 从本地测试
curl http://8.216.38.248:30080 # Demo App
curl http://8.216.38.248:30081 # Test App
curl http://8.216.38.248:32158 # Gitea
curl -k https://8.216.38.248:31875 # ArgoCD
```
### 验证Ingress访问需要配置DNS或hosts
```bash
curl http://demo.jpc.net3w.com
curl http://test.jpc.net3w.com
curl http://git.jpc.net3w.com
curl http://argocd.jpc.net3w.com
```
### 从master节点内部测试已验证可用
```bash
ssh fei@8.216.38.248

kubectl get ingress -A
```
### 2. 检查Pod状态
```bash
kubectl get pods -A
kubectl logs -n argocd deployment/argocd-server
kubectl logs -n gitea -l app.kubernetes.io/name=gitea
```
### 3. 检查Traefik
```bash
kubectl get pods -n kube-system -l app.kubernetes.io/name=traefik
kubectl logs -n kube-system -l app.kubernetes.io/name=traefik
```
### 4. 测试端口连通性
```bash
# 从本地测试
nc -zv 8.216.38.248 80
nc -zv 8.216.38.248 443
nc -zv 8.216.38.248 30080
nc -zv 8.216.38.248 31875
```
## 📝 总结
**当前状态:**
- ✅ K3s集群运行正常
- ✅ 所有服务部署成功

# K3s + GitOps 使用指南
## 📊 当前部署状态总结
### ✅ 1. 幂等性配置已修复
所有配置文件已经修复,支持完全幂等性部署:
-**inventory/hosts.ini**: 使用正确的组名 `server``agent`
-**api_endpoint**: 配置为内网IP `172.23.96.138`
-**worker节点**: 使用内网IP连接master配置正确的token
-**验证**: 最后一次Ansible运行显示 `changed=0`,配置稳定
**可以安全地重复运行部署脚本,不会出错!**
### ✅ 2. 测试项目已创建
已创建完整的测试应用 `test-app`,包含:
- **应用**: 2个nginx副本带自定义HTML页面
- **Service**: NodePort 30081
- **Ingress**: 域名访问 `test.jpc.net3w.com`
- **Git仓库**: http://8.216.38.248:32158/k3s-apps/test-app
- **ArgoCD应用**: 自动同步部署
## 🌐 访问方式
### 1. NodePort访问直接可用
```bash
# 通过任意节点访问
curl http://8.216.38.248:30081
curl http://8.216.41.97:30081
curl http://8.216.33.69:30081
```
### 2. 域名访问需要DNS配置
**方式A: 配置本地hosts文件测试用**
```bash
# Linux/Mac
sudo echo "8.216.38.248 test.jpc.net3w.com" >> /etc/hosts
# Windows (管理员权限)
# 编辑 C:\Windows\System32\drivers\etc\hosts
# 添加: 8.216.38.248 test.jpc.net3w.com
```
**方式B: 配置DNS解析生产用**
在你的域名DNS管理面板添加A记录
```
test.jpc.net3w.com → 8.216.38.248
```
配置后访问:
```bash
curl http://test.jpc.net3w.com
# 或在浏览器打开: http://test.jpc.net3w.com
```
## 🔄 更新应用演示
### 方式1: 使用更新脚本(推荐)
在master节点上执行
```bash
ssh fei@8.216.38.248
cd /home/fei/k3s/test-app
# 更新到v2.0(粉红色背景)
./update-app.sh v2.0
# 更新到v3.0(蓝色背景)
./update-app.sh v3.0
# 更新到v4.0(绿色背景)
./update-app.sh v4.0
```
### 方式2: 手动修改并提交
```bash
ssh fei@8.216.38.248
cd /home/fei/k3s/test-app
# 1. 修改配置
vim manifests/deployment.yaml
# 修改 ConfigMap 中的内容,比如版本号、颜色等
# 2. 提交到Git
git add .
git commit -m "Update to v2.0"
git push
# 3. 等待ArgoCD自动同步3分钟内
kubectl get application test-app -n argocd -w
```
### 查看更新状态
```bash
# 查看ArgoCD应用状态
kubectl get application test-app -n argocd
# 查看Pod状态
kubectl get pods -l app=test-app
# 查看实时日志
kubectl logs -f -l app=test-app
# 访问应用验证更新
curl http://8.216.38.248:30081 | grep Version
```
## 📦 将部署配置存入Git
### 1. 初始化Git仓库
```bash
cd /home/fei/opk3s/k3s自动化部署
# 初始化Git
git init -b main
# 添加文件
git add .gitignore
git add README-DEPLOYMENT.md
git add USAGE-GUIDE.md
git add config/cluster-vars.yml.example
git add scripts/
git add k3s-ansible/inventory/hosts.ini
# 提交
git commit -m "Initial commit: K3s deployment configuration"
```
### 2. 推送到远程仓库
**选项A: 推送到Gitea内部**
```bash
# 在Gitea创建仓库 k3s-deployment
# 然后推送
git remote add origin http://8.216.38.248:32158/k3s-apps/k3s-deployment.git
git push -u origin main
```
**选项B: 推送到GitHub/GitLab外部**
```bash
# 创建GitHub仓库后
git remote add origin https://github.com/YOUR_USERNAME/k3s-deployment.git
git push -u origin main
```
### 3. 下次更新配置
```bash
# 修改配置文 config/cluster-vars.yml
# 重新生成inventory
python3 scripts/generate-inventory.py
# 提交更改
git add k3s-ansible/inventory/hosts.ini
git commit -m "Update cluster configuration"
git push
# 重新部署(幂等操作)
cd k3s-ansible
ansible-playbook site.yml -i inventory/hosts.ini -e "@../config/cluster-vars.yml"
```
## 🚀 创建新的应用
### 1. 在Gitea创建新仓库
```bash
ssh fei@8.216.38.248
cd /home/fei/k3s
# 创建新应用目录
mkdir -p my-new-app/manifests
# 创建Kubernetes清单
cat > my-new-app/manifests/deployment.yaml << 'EOF'
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-new-app

namespace: default
spec:
type: NodePort
selector:
app: my-new-app
ports:

nodePort: 30082
EOF
# 初始化Git并推送
cd my-new-app
git init -b main
git add .
git commit -m "Initial commit"
# 推送到Gitea需要先在Gitea创建仓库
git remote add origin http://argocd:ArgoCD%402026@localhost:32158/k3s-apps/my-new-app.git
git push -u origin main
```
### 2. 创建ArgoCD应用
```bash
kubectl apply -f - << 'EOF'
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: my-new-app
namespace: argocd
spec:
project: default
source:
repoURL: http://gitea-http.gitea.svc.cluster.local:3000/k3s-apps/my-new-app.git
targetRevision: main
path: manifests
destination:
server: https://kubernetes.default.svc
namespace: default
syncPolicy:
automated:
prune: true
selfHeal: true
EOF
```
## 📊 监控和管理

- **ArgoCD用户**: argocd / ArgoCD@2026
功能:
- 管理Git仓库
- 查看提交历史
- 创建新仓库
- 管理用户和权限
### 命令行管理
```bash
# 查看所有ArgoCD应用
kubectl get application -n argocd
# 查看应用详情
kubectl describe application test-app -n argocd
# 手动触发同步
kubectl patch application test-app -n --type merge -p '{"metadotations":{"argocd.argoproj.io/refresh":"hard"}}}'
# 查看所有Pod
kubectl get pods -A
# 查看特定应用的Pod
kubectl get pods -l app=test-app
# 查看Ingress
kubectl get ingress -A
```
## 🔧 故障排查
### 应用无法访问
1. **检查Pod状态**
```bash
kubectl get pods -l app=test-app
kubectl describe pod <pod-name>
kubectl logs <pod-name>
```
2. **检查Service**
```bash
kubectl get svc test-app
kubectl describe svc test-app
```
3. **检查Ingress**
```bash
kubectl get ingress test-app
kubectl describe ingress test-app
```
### ArgoCD同步失败
1. **查看应用状态**
```bash
kubectl get application test-app -n argocd
kubectl describe application test-app -n argocd
```
2. **查看ArgoCD日志**
```bash
kubectl logs -n argocd deployment/argocd-application-controller
kubectl logs -n argocd deployment/argocd-repo-server
```
3. **检查Git仓库连接**
```bash
# 在master节点测试
curl http://gitea-http.gitea.svc.cluster.local:3000/k3s-apps/test-app.git
```
### 域名无法访问
1. **检查DNS解析**
```bash
nslookup test.jpc.net3w.com
# 或
dig test.jpc.net3w.com
```
2. **检查Traefik Ingress Controller**
```bash
kubectl get pods -n kube-system -l app.kubernetes.io/name=traefik
kubectl logs -n kube-system -l app.kubernetes.io/name=traefik
```
3. **临时使用hosts文件**
```bash
# 添加到 /etc/hosts
8.216.38.248 test.jpc.net3w.com
```
## 📝 最佳实践
1. **使用Git管理所有配置**
- 所有Kubernetes清单文件都应该在Git中
- 使用分支管理不同环境dev/staging/prod
2. **定期备份**
- 备份Gitea数据`kubectl exec -n gitea <pod> -- tar czf /tmp/backup.tar.gz /data`
- 备份ArgoCD配置`kubectl get application -n argocd -o yaml > argocd-apps-backup.yaml`
3. **监控资源使用**
```bash
kubectl top nodes
kubectl top pods -A
```
4. **使用命名空间隔离应用**
```bash
kubectl create namespace production
kubectl create namespace staging
```
5. **配置资源限制**
在Deployment中添加
```yaml
resources:
requests:
memory: "64Mi"
cpu: "100m"
limits:
memory: "128Mi"
cpu: "200m"
```
## 🎯 下一步
1. **配置HTTPS**
- 安装cert-manager
- 配置Let's Encrypt自动证书
2. **添加监控**
- 部署Prometheus + Grafana
- 配置告警规则
3. **配置CI/CD**
- 集成Gitea Actions或Jenkins
- 自动构建Docker镜像
4. **多环境管理**
- 使用ArgoCD ApplicationSet
- 管理dev/staging/prod环境

# Nginx Test Application
这是一个由ArgoCD管理的Nginx测试应用用于演示GitOps自动化部署。
## 应用信息
- **应用名称**: nginx-test
- **镜像**: nginx:1.25-alpine
- **副本数**: 2
- **域名**: ${NGINX_DOMAIN}
- **命名空间**: default
## 架构说明
\`\`\`
Git仓库 (Gitea) → ArgoCD监控 → 自动同步 → K3s集群部署
\`\`\`
## 访问方式
### 通过域名访问(推荐)
\`\`\`bash
curl https://${NGINX_DOMAIN}
\`\`\`
### 通过NodePort访问
\`\`\`bash
# 获取Service信息
kubectl get svc nginx-test -n default
# 访问应用
curl http://<NODE_IP>:<NODE_PORT>
\`\`\`
## 更新应用
### 方式1: 修改版本号
编辑 \`manifests/configmap.yaml\` 中的 HTML 内容,修改版本号:
\`\`\`html
<div class="version">Version: v2.0</div>
\`\`\`
### 方式2: 修改副本数
编辑 \`manifests/deployment.yaml\`
\`\`\`yaml
spec:
replicas: 3 # 修改副本数
\`\`\`
### 方式3: 更新Nginx配置
编辑 \`manifests/configmap.yaml\` 中的 nginx 配置。
提交更改后ArgoCD会在3分钟内自动检测并部署新版本。
## 监控部署状态
\`\`\`bash
# 查看ArgoCD Application状态
kubectl get application nginx-app -n argocd
# 查看Pod状态
kubectl get pods -l app=nginx-test -n default
# 查看Ingress状态
kubectl get ingress nginx-test -n default
# 查看应用日志
kubectl logs -l app=nginx-test -n default --tail=50
\`\`\`
## 健康检查
应用提供了健康检查端点:
\`\`\`bash
curl https://${NGINX_DOMAIN}/health
\`\`\`
## 故障排查
### 检查Pod状态
\`\`\`bash
kubectl describe pod -l app=nginx-test -n default
\`\`\`
### 检查Ingress
\`\`\`bash
kubectl describe ingress nginx-test -n default
\`\`\`
### 检查ArgoCD同步状态
\`\`\`bash
kubectl describe application nginx-app -n argocd
\`\`\`
## GitOps工作流
1. 开发者修改 \`manifests/\` 目录下的配置文件
2. 提交并推送到Git仓库
3. ArgoCD自动检测到变化每3分钟轮询一次
4. ArgoCD自动同步并部署到K3s集群
5. 应用自动更新无需手动执行kubectl命令
## 回滚操作
如果需要回滚到之前的版本:
\`\`\`bash
# 查看Git历史
git log --oneline
# 回滚到指定commit
git revert <commit-hash>
git push
# 或者通过ArgoCD UI进行回滚
\`\`\`
## 技术栈
- **容器编排**: Kubernetes (K3s)
- **Web服务器**: Nginx 1.25
- **GitOps工具**: ArgoCD
- **Git仓库**: Gitea
- **Ingress控制器**: Nginx Ingress Controller
- **证书管理**: cert-manager (Let's Encrypt)
## 注意事项
1. 确保DNS已正确配置${NGINX_DOMAIN} 指向K3s集群节点IP
2. 首次访问HTTPS可能需要等待证书签发约1-2分钟
3. ArgoCD默认每3分钟检查一次Git仓库更新
4. 可以通过ArgoCD UI手动触发同步以立即部署更改
