Minikube 本地 Registry 管理 Laravel 和 Vue 镜像

使用 Minikube 内置的 registry 可以方便地在本地管理 Laravel 和 Vue 镜像，无需依赖外部 registry（如 Docker Hub）。以下是完整的配置方案： 
 1. 启用 Minikube 的本地 Registry 
 # 启动 Minikube 并启用 registry 插件
minikube start --driver=docker --insecure-registry="10.0.0.0/24"
minikube addons enable registry

# 查看 registry 服务
kubectl get svc -n kube-system | grep registry

# 设置端口转发，使本地可以访问 registry
kubectl port-forward --namespace kube-system service/registry 5000:80 &
 
 2. 配置 Docker 使用 Minikube 的 Registry 
 # 设置环境变量指向 Minikube 的 Docker daemon
eval $(minikube docker-env)

# 验证是否连接到 Minikube 的 Docker
docker info | grep "Name: minikube"
 
 3. 构建和推送 Laravel 镜像 
 Laravel Dockerfile 示例 
 # Dockerfile.laravel
FROM php:8.1-fpm

# 安装依赖
RUN apt-get update && apt-get install -y \
 git \
 curl \
 libpng-dev \
 libonig-dev \
 libxml2-dev \
 zip \
 unzip \
 libzip-dev

# 安装 PHP 扩展
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd zip

# 安装 Composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

# 设置工作目录
WORKDIR /var/www

# 复制项目文件
COPY . .

# 安装依赖
RUN composer install --optimize-autoloader --no-dev

# 优化配置
RUN php artisan config:cache && \
 php artisan route:cache && \
 php artisan view:cache

# 暴露端口
EXPOSE 9000

# 启动命令
CMD ["php-fpm"]
 
 构建和推送 Laravel 镜像 
 # 构建镜像
docker build -t localhost:5000/laravel-app:latest -f Dockerfile.laravel .

# 推送镜像到本地 registry
docker push localhost:5000/laravel-app:latest

# 验证镜像是否在 registry 中
curl http://localhost:5000/v2/_catalog
 
 4. 构建和推送 Vue 镜像 
 Vue Dockerfile 示例 
 # Dockerfile.vue
FROM node:16 as builder

WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

FROM nginx:alpine
COPY --from=builder /app/dist /usr/share/nginx/html
COPY nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
 
 相关 Nginx 配置 
 # nginx.conf
server {
 listen 80;
 server_name localhost;

 location / {
 root /usr/share/nginx/html;
 index index.html;
 try_files $uri $uri/ /index.html;
 }

 location /api {
 proxy_pass http://laravel-backend:9000;
 proxy_set_header Host $host;
 proxy_set_header X-Real-IP $remote_addr;
 }
}
 
 构建和推送 Vue 镜像 
 # 构建镜像
docker build -t localhost:5000/vue-app:latest -f Dockerfile.vue .

# 推送镜像到本地 registry
docker push localhost:5000/vue-app:latest

# 验证镜像
curl http://localhost:5000/v2/_catalog
 
 5. 部署 Kubernetes 资源 
 Laravel 部署配置 
 # laravel-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
 name: laravel-backend
 namespace: laravel-vue-app
spec:
 replicas: 2
 selector:
 matchLabels:
 app: laravel-backend
 template:
 metadata:
 labels:
 app: laravel-backend
 spec:
 containers:
 - name: laravel-app
 image: localhost:5000/laravel-app:latest
 imagePullPolicy: Always
 env:
 - name: DB_HOST
 value: "mysql"
 - name: DB_DATABASE
 value: "laravel"
 - name: DB_USERNAME
 value: "root"
 - name: DB_PASSWORD
 valueFrom:
 secretKeyRef:
 name: laravel-secrets
 key: db-password
 ports:
 - containerPort: 9000
 resources:
 requests:
 cpu: "100m"
 memory: "256Mi"
 limits:
 cpu: "500m"
 memory: "512Mi"
 
 Vue 部署配置 
 # vue-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
 name: vue-frontend
 namespace: laravel-vue-app
spec:
 replicas: 2
 selector:
 matchLabels:
 app: vue-frontend
 template:
 metadata:
 labels:
 app: vue-frontend
 spec:
 containers:
 - name: vue-app
 image: localhost:5000/vue-app:latest
 imagePullPolicy: Always
 ports:
 - containerPort: 80
 resources:
 requests:
 cpu: "50m"
 memory: "128Mi"
 limits:
 cpu: "200m"
 memory: "256Mi"
 
 6. 验证部署 
 # 应用所有配置
kubectl apply -f namespace.yaml
kubectl apply -f mysql-pvc.yaml
kubectl apply -f mysql-deployment.yaml
kubectl apply -f mysql-service.yaml
kubectl apply -f redis-deployment.yaml
kubectl apply -f redis-service.yaml
kubectl apply -f laravel-deployment.yaml
kubectl apply -f laravel-service.yaml
kubectl apply -f vue-deployment.yaml
kubectl apply -f vue-service.yaml
kubectl apply -f ingress.yaml

# 查看 pod 状态
kubectl get pods -n laravel-vue-app -w

# 获取应用 URL
minikube service list
 
 7. 自动化构建和部署脚本 
 创建 build-and-deploy.sh 脚本： 
 #!/bin/bash

# 构建 Laravel 镜像
echo "Building Laravel image..."
docker build -t localhost:5000/laravel-app:latest -f Dockerfile.laravel .
docker push localhost:5000/laravel-app:latest

# 构建 Vue 镜像
echo "Building Vue image..."
docker build -t localhost:5000/vue-app:latest -f Dockerfile.vue .
docker push localhost:5000/vue-app:latest

# 重新部署 Kubernetes 资源
echo "Redeploying applications..."
kubectl rollout restart deployment/laravel-backend -n laravel-vue-app
kubectl rollout restart deployment/vue-frontend -n laravel-vue-app

echo "Deployment complete!"
 
 8. 常见问题解决 
 镜像拉取问题 
 如果遇到镜像拉取问题，可以尝试： 
 # 确保 Minikube 使用本地 Docker daemon
eval $(minikube docker-env)

# 检查 registry 是否运行
kubectl get pods -n kube-system | grep registry

# 如果 registry 有问题，重新启用
minikube addons disable registry
minikube addons enable registry
 
 性能优化 
 对于开发环境，可以配置资源限制： 
 # 在 deployment 中添加
resources:
 requests:
 cpu: "100m"
 memory: "128Mi"
 limits:
 cpu: "500m"
 memory: "512Mi"
 
 9. 清理资源 
 # 删除部署
kubectl delete -f .

# 禁用 registry
minikube addons disable registry

# 删除本地镜像
docker rmi localhost:5000/laravel-app:latest
docker rmi localhost:5000/vue-app:latest
 
 通过这种方式，您可以在 Minikube 环境中完全本地化管理 Laravel 和 Vue 镜像，无需依赖外部 registry，适合开发和测试环境使用。
