1.2 容器化带来的价值
| 传统部署 | 容器化部署 |
|---|---|
| 环境配置复杂 | 环境一致性 |
| 扩展性差 | 弹性伸缩 |
| 资源利用率低 | 资源隔离 |
| 部署效率低 | 快速部署 |
二、Docker镜像构建实战
2.1 后端Spring Boot应用Dockerfile
# 后端Dockerfile
FROM eclipse-temurin:17-jre-alpine
# 设置工作目录
WORKDIR /app
# 复制JAR文件
COPY target/rest-api-example-*.jar app.jar
# 设置JVM参数
ENV JAVA_OPTS="-Xms512m -Xmx1024m -Dspring.profiles.active=prod"
# 暴露端口
EXPOSE 8080
# 健康检查
HEALTHCHECK --interval=30s --timeout=3s \
CMD curl -f http://localhost:8080/actuator/health || exit 1
# 启动应用
ENTRYPOINT ["sh", "-c", "java $JAVA_OPTS -jar app.jar"]
2.2 前端Vue应用Dockerfile
# 前端Dockerfile - 多阶段构建
FROM node:18-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
RUN npm run build
FROM nginx:alpine
# 复制构建产物
COPY --from=builder /app/dist /usr/share/nginx/html
# 复制nginx配置
COPY nginx.conf /etc/nginx/conf.d/default.conf
# 暴露端口
EXPOSE 80
# 健康检查
HEALTHCHECK --interval=30s --timeout=3s \
CMD curl -f http://localhost || exit 1
2.3 Nginx配置文件
# nginx.conf
server {
listen 80;
server_name localhost;
root /usr/share/nginx/html;
index index.html;
# 静态资源缓存
location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
expires 1y;
add_header Cache-Control "public, immutable";
}
# API代理
location /api/ {
proxy_pass http://diboot-backend:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
# SPA路由支持
location / {
try_files $uri $uri/ /index.html;
}
}
