Docker安装Nginx和Jenkins服务

# docker-compose文件
version: '3'

networks:
  frontend:
    external: true

services:                                      # 容器
  docker_jenkins:
    user: root                                 # root权限
    restart: always                            # 重启方式
    image: jenkins/jenkins:lts                 # 使用的镜像
   # image: jenkins/jenkins:2.504.3


    container_name: jenkins                    # 容器名称
#    environment:
#      - TZ=Asia/Shanghai
#      - "JENKINS_OPTS=--prefix=/jenkins_home" ## 自定义 jenkins 访问前缀（上下文context）


    ports:                                     # 对外暴露的端口定义
      - 8080:8080
      

    volumes:                                   # 卷挂载路径
      - /docker/jenkins_home/:/var/jenkins_home     # 挂载到容器内的jenkins_home目录
      - /usr/local/bin/docker-compose:/usr/local/bin/docker-compose
  
  docker_nginx:                            # nginx-dev环境
    restart: always
    image: nginx
    container_name: nginx
    ports:
      - 80:80
    volumes:
      - /docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
      - /docker/html:/usr/share/nginx/html
      - /docker/nginx/logs:/var/log/nginx

# 拉取nginx
docker pull nginx:latest

# 拉取jenkins
docker pull jenkins/jenkins:lts

若出现这个错误
Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

# 设置镜像拉取加速器
# 可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
sudo mkdir -p /etc/docker

cat <<EOF | sudo tee /etc/docker/daemon.json

  {
    "registry-mirrors": ["https://docker.xuanyuan.me"]
  }
  EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

#安装完成后执行docker images可以清晰的看到当前docker下存在的镜像。
