nginx-proxy设置一个运行nginx和docker-gen的容器。docker-gen为nginx生成反向代理配置，并在启动和停止容器时重新加载nginx。 使用nginx-proxy来反向代理portainer，并且使用https域名加密访问。

portainer使用nginx-proxy配置代理添加证书

创建一个bridge网络

1

docker network create nginx_networks

ubuntu@VM-0-6-ubuntu:~/project$ docker network ls

nginx-proxy配置

采用docker-compose项目进行服务编排

创建项目文件夹

1
2

mkdir nginx-proxy
cd nginx-proxy

version: '3'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy:alpine
    container_name: nginx-proxy
    restart: always
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./nginx/log:/var/log/nginx
      - ./nginx/conf.d:/etc/nginx/conf.d
      - ./nginx/certs:/etc/nginx/certs
      - /var/run/docker.sock:/tmp/docker.sock:ro
    networks:
      - nginx_networks
  whoami:
    image: jwilder/whoami
    environment:
      - VIRTUAL_HOST=whoami.local
    networks:
      - nginx_networks
networks:
  nginx_networks:
    external: true

注：

• networks加入上一步已经创建好的网络中
• whoami用来测试
• volumes挂载相应的数据
  • log把日志挂出来
  • conf.d便于自定义
  • certs配置SSL证书
  • *docker.sock*主要用于监听docker容器为nginx生成反向代理配置，并在启动和停止容器时重新加载nginx。

启动项目容器

1

docker-compose up -d

验证

2

ubuntu@VM-0-6-ubuntu:~/project/nginx-proxy$ curl -H "Host: whoami.local" localhost
I'm eb5b18a676c8

会输出jwilder/whoami的容器ID

portainer配置

同样是采用docker-compose项目进行服务编排

cd ..
mkdir portainer
cd portainer

version: '3'
services:
  portainer:
    image: portainer/portainer
    container_name: portainer
    restart: always
    command: -H unix:///var/run/docker.sock
    environment:
      - VIRTUAL_HOST=portainer.weii.ink
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - portainer_data:/data
    networks:
      - nginx_networks
volumes:
  portainer_data:
networks:
  nginx_networks:
    external: true

注：

• networks与nginx-proxy加入同一个网络中
• volumes存放portainer数据
• environment环境变量配置portainer容器使用的域名，这个变量是nginx-proxy使用的

启动

1

docker-compose up -d

然后就可以用http://portainer.weii.ink访问啦！

启用证书加密

申请免费的域名证书

• 我已经申请过了...不在说了
• 证书文件命名为portainer.weii.ink.crt和portainer.weii.ink.key
• 证书文件放到nginx-proxy/nginx/certs路径下
• 重启nginx-proxy

验证

nginx-proxy已经自动配置好代理，以及SSL证书

最后

访问https://portainer.weii.ink就会有SSL证书啦！
