docker - Nginx反向代理:使用jwilder/nginx-proxy为gitlab容器设置正确的端口

Question

我需要使用Nginx反向代理。因此，我使用jwilder/nginx-proxy.
Also I'm using gitLab as a docker container.
So I came up with this docker-compose file, but accessing ci.server.com gives me a 502 Bad Gateway`错误。

我需要一些帮助来设置此Docker容器的正确端口

version: '3.3'
services:
  nginx:
    container_name: 'nginx'
    image: jwilder/nginx-proxy:alpine
    restart: 'always'
    ports:
      - 80:80
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

  gitlab:
    container_name: gitlab
    image: 'gitlab/gitlab-ce:10.0.2-ce.0'
    restart: always
    hostname: 'ci.server.com'
    ports:
      - '50022:22'
    volumes:
      - '/opt/gitlab/config:/etc/gitlab'
      - '/opt/gitlab/logs:/var/log/gitlab'
      - '/opt/gitlab/data:/var/opt/gitlab'
      - '/opt/gitlab/secret:/secret/gitlab/backups'
      - '/etc/letsencrypt:/etc/letsencrypt'
    environment:
      VIRTUAL_HOST: ci.server.com
      VIRTUAL_PORT: 50022

在切换到Nginx反向代理之前，我使用了此docker-compose设置，该设置可以正常工作。我没有得到“转换”的不同或错误。

version: '3.3'

    container_name: 'nginx'
    image: 'nginx:1.13.5'
    restart: 'always'
    ports:

    volumes:

      - '/opt/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro'
      - '/etc/letsencrypt:/etc/letsencrypt'
    links:
      - 'gitlab'

  gitlab:
    container_name: gitlab
    image: 'gitlab/gitlab-ce:10.0.2-ce.0'
    restart: always
    hostname: 'ci.server.com'

      - '/opt/gitlab/logs:/var/log/gitlab'
      - '/opt/gitlab/data:/var/opt/gitlab'
      - '/opt/gitlab/secret:/secret/gitlab/backups'
      - '/etc/letsencrypt:/etc/letsencrypt'

您应该在您的环境中设置VIRTUAL_PORT: 80。

代理实际上正在尝试将80端口重定向到SSH端口。

要将SSL与jwilderproxy一起使用，您可以查看here

例如，我用这个。
version: '3/3'
services:
gitlab:
container_name: gitlab
image: 'gitlab/gitlab-ce:10.0.2-ce.0'
restart: always
hostname: 'ci.server.com'
ports:
- '50022:22'
volumes:
- '/opt/gitlab/config:/etc/gitlab'
- '/opt/gitlab/logs:/var/log/gitlab'
- '/opt/gitlab/data:/var/opt/gitlab'
- '/opt/gitlab/secret:/secret/gitlab/backups'
- '/etc/letsencrypt:/etc/letsencrypt'
environment:
- VIRTUAL_HOST=ci.server.com
- VIRTUAL_PORT=80
- LETSENCRYPT_HOST=ci.server.com
- LETSENCRYPT_EMAIL=youremail
