nginx - 通过Jwilder的Nginx代理访问虚拟主机时出现502错误网关

Question

我有一个Nginx代理(Jwilder，默认配置)和Gitlab实例在同一主机上运行。git.myhost.com指向主机IP。
当使用下面的docker-compose.yml启动Gitlab时，访问http://git.myhost.com时会得到一个502 Bad Gateway。

在nginx-proxy容器中生成的/etc/nginx/conf.d/default.conf也看起来不错:

upstream git.myhost.com {
                # 2ab9168d-c69e-4725-8c20-31a194ad8d07
                server 172.17.0.13 vhost;
}
server {
        server_name git.myhost.com;
        listen 80 ;
        access_log /var/log/nginx/access.log vhost;
        location / {
                proxy_pass http://git.myhost.com;
        }
}

我在做什么错？

这是Gitlab的 docker-compose.yml:

gitlab-server:
  hostname: git.myhost.com
  expose:
  - "8100"
  ports:
  - 8101:22/tcp
#  - 8100:8100/tcp
  labels:
    io.rancher.sidekicks: gitlab-data
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'http://git.myhost.com'
      gitlab_rails['gitlab_shell_ssh_port'] = 8101
    VIRTUAL_HOST: git.myhost.com
    VIRTUAL_PORT: 8100
  image: gitlab/gitlab-ce:latest
  volumes_from:
  - gitlab-data

gitlab-data:
  labels:
    io.rancher.container.start_once: 'true'
  entrypoint:
  - /bin/true
  hostname: gitdata
  image: gitlab/gitlab-ce:latest
  volumes:
  - /etc/gitlab:/etc/gitlab
  - /var/log/gitlab:/var/log/gitlab
  - /var/opt/gitlab:/var/opt/gitlab

您应该按以下方式更改nginx:

upstream gitlab {
                # 2ab9168d-c69e-4725-8c20-31a194ad8d07
                server 172.17.0.13:8100;
}
server {
        server_name git.myhost.com;
        listen 80 ;
        access_log /var/log/nginx/access.log vhost;
        location / {
                proxy_pass http://gitlab;
        }
}

172.17.0.13是gitlab docker容器的IP地址。
