如何使用nginx(安装在docker上)反向代理gitlab(也安装在docker上)

Question

我按照官方文档安装了gitlab。

sudo docker run --detach \
  --hostname git.stupidpz.com \
  --publish 8443:443 --publish 880:80 --publish 822:22 \
  --name gitlab \
  --restart always \
  --volume $GITLAB_HOME/config:/etc/gitlab \
  --volume $GITLAB_HOME/logs:/var/log/gitlab \
  --volume $GITLAB_HOME/data:/var/opt/gitlab \
  --shm-size 256m \
  gitlab/gitlab-ee:latest

现在我想使用Nginx（自己安装的）来反向代理gitlab，而不是gitlab容器自带的nginx。

根据官方文档我添加了一些代码gitlab.rb

# Define the external url
external_url 'http://git.stupidpz.com'

# Disable the built-in nginx
nginx['enable'] = false

# Disable the built-in puma
puma['enable'] = false

# Set the internal API URL
gitlab_rails['internal_api_url'] = 'http://git.stupidpz.com'

# Define the web server process user (ubuntu/nginx)
web_server['external_users'] = ['nginx']

然后gitlab就无法访问了，我在这个文件中发现了一些错误日志/var/log/gitblab/gitlab_workhorse/current

# Define the external url
external_url 'http://git.stupidpz.com'

# Disable the built-in nginx
nginx['enable'] = false

# Disable the built-in puma
puma['enable'] = false

# Set the internal API URL
gitlab_rails['internal_api_url'] = 'http://git.stupidpz.com'

# Define the web server process user (ubuntu/nginx)
web_server['external_users'] = ['nginx']

除了添加一些代码之外什么也没做gitlab.rb。

我想知道这dial tcp 127.0.0.1:8080是从哪里来的？

希望你能帮助我，或者给我一个正确的demo。非常感谢。这个问题已经困扰我两天了

现在我明白为什么我不能让它工作了，我混淆了使用现有的 Passenger/NGINX 安装和使用非捆绑的 Web 服务器 如果你只需要使用你自己的 nginx 来代理 gitlab（它们都安装在docker）你只需要添加两行到gitlab.rb.

# Disable the built-in nginx
nginx['enable'] = false
# Define the web server process user (ubuntu/nginx)
web_server['external_users'] = ['nginx']

这是nginx 的conf

upstream gitlab-workhorse {
  server unix://var/opt/gitlab/gitlab-workhorse/sockets/socket fail_timeout=0;
}

  listen *:80;
  server_name git.example.com;

  # Make sure Passenger runs as the correct user and group to
  # prevent permission issues
  passenger_user git;
  passenger_group git;

  # Enable Passenger & keep at least one instance running at all times

  # For protocol upgrades from HTTP/1.0 to HTTP/1.1 we need to provide Host header if its missing
  if ($http_host = "") {
  # use one of values defined in server_name
    set $http_host_with_default "git.example.com";
  }

  if ($http_host != "") {
    set $http_host_with_default $http_host;
  }

  location @gitlab-workhorse {

    ## https://github.com/gitlabhq/gitlabhq/issues/694
    ## Some requests take more than 30 seconds.
    proxy_read_timeout      3600;
    proxy_connect_timeout   300;
    proxy_redirect          off;

    # Do not buffer Git HTTP responses
    proxy_buffering off;

    proxy_set_header    Host                $http_host_with_default;
    proxy_set_header    X-Real-IP           $remote_addr;

    proxy_pass http://gitlab-workhorse;

    ## The following settings only work with NGINX 1.7.11 or newer

  }

  ## Enable gzip compression as per rails guide:
  ## http://guides.rubyonrails.org/asset_pipeline.html#gzip-compression
  ## WARNING: If you are using relative urls remove the block below
  ## See config/application.rb under "Relative url support" for the list of
  ## other files that need to be changed for relative url support
  location ~ ^/(assets)/ {
    root /opt/gitlab/embedded/service/gitlab-rails/public;
    gzip_static on; # to serve pre-gzipped version
    expires max;
    add_header Cache-Control public;
  }

  ## To access Grafana
  location /-/grafana/ {
    proxy_pass http://localhost:3000/;
  }

  error_page 502 /502.html;
}

最后但并非最不重要的一点是，您需要将另一个 bash 添加到您的 nginx 容器中，

-v /var/opt/gitlab:/var/opt/gitlab

这将使您的 nginx 容器连接到 gitlab 容器。否则您将得到“cannot find var/opt/gitlab/gitlab-workhorse/sockets/socket”。
