As the title says, I'm trying to serve Gitlab through an nginx reverse proxy, with both programs being run in separate docker containers connected through a docker network. A picture as an example:
Linux Host ____________________________ | | | Docker | | __________________________| | | | | | Docker network (test-net)| | | ________________________| | | | | | | | nginx gitlab | Only nginx has a port bound to the host (443). | | | | | | | | TLS is terminated at nginx as well. | | | | | --> | | | in my test, I have nginx running as localhost. | | | |___| |___| | To access gitlab, hit https://localhost/git/ | | |________________________| | |__________________________| |____________________________| nginx runs with this docker command:
docker run -dit --network=test-net --name=nginx -p 443:443 -v "$PWD/conf":/etc/nginx:ro nginx:alpine && docker logs -f nginx
nginx.conf
<Removed unnecessary config from here, very basic setup> http { keepalive_timeout 65; server { listen 443 ssl; server_name localhost; ssl_certificate localhost.crt; ssl_certificate_key localhost.key; ssl_protocols TLSv1.2; ssl_ciphers HIGH:!aNULL:!MD5; location /git/ { proxy_pass http://test/; } } } gitlab.rb
<only relevant parts added here> external_url 'https://localhost' nginx['listen_port'] = 80 nginx['listen_https'] = false nginx['proxy_set_headers'] = { "Host" => "$http_host_with_default", "X-Real-IP" => "$remote_addr", "X-Forwarded-For" => "$proxy_add_x_forwarded_for", "X-Forwarded-Proto" => "http", "Upgrade" => "$http_upgrade", "X-Forwarded-Ssl" => "on", "Connection" => "$connection_upgrade" } nginx['custom_error_pages'] = { '404' => { 'title' => '404', 'header' => 'You\'ve been hit by !! You\'ve been struck by ! A false URL.', 'message' => 'Double check that URL! Is it correct?' } } docker-compose.yml for gitlab:
version: '3.7' services: gitlab: image: 'internal-docker-repo:1234/gitlab/gitlab-ce:11.8.3-ce.0' restart: always hostname: 'test' container_name: test volumes: - './config:/etc/gitlab:rw' networks: - net networks: net: external: true name: test-net Internally (to docker networks) nginx is known as nginx and gitlab is known as test. I have confirmed I can ping each container from inside the other, using their container names.
As it is now, it almost works. When I go to https://localhost/git/ on my linux host I get a 404 error page from gitlab, but no login screen.
I'm obviously missing something but I'm not sure what it is. It's hard for me to tell if it's an NGinx configuration issue or a Gitlab configuration issue.
Log output when I hit https://localhost/git/
nginx log output:
