Question

I already run a gitlab server inside a docker container with an external nginx server inside an other docker container, so the gitlab nginx server is deactivated. Now I want

I also had the same problem like you and got it to work with the following:

Nginx:

## Lines starting with two hashes (##) are comments with information.
## Lines starting with one hash (#) are configuration parameters that can be uncommented.

## Redirects all HTTP traffic to the HTTPS host
server {
  listen *:80;
  server_name  registry.project-oc.de;
  server_tokens off; ## Don't show the nginx version number, a security best practice
  return 301 https://$http_host:$request_uri;
  access_log  /var/log/nginx/gitlab_registry_access.log;
  error_log   /var/log/nginx/gitlab_registry_error.log;
}

server {
  # If a different port is specified in https://gitlab.com/gitlab-org/gitlab-ce/blob/8-8-stable/config/gitlab.yml.example#L182,
  # it should be declared here as well
  listen *:443 ssl http2;
  server_name  registry.project-oc.de;
  server_tokens off; ## Don't show the nginx version number, a security best practice

  client_max_body_size 0;
  chunked_transfer_encoding on;

    proxy_pass          http://localhost:5000;
  }
}

gitlab.rb

registry_external_url 'https://registry.project-oc.de'
registry_nginx['listen_port'] = 5000
gitlab_rails['registry_enabled'] = true
registry_nginx['enable'] = false
registry['enable'] = true

After editing the both files you have to restart nginx and gitlab
