Cannot make request to gitlab running in the official Docker container

Question

I am trying to run gitlab from a Docker (gitlab/gitlab-ce, latest) container using the instruction given here.

Docker version

Docker version 1.12.4, build 1564f02

I first run

docker run --detach --hostname <myIP> --publish 8000:443--publish 8001:80 --publish 8002:22 --name gitlab --restart always --volume /docker/app/gitlab/config:/etc/gitlab --volume /docker/app/gitlab/logs:/var/log/gitlab --volume /docker/app/gitlab/data:/var/opt/gitlab gitlab/gitlab-ce:latest

Then I edited the container's /etc/gitlab/gitlab.rb to set

external_url 'http://<myIP>:8001'
gitlab_rails['gitlab_shell_ssh_port'] = 8002

Then I restarted the container with

docker restart gitlab

Now.

When I try to connect to <myIP>:8001 I get a (110) Connection timed out.

When I try from the Docker container's host I get

xxx@xxx:~$ curl localhost:8001
curl: (56) Recv failure: Connection reset by peer

I cannot find what is wrong. Anybody can help ?

Answer 1

Here is a docker-compose.yml which worked fine for me

version: '2'
services:
  gitlab:
    image: gitlab/gitlab-ce:latest
    ports:
      - "8002:22"
      - "8000:8000"
      - "8001:443"
    environment:
      - "GITLAB_OMNIBUS_CONFIG=external_url 'http://192.168.33.100:8000/'"
    volumes:
      - ./config:/etc/gitlab
      - ./logs:/var/log/gitlab
      - ./data:/var/opt/gitlab

The thing is that when you configure external url as <MyIP>:8000 the listening port inside the container also is updated to 8000. In your case you are mapping port 8000 to 80 and you should be mapping 8000 to 8000 only

Read the below url for details on the same

https://docs.gitlab.com/omnibus/settings/nginx.html#setting-the-nginx-listen-port

If you need to override this port then you can do that in gitlab.rb

nginx['listen_port'] = 8081

I prefer to launch Gitlab using a docker-compose file instead of commands, as it is easy to configure, start, restart gitlab
