or you can build all images using all-in-one Dockerfile.

docker build --file all-in-one/Dockerfile --rm -t genshen/gitlab-ce .
docker build --file gitlab-pages/Dockerfile --rm -t genshen/gitlab-pages .

For currently, only postgresql is supported.

In docker compose, 127.0.0.1 (and its reserved DNS name localhost) always refers to the current container, never the host. So, in database config (file config/database.yml), the host term should set to postgresql container name. So is the redis server hostname.

In entrypoint of this gitlab image, the path of file .gitlab_workhorse_secret is set to be ${GITLAB_WORKHORSE_DIR}/.gitlab_workhorse_secret (${GITLAB_WORKHORSE_DIR} is usually /home/git/gitlab-workhorse).
if .gitlab_workhorse_secret file path is not configured correctly, the clone will return http 500 error when using http(s) protocol.
You should also config .gitlab_workhorse_secret file path in workhorse.secret_file in config file config/gitlab.yml.

The symbolic link of following directories are created to ${GITLAB_DATA_DIR}, ${GITLAB_LOG_DIR} or ${GITLAB_CONFIG_DIR}.

default, ${GITLAB_HOME} is /home/git; ${GITLAB_DIR} is ${GITLAB_HOME}/gitlab; ${GITLAB_PAGES_DATA_DIR} is /gitlab/gitlab-pages, ${GITLAB_DATA_DIR} is /gitlab/data.

Run docker-compose up command, the gitlab-workhorse will listen on tcp port 8181. You can also change environment variable WORKHORSE_LISTEN_NETWORK to "unix" (default value is "tcp") to let gitlab-workhorse listen unix socket ${GITLAB_DATA_DIR}/tmp/sockets/gitlab.socket.

Image genshen/gitlab-ce does not containe gitlab-pages. If you need gitlab-pages, you can pull genshen/gitlab-pages. You should then follow this link to config your gitlab-pages.
