    PostgreSQL and Redis


Gitlab CE uses Redis to store user sessions and a task queue.
GitLab CE uses PostgreSQL as its database back end.

Start PostgreSQL Docker Container

docker run -d --name postgresql \
  -p 5432:5432 \
  -e POSTGRES_USER=gitlab \
  -e POSTGRES_PASSWORD=gitlab \
  -e POSTGRES_DB=gitlabhq_production \
  postgres:9.6.14
Install psql client for connecting to PostgreSQL

apt install postgresql-client-common postgresql-client-10

psql -h localhost -p 5432 -U gitlab -W gitlabhq_production
Start Redis Docker Container

docker run -d --name redis -p 6379:6379 redis:latest
Start Gitlab


Set the external_url to the URL that will be used by Gitlab.

docker run -d --name gitlab \
  -p 30080:30080 \
  -p  7999:22 \
  --env GITLAB_OMNIBUS_CONFIG="external_url 'http://gitlab.gestalts.net:30080'; gitlab_rails['gitlab_shell_ssh_port']=7999;" \
  --link postgresql \
  --link redis \
  gitlab/gitlab-ce:latest
Connect to Gitlab and create a root username password
