Error: Cannot continue without a database

I am using RancherOS v1.0.3. I am trying to install separate GitLab and PostgreSQL container on Kubernetes. Right now, i am only trying to run single instance of each container.

[rancher@rancher-agent-1 ~]$ cat postgresql.sh
docker run --name gitlab-postgresql -d \

docker run --name gitlab -d --link gitlab-postgresql:postgresql \
    --volume /srv/docker/gitlab/gitlab:/home/git/data \
    sameersbn/gitlab:9.4.5

I started PostgreSQL first and then GitLab.

But when i try connecting to the db, i see that the given database and user is there. Not sure what needs to be configured. Is there something wrong with the --link thing?

[rancher@rancher-agent-1 ~]$ docker exec -it gitlab-postgresql bash

Do i need to launch a redis container too or GitLab container has the default in-built? I have implemented only the following section: https://github.com/sameersbn/docker-gitlab#linking-to-postgresql-container.

Sorry for the confusion but i got it working. Redis was indeed required but yesterday when i was checking the logs, it was only complaining about the db issue. Today when i started the Google Cloud instance and checked for error again, it was surprisingly showing no issue with database and started showing issue with redis as shown below:

...

Configuring gitlab::database
Configuring gitlab::redis
ERROR:
  Please configure the redis connection.
  Refer http://git.io/PMnRSw for more information.

Then when i configured Redis and provided values to GITLAB_SECRETS_DB_KEY_BASE, GITLAB_SECRETS_SECRET_KEY_BASE and GITLAB_SECRETS_OTP_KEY_BASE, i was finally able to access the GitLab UI. :)
