My configuration

`docker run --name gitlab-postgresql -d
--env 'DB_NAME=gitlabhq_production'
--env 'DB_USER=gitlab' --env 'DB_PASS=password'
--env 'DB_EXTENSION=pg_trgm'
--volume /share/CACHEDEV1_DATA/VM/container-station-data/gitlab/postgresql:/var/lib/postgresql
sameersbn/postgresql:9.5-3

docker run --name gitlab-redis -d
--volume /share/CACHEDEV1_DATA/VM/container-station-data/gitlab/redis:/var/lib/redis
sameersbn/redis:latest

docker run --name gitlab -d
--link gitlab-postgresql:postgresql --link gitlab-redis:redisio
--publish 10022:22 --publish 10080:80
--env 'GITLAB_PORT=10080' --env 'GITLAB_SSH_PORT=10022'

Start by reviewing the PostgreSQL and GitLab docker run commands in the issue, especially DB_NAME, DB_USER, DB_PASS, the linked container name, and the mounted data directory. Compare those settings with the PostgreSQL container logs showing user creation, then reproduce the startup sequence and determine whether the authentication failure is caused by configuration or persisted database state. Done means the documented configuration starts GitLab successfully or the issue is closed with confirmed setup requirements.
