Write script to reset GitLab Root pw inside docker

[a-t-0]

Why: Sometimes a user may forgot a GitLab password without wanting to make and restore a complete backup of the server in a fresh GitLab server installation.

search for your Docker CONTAINER_ID

docker ps -all

eg

docker exec -it d0bbe0e1e3db bash <-- with your CONTAINER_ID

$ gitlab-rails console -e production

user = User.where(id: 1).first
user.password = 'your secret'
user.password_confirmation = 'your secret'
user.save
exit

      <p>After you type the <code>gitlab-rails..</code> command, you wait until you see the <code>:0&gt;</code> and then you start typing, and enter for each line. It will also give some output inbetween, like:</p>
