Create a new directory and save the above file inside it as docker-compose.yml. You’ll need to replace the field hostname with the external URL that you’ll use to access your Gitlab instance.

mkdir gitlab
vi gitlab\docker-compose.yml

Run docker-compose up -d to fetch the images from the docker hub and create your Gitlab instance. You’ll be able to access Gitlab from a browser on port 8000 and the SSH on port 8822.


Gitlab Runner Error: sudo: no tty present and no askpass program specified

Get Social!

After issuing the first build on a dynamically created Container I came across the following build error when running a command with sudo.

sudo: no tty present and no askpass program specified

The error is caused by trying to run a command with sudo, however the calling user has not been authorised to use sudo. The error isn’t helpful, and doesn’t really spell out where to go, but adding the calling user to the sudoers file will save the day.

Solution

Open up the sudoers file for editing in your favorite editor.

vi /etc/sudoers

And add your gitlab runner user to the bottom. If you installed your gitlab runner from the official apt repositories then your gitlab-runner process will run under the gitlab-runner user.

Add the following to the bottom of the file:

gitlab-runner ALL=(ALL) NOPASSWD: ALL

Retry your build and you should be back in business!
