From a fresh install of GitLab, here’s what I did:
I wanted to run GitLab Mattermost at “https://mattermost.secretbank.org”. I created an A record that pointed to the IP of my GitLab instance.
Per the getting started docs, I then added this line to gitlab.rb:
mattermost_external_url 'https://mattermost.secretbank.org'
Now, gitlab-ctl reconfigure
https://mattermost.secretbank.orgUse this get-gitlab-mattermost-version.sh snippet.
