New page

'''GitLab''' is a web-based [[DevOps]] lifecycle tool that provides a [[Git]]-repository manager providing wiki, issue-tracking and CI/CD pipeline features, using an open-source license, developed by GitLab Inc.

==Fix Let's Encrypt errors==

If after running <code>gitlab-ctl reconfigure</code> you see an error that looks like the following:
<pre>
Acme::Client::Error::Malformed: Method not allowed
</pre>

Below are the steps I use to fix it:

* Edit the <code>/etc/gitlab/gitlab.rb</code> file and disable '''https''' <code>external_url</code> and <code>letsencrypt</code> settings:
<pre>
external_url 'http://domain.com'
#external_url 'https://domain.com'
# letsencrypt['auto_renew'] = true
# letsencrypt['auto_renew_hour'] = 0
# letsencrypt['auto_renew_minute'] = nil # Should be a number or cron expression, if specified.
# letsencrypt['auto_renew_day_of_month'] = "*/4"
</pre>

* Then reconfigure gitlab:
<pre>
$ sudo gitlab-ctl reconfigure
</pre>

* Upgrade gitlab to the latest version:
<pre>
$ sudo apt update -y && sudo apt upgrade -y
</pre>

* Edit the <code>/etc/gitlab/gitlab.rb</code> file again and uncomment <code>https/letsencrypt</code> settings:
<pre>
external_url 'http://domain.com'
external_url 'https://domain.com'
letsencrypt['auto_renew'] = true
letsencrypt['auto_renew_hour'] = 0
letsencrypt['auto_renew_minute'] = nil # Should be a number or cron expression, if specified.
letsencrypt['auto_renew_day_of_month'] = "*/4"
</pre>

* Renew the certs and reconfigure (note: you may have to reconfigure one more time for the certs):
<pre>
$ sudo gitlab-ctl reconfigure
$ sudo gitlab-ctl restart redis
$ sudo gitlab-ctl renew-le-certs
$ sudo gitlab-ctl gitlab-ce reconfigure
</pre>

And now we are running the latest version of gitlab-ce and the certs have been renewed.

==Miscelleanous==

* Reset root password:
<pre>
$ cat << EOF >reset_root_passwd.sh
#!/bin/bash

gitlab-rails runner -e production " \
user = User.find_by(id: 1);
user.password = user.password_confirmation = '<MY_NEW_PASSWORD>'; \
user.save!"
EOF
</pre>
