One of my recent tasks was to run an upgrade of a production PostgreSQL database. Since we have PostgreSQL running in a Docker container in our Hashicorp Nomad environment, I assumed it would be enough to switch to a new Docker image and everything would be working fine.
Recently, we've been running into a weird problem. After restarting 2 nodes in our Nomad cluster, we could not properly access GitLab via SSH anymore. Web access was working fine, also cloning via https:// worked, but not via SSH which is what most of our developers use by default.
Earlier this year we decided to test Renovate to manage automated dependency updates in our self-hosted GitLab environment. Being able to run Renovate in our own environment and configure it to our needs made a lot of sense. Since we run our internal tooling on a Nomad cluster, we had to configure a Nomad job for Renovate.
