Setting up Gitlab with a Managed Database for PosgreSQL
GitLab is an open-core Git-repository manager providing a Wiki, Issue-Tracking and CI/CD pipeline features. Open-core means that the core functionalities of the software are released under an open-source licence with added optional modules. The tool is used by many large technology companies to manage their software development life cycle. The tool was initially developed in Ruby and uses in the current technology stack also Go and Vue.js.

Connect yourself to your instance using SSH
aptpacket cache and upgrade the software already installed on the instance:
apt update && apt upgrade -y
Install the following packages using

Replace the following values in the configuration:
<SCALEWAY_DATABASE_BASE>: The name of your Scaleway Elements Database. It is recommended to use a name like
<SCALEWAY_DATABASE_IP>: The IP address of your Scaleway Elements Database Instance

<SCALEWAY_DATABASE_USERNAME>: Your Scaleway Elements Database user
<SCALEWAY_DATABASE_PASSWORD>: Password of your Scaleway Elements Database user
