How to setup Continous Integration for GitLab with Jenkins

Hi, I'd like to share with you how I got my Jenkins CI set up for my private GitLab projects. This is more like a sheet of notes of mine, but I hope it'll help someone as I haven't found any good tutorial for Jenkins+Gitlab on the web yet :D

Here we go:

• generate ssh keys on own server -> PUBLIC and PRIVATE ( no passphrase )
• go to GitLab profile settings -> SSH keys -> add PUBLIC ssh key to GitLab = this will allow your Jenkins server to access your GitLab
• also create full access GitLab API access token for Jenkins on your gitlab profile settings and keep it

---

• install Git + GitLab plugin on Jenkins ( make sure they are enabled (ticked) in Jenkins !!!)

1. (Optional) IP Addresses

Before we can start we're going to need the IP address (or the IP addresses) of your VPN so that we can whitelist those later on, write them down. They are obviously going to be different for every VPN and VPNs with multiple servers, so I'll leave this up to you.

2. Install UFW

On some systems UFW is installed and enabled by default (Ubuntu, for example). Installation procedure is going to be different for every distribution of GNU/Linux, but it's usually something like
