Set up IKEv2 VPN on a Mikrotik Router


I got rid of my AT&T router a few days back and managed to have a Mikrotik router hAP ac² as an alternative.

I have very slow traffic when using the AT&T home network when visiting some websites, e.g., weibo, so I want to route them via a VPN running on oracle cloud.

Docker hub by default only provides 1 private repo for normal users, which is clearly not what I want. So I decided to build my own docker registry and deploy it as a service in my home lab machine.
