Kustomize

Selfhosting multiple applications often means having to deal with disparate user accounts unless you can integrate them with a common third party. A tried and tested framework for this is the ubiquitous LDAP, or Lightweight Directory Access Protocol, server.

I use Argo CD to maintain my Homelab as I find it intuitive. The nice GUI also helps me to quickly inspect problems which might occur when I try something fancy. Another widely used alternative is Flux CD which solves the same problem of GitOps-ing your cluster, but I have little experience with it yet.
