Here is my install script to set up Ubuntu since it has a bit of extra steps for privileged ports https://gitlab.meme.beer/-/snippets/1

Docker compose example, note that my config has a shared network with containers in another compose called nginx to keep traffic inside docker.

The VM is a 6 thread 16gb

OS is currently Ubuntu 22.04.5 LTS (cloud image which is lightweight) just running a very simple docker engine install using the script (plus a few other options since I script the install)

The load averages as of this current moment are 0.12, 0.15, 0.10 so not even a full thread is being used.

I let the container run unmetered on the CPU and memory.

I can provide both the compose and my install script (which is on the GitLab instance) if you are curious.

Thanks! Super helpful and I’d love to have the compose and install script. I also looked into the Helm charts but still wondering if I should go down that route or not eventually.
