Docker on Debian 11 bare metal with gitlab-ci installed the "blessed" way (by adding gitlabs apt repos).

No optimisation to the baseOS other than mounting the /var/lib/docker on a RAID0 array with noatime on the volume and CPU mitigations disabled on the host

Compilation is mostly go binaries (with the normal stuff like go vet/go test).

Rarely it will do other things like commit-lint (javascript) or KICS/SNYK scanning.

the machines themselves are Dual EPYC 7313 w/ 256G DDR4.

Where do you keep your bare metal machines if I my ask? I wanted to do a similar setup a while ago (building/testing on Hetzner bare metal, deployments and the rest on AWS) but due to Amazon's pricing policy the cost of traffic would be enormous.

Not the person you asked, but we have something similar to what you described - our GitLab is self-hosted on Hetzner cloud and the build machine is a beefy bare metal machine in the same datacenter (plus an additional Mac in our office just for iOS). Built images are stored in GitLab repository and deployed from there.

We deploy to AWS (among others) and had no issues regarding traffic price since it's ingress into AWS.

We use Gitlab SaaS with our own CI runners on-prem (I have a small server room in the office).

I push our artefacts back to gitlab, and we deploy from gitlab's registry to google cloud (GKE).
