In that case Debian, Ubuntu, and Windows server should absolutely dwarf OSX…

That said, I personally wouldn’t consider “server use” to be “mainstream”… To me install-base does not equate to “mainstream”.

Shouldn’t Ubuntu be more “mainstream” than debian?

All my docker images are in code in Github.

Renovate makes a PR when there are image or helm chart updates.

ArgoCD sees the PR merge and applies to Kubernetes.

For a few special cases I use ArgoCD-image-updater.

Well… Canada has a land border with Denmark…

I have my Firefox configured to force HTTPS, so it’s rather inconvenient to work with any non-HTTPS sites.

Because of that I decided to make my own CA. But since I’m running in Kubernetes and using cert-manager for certs, this was really easy. Add a resource for a self-singed issuer, issue a CA cert, then create an issuer based on that CA cert. 3 Kubernetes resources total: https://cert-manager.io/docs/configuration/ca/ and finally import the CA cert on your various devices.

However this can also be done using LetsEncrypt, with the DNS01 challenge. That way you don’t need to expose anything to the Internet, and you don’t need to import a CA on all of your devices. Any cert you issue will however appear in certificate transparency logs. So if you don’t want anyone to know that you are running a Sonarr instance, you shouldn’t issue a certificate with that in it’s name. A way around that is a wildcard cert. Which you can then apply to all your subservices without exposing the individual service in logs. The wildcard will still be visible in the logs though…
