Establish a process for renewing TLS certs for the 2 webhook controllers
Open, Needs TriagePublic


The validating admission webhooks running in the new version of Toolforge Kubernetes use certs generated using the certificates API in Kubernetes. That implies an expiration of one year. They need to be renewed via an automated or manually reviewed process that can be reliably used without a deep dive into that API every time.

@aborrero set up a script for requesting certs at modules/toolforge/files/k8s/admin_scripts/ that places certs in a tmpdir. The main difference here is that we need them in a Kubernetes secret (which can easily be generated from the files like in their individual scripts) and to restart the services.

The services also could use some prometheus instrumentation to tell our monitors about when their certs expire.
