[Tailscale] is really good. I’ve been using it as a virtual private network to span 2 home networks and to securely (!) access my hosts when I’m remote. Recently Tailscale added Webhook functionality to permit processing subscribed-to (Tailscale) events. I’m always a sucker for a webhook ;-) Here’s a curl command to send a test event to a Tailscale Webhook: URL="" # From Tailscale's docs # https://tailscale.com/kb/1213/webhooks/#events-payload BODY=' [ { "timestamp": "2022-09-21T13:37:51.

I developed an admission webhook for Akri, twice (Golang, Rust). I naively followed other examples for the generation of the certificates, created a 1.20 cluster and broke that process. I’d briefly considered using cert-manager recently but quickly abandoned the idea thinking it would be onerous and unnecessary complexity for little-old-me. I was wrong. It’s excellent and I recommend it highly. I won’t reproduce the v1beta1 and v1 examples from the Stackoverflow question as they should be self-explanatory.

I spent some time last week writing my first admission webhook for Kubernetes. I wrote the handler in Golang because I’m most familiar with Golang and because, as Kubernetes’ native language, I was more confident that the necessary SDKs would exist and that the documentation would likely use Golang by default. I struggled to find useful documentation and so this post is to help you (and me!) remember how to do this next time!
