SRE, chaotic good. Interested in K8s, KCP, Control planes.
On Thursday, Marvin and I will talk about Dynamic Multi-Cluster Controllers With Controller-runtime. Within sig-multicluster we are working on http://github.com/kubernetes-sigs/multicluster-runtime, an extension of controller-runtime to write controllers that talk to many clusters.

Whatever you want to define what something is (HELM TEMPLATE, kcl run, timoni build -> "yaml") push the desire state in Git,

it's not without irony that I have two Kubernetes-native solutions connected and reconciling without a Kubernetes cluster/distro running. Just two binaries on my laptop.

CLI commands using kind to start a kubernetes cluster. - go install sigs.k8s.io/kind@v0.25.0 - kind --version - $(go env GOPATH)/bin/kind build node-image v1.32.0-rc.0 - kind create cluster --image kindest/node:latest - kubectl --version
The @kubernetes.io Release team minted the v1.32.0 RC0 artifacts just now. Can you please kick the tires and create issues if you see any problems? Thanks!
Pretty handy to quickly start a kind cluster with the artifacts from:

We found three safety and two liveness issues in Bufstream 0.1.0, including the loss of acknowledged writes in healthy clusters. These problems were resolved by version 0.1.3 [β¦]

This is for those building Kube APIs, in @crossplane_io or any CRD. @_surbaniak and I will dive into Kube API evolution. What's the mental model, which patterns work, which don't.
No rants how bad or hard it is. Pure knowledge to navigate the domain.

From all the #Kubernetes enhancement proposals which one you are most excited about?
For me it's KEP-3962 where mutating admission policies can be defined with CEL expressions. This completes the validating admission work and gives us a fully-featured policy engine π
