Welcome to TGIK!

This week Kris will be looking at Kubebuilder, a framework for building Kubernetes APIs using custom resource definitions (CRDs).

The Week in Review

• Clusterctl release - part of SIG Cluster Lifecycle. Example of how folks are thinking of deploying clusters in a standardized way.
  • https://github.com/kubernetes-sigs/cluster-api/issues/383
• GPUs go GA on GKE
  • Check out Kris' talk with Dave Aronchik showing off Kubeflow
• The History of Kubernetes
• Scaling Kubernetes to 25m users
• AWS Cost Savings by Utilizing Kubernetes Ingress with Classic ELB
• KubeIP

Kubebuilder

Part of SIG Cluster lifecycle / Cluster API.

Starting with main.go.

Installing Kubebuilder

Do not use go get, grab the tarball for your system.

• There's a book with getting started documentation. We're following the quickstart section.
• You'll end up with it in /usr/local/kubebuilder/bin
• Using GOOS and GOARCH (@krisnova mentions a video from Rob Pike on this, anyone have a link?)
