This simple tool has the objective to parse the yaml file located in k/website, which shows the scheduled and past patch releases of the current Kubernetes Release cycle as well as Kubernetes Release Cycles schedules (like 1.23) in machine readable format.
The simplest way to install the schedule-builder CLI is via go install:
$ go install k8s.io/release/cmd/schedule-builder@latest
This will install schedule-builder to $(go env GOPATH)/bin/schedule-builder.
Also if you have the kubernetes/release cloned you can run the make release-tools to build all the tools.
To run this tool you can just do, assuming you have cloned both website and release repositories, like
.
+-- k8s.io
| +-- release
| +-- website
$ schedule-builder --config-path ../website/data/releases/schedule.yaml --type patchThe output will be something similar to this
