Schedule Builder
This simple tool has the objective to parse and update the following YAML files located in k/website:
- https://github.com/kubernetes/website/blob/main/data/releases/schedule.yaml
- https://github.com/kubernetes/website/blob/main/data/releases/eol.yaml
Those show the scheduled and past patch releases of the current Kubernetes Release cycle as well as Kubernetes Release Cycles schedules in machine readable format.
Install
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.
Usage
Assuming you have cloned the k/website and k/release repositories, like:
.
+-- k8s.io
| +-- release
| +-- website
Updating schedule.yaml and eol.yaml
To update both files, run:
schedule-builder -uc ../website/data/releases/schedule.yaml -e ../website/data/releases/eol.yaml
The output should look similar to this:
INFO Validating options
INFO Reading schedule file: ../website/data/releases/schedule.yaml
INFO Parsing schedule
INFO Updating schedule
INFO Using existing upcoming release for 2024-05-14
INFO Using existing upcoming release for 2024-06-11
INFO Using existing upcoming release for 2024-07-09
INFO Got 3 new upcoming releases, not adding any more
INFO Writing end of life branches: ../website/data/releases/eol.yaml
INFO Wrote schedule YAML to: ../website/data/releases/schedule.yaml
You can now propose the changeset as a new k/website PR for further review.
For Patch Release Schedule
schedule-builder --config-path ../website/data/releases/schedule.yaml --type patch
The output will be something similar to this
