Kube-Janitor

Kubernetes Janitor cleans up (deletes) Kubernetes resources on (1) a configured TTL (time to live) or (2) a configured expiry date (absolute timestamp).

This chart helps you deploy kube-janitor as CronJob on your Kubernetes cluster. You can find the original repo here: https://github.com/hjacobs/kube-janitor

Configuration

The deployment option for this chart currently only support CronJob type. Please checkout Kubernete's docs for more info on CronJob's config options. You can check out more configuration examples on kube-janitor's own README for more of the package's options.

Some of the default values are not specified in the values.yaml and are instead inherited the default from upstream.
