Kubernetes Deployment Cleaner

Very simple script to delete all expired deployments after they pass their annotated expiration time.

In our continuous integration (aka c20n) environment, we wish to have the deployments be deleted after about 4 hours. We annotated these ephemeral deployments with a key deploymentExpirationTime that contains a value four hours in the future, like 2018-07-19T16:29:38Z.

Building the Docker image:

    $ make

Deploying:

    $ kubectl apply -f deploy/

There are a few options:

• --dry-run - Do not actually remove any deployments, only print what would be done

Credit Where Credit is Due

This code was very lightly modified from kube-job-cleaner (aka rip off).
