module KubectlClient::Wait

Overview

Using sleep() to wait for terminating resources is unreliable.

1. Resources still in terminating state can interfere with test runs. and result in failures of the next test (or spec test).

2. Helm uninstall wait option and kubectl delete wait options, do not wait for child resources to be fully deleted.

3. The output from kubectl json does not clearly indicate when a resource is in a terminating state. To wait for uninstall, we can use the app.kubernetes.io/name label, to lookup resources belonging to a CNF to wait for uninstall. We only use this helper in the spec tests, so we use the "kubectl get" output to keep things simple.
