usage_description="
|
|
Find all Kubernetes API namespaced resource types and queries the current namespace for all of them
|
|
|
|
Useful to scan the current namespace for all resources since 'kubectl get all' only returns select API objects
|
|
|
|
Can set KUBECTL_GET_ALL_SEPARATOR environment variable, useful like this:
|
|
|
|
KUBECTL_GET_ALL_SEPARATOR='---' ${0##*/} --all-namespaces -o yaml > dump.yaml
|
|
|
|
Useful to be able to scan live Kubernetes objects with file linting tools like Pluto to detect deprecated live objects on the cluster affecting your Kubernetes cluster upgrades
|
|
|
|
|
|
Requires Kubectl to be installed and configured
