I am trying to delete multiple ConfigMaps at once using a label. With kubectl, I would do it as follow:

kubectl delete cm -l application=my-app

Kubeclient offers the delete_config_map method, but it requires a name.

# `k` is an instance of Kubeclient::Client
k.delete_config_map('my-config-map')

Is there a way to acheive the same behavior as the CLI here?

CodePudding user response：

The way kubectl does operations upon labeled, versus named, resources is that it actually does that in two phases: get -o name $resourceType -l ... and then the actual requested operation upon ${those_resource_names}

One can run kubectl --v=10 (or the v of your choice) to see it in action

Since that behavior is a feature of kubectl and not the kubernetes API itself, it means anyone trying to replicate that handy feature will need to replicate the two-phase approach also
