Add a way to print the current kubectl command argument string in a reusable way for kuberctl #1748
Description
What would you like to be added:
I want to add a feature to kubectl that outputs a command-line string capable of reproducing the current execution context of a kubectl command in environments where kuberc is not configured, effectively replicating the functionality currently provided by kuberc.
Why is this needed:
In Kubernetes, SREs sometimes share kubectl command snippets within their teams to consistently verify the state of clusters and applications.
Example
## Check running specific production pods
$ kubectl get po -n app-01 --field-selector status.phase=Running -l environment=production
However, as kuberctl becomes more widely used, individual kubectl command snippets may become unshareable. Therefore, it would be beneficial to have a method to share requests made by kubectl even without kuberc configuration.
Design Proposal:
## kuberc
apiVersion: kubectl.config.k8s.io/v1alpha1
kind: Preference
aliases:
- name: getdbprod
command: get
prependArgs:
- pods
flags:
- name: labels
default: what=database
- name: namespace
default: us-2-production
overrides:
- command: apply
flags:
- name: server-side
default: "true"
- command: delete
flags:
- name: interactive
default: "true"
snippetOutput: true ## example
Example output
$ KUBECTL_KUBERC=true kubectl getdbprod
## Execute: $ kubectl get pods -l what=database -n us-2-production
...
$ KUBECTL_KUBERC=true kubectl apply -f -
## Execute: $ kubectl apply --server-side=true -f -
...
