kubectl krew remove exec-as

To remove the prompt plugin:

kubectl krew remove prompt
ex '+g/function kubectl()/d' -cwq ~/.bash_profile
ex '+g/KUBECTL_\(.*\)_PROMPT/d' -cwq ~/.bash_profile

kubectl exec-as

• Like kubectl exec, but offers a --user flag to exec as root (or any other user)
• Works by mounting a docker socket as a volume
• You must be in the same namespace as the target pod or you can use -n namespace option to specify the namespace
• Kudos to mikelorant for thinking of the docker socket! :)

Usage: kubectl exec-as [OPTIONS] <pod name> [-- <commands...>]

Option	Required	Description	Example
-h	N	Show usage	kubectl exec-as -h
-d	N	Enable debug mode. Print a trace of each commands	kubectl exec-as -d kafka-0
-n	N	The namespace scope for this CLI request	kubectl exec-as -n infra kafka-0
-u	N	User to exec as. Defaults to root	kubectl exec-as -u kafka kafka-0
-c	N	Specify container within pod	kubectl exec-as -c burrow-metrics kafka-0
--	N	Pass an optional command. Defaults to /bin/sh	kubectl exec-as kafka -- ls /etc/burrow

kubectl prompt

• Displays a warning prompt when issuing commands in a flagged cluster or namespace
• Commands that trigger the prompt include create, scale, delete, apply, etc.,

Start by flagging environments to prompt on:

• Flag a namespace: kubectl prompt add -n production
• Flag a cluster: kubectl prompt add -c my-cluster
• List flagged environments: kubectl prompt list
• Clear flagged environments: kubectl prompt remove
