kubectl-plugins

A collection of plugins for kubectl integration (for Kubectl versions >= 1.12.0)

A portion of these plugins are available on krew as well.

These plugins are for kubectl versions at or above 1.12.0 only. Check your version via kubectl version
For versions below 1.12.0, use the 1.11.0 branch.
To upgrade your kubectl version via homebrew: brew upgrade kubectl, or via gcloud: gcloud components update
The kubectl-ip plugin requires jq ( brew/apt/yum install jq )
All coding was written to maintain compatibility across both BSD and GNU.
Requires Bash.

Like kubectl exec, but offers a --user flag to exec as root (or any other user)
'ssh' is a misnomer (it works by mounting a docker socket as a volume), but it's easier to work with as a command.
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 ssh [OPTIONAL: -n <namespace>] [OPTIONAL: -u <user>] [OPTIONAL: -c <Container Name>] [REQUIRED: <PodName> ] -- [command]

Example: kubectl ssh -n default -u root -c prometheus prometheus-282sd0s2 -- bash

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

View current namespace: kubectl switch
Switch namespace: kubectl switch preprod
Switch cluster: kubectl switch cluster staging (accepts fuzzy on the cluster name)
List and select from all available clusters: kubeclt switch cluster -l

Option	Required	Description	Example
-l	N	List available clusters and prompts for selection. Can only be used when `cluster` is passed.	`kubNctl switch cluster -l`
-h	N	Show usage	`kubectl switch -h`

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

Search for Docker images
If you have a Google Container Registry, run kubectl image -c to set it as the default for future searches.
If not configured with -c, searches will use Docker Hub by default.
Adding -p will search Docker Hub, regardless of any default.
Sorts Docker Hub images by number of stars.
Sorts GCR images by upload date.

Example: kubectl image kafka

Outputs the node name, node IP, and Pod IP for a given resource. Search is performed against common labels (defaults to app, name, component)

Example: kubectl ip cassandra

Example: kubectl uptime
