kubectl Install
Ready to get kubectl onto your machine? You've come to the right place.
How to Install
For OSX Users
Option one: You can get kubectl on to your OSX machine with one command using Homebrew:
brew install kubectl
Option two: Feel like using curl
instead? No problem:
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl
For Linux Users
Just input the following command:
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
For Windows Users
Command one, for good measure:
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/windows/amd64/kubectl.exe
Or, if you prefer, you can use Chocolatey to install:
choco install kubernetes-cli

kubectl Plugins
Ever heard of krew? It's something you can use to manage kubectl plugins.
krew is a handy tool that lets you manage kubectl plugins, sort of like apt or yum. It allows you to search for, install, and manage kubectl plugins.
Installing krew
Use the following command:
(
set -x; cd "$(mktemp -d)" &&
curl -fsSLO "https://storage.googleapis.com/krew/v0.2.1/krew.{tar.gz,yaml}" &&
tar zxvf krew.tar.gz &&
./krew-"$(uname | tr '[:upper:]' '[:lower:]')_amd64" install \
--manifest=krew.yaml --archive=krew.tar.gz
)
Once you've got it installed, add the krew binary to your PATH:
export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"
Then, you should be able to verify your install with a kubectl command:
$ kubectl plugin list
The following kubectl-compatible plugins are available:
/home/<user>/.krew/bin/kubectl-krew
How to Use krew
Before your first use, update the plugin index using the following command:
kubectl krew update
Here's how you can use krew:
kubectl krew search # show all plugins
kubectl krew install ssh-jump # install a plugin named "ssh-jump"
kubectl ssh-jump # use the plugin
kubectl krew upgrade # upgrade installed plugins
kubectl krew remove ssh-jump # uninstall a plugin
After you install your plugins, you'll see a list of external tools that the plugin depends on. You'll need to install these manually.
Installing plugin: ssh-jump
CAVEATS:
