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:
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/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/windows/amd64/kubectl.exe
Or, if you prefer, you can use Chocolatey to install:
choco install kubernetes-cli
How to Use
kubectl Plugins
Ever heard of krew? It's something you can use to manage kubectl plugins.
Installing krew
Use the following command:
(
set -x; cd "$(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:
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:
