Editing Kubectl Plugins and Krew

[https://krew.sigs.k8s.io/ Krew] helps you discover and install kubectl plugins on your machine.

There are a lot of kubectl plugins you can install and use to enhance your Kubernetes experience.

'''Prerequisites:''' A recent copy of the '''git''' command (such as available from the IUS repo) must be installed for krew to operate.

Let’s get started:

1. Install and set up Krew on your machine and add krew's bin directory to your path

 (
  set -x; cd "$(mktemp -d)" &&
  OS="$(uname | tr '[:upper:]' '[:lower:]')" &&
  ARCH="$(uname -m | sed -e 's/x86_64/amd64/' -e 's/\(arm\)\(64\)\?.*/\1\2/' -e 's/aarch64$/arm64/')" &&
  KREW="krew-${OS}_${ARCH}" &&
  curl -fsSLO "https://github.com/kubernetes-sigs/krew/releases/latest/download/${KREW}.tar.gz" &&
  tar zxvf "${KREW}.tar.gz" &&
  ./"${KREW}" install krew
 )

 export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"

2. Download the plugin list:
 kubectl krew update
3. Discover plugins available on Krew:
 kubectl krew search
 NAME                            DESCRIPTION                                         INSTALLED
 access-matrix                   Show an RBAC access matrix for server resources     no
 advise-psp                      Suggests PodSecurityPolicies for cluster.           no
 auth-proxy                      Authentication proxy to a pod or service            no
 [...]
4. Choose a plugin from the list and install it:
 kubectl krew install access-matrix
5. Use the installed plugin:
 kubectl access-matrix
6. Keep your plugins up-to-date:
 kubectl krew upgrade
7. Uninstall a plugin you no longer use:
 kubectl krew uninstall access-matrix

This is pretty much all you need to know as a user to use Krew. Interesting plugins already installed and useful include:
