This article will explain in detail what is the use of Krew in Kubernetes. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Concept

Krew is the package management tool for the kubectl plug-in. With Krew, you can easily use kubectl plugin: discover, install, and manage plug-ins. Use something like apt, dnf, or brew.

For kubectl users: krew helps users search, install, and manage kubectl plug-ins

For plug-in developers: krew can help you package and distribute plug-ins on multiple platforms.

Use

Use of krew:

Kubectl krew search # shows all plug-ins kubectl krew install view-secret # install the plug-in named view-secret kubectl view-secret # use the plug-in kubectl krew upgrade # to upgrade the installed plug-in kubectl krew remove view-secret # uninstall plug-in installation warning: krew is only compatible with kubectl v1.12 or later. MacOS and Linux

Confirm that git is installed.

Run the following command on the terminal to download and install krew: (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)

Add the $HOME/.krew/bin directory to the PATH environment variable. You can add the following to a .bashrc or zshr file:

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

Restart shell.

Windows

……

Verify installation

Run the kubectl plugin list command to view the installed plug-ins, which displays the running results of kubectl-krew. Now, you can try using the kubectl crew command.

Upgrade krew

Krew itself is also a "kubectl plug-in", so you can use the command kubectl krew upgrade command to upgrade krew.
