Installation

For macOS:

🎉 kubectx is now in Homebrew! 🎊

Use the Homebrew package manager:

brew install kubectx

this will also set up bash/zsh completion scripts automatically.

Running brew install with --with-short-names will install tools with names kctx and kns to prevent prefix collision with kubectl name.

Note: If you installed kubectx before it was accepted to Homebrew core repository, reinstall with: brew untap ahmetb/kubectx && brew uninstall --force kubectx && brew update && brew install kubectx

Other platforms:

• Download the kubectx script
• Add it somewhere in your PATH
• Make it executable (chmod +x)
• You can also install bash/zsh completion scripts manually.
