kubectl completion

Synopsis

Output shell completion code for the specified shell (bash, zsh, fish, or powershell). The shell code must be evaluated to provide interactive completion of kubectl commands. This can be done by sourcing it from the .bash_profile.

Detailed instructions on how to do this are available here:

  1. for macOS:
  2. https://kubernetes.io/docs/tasks/tools/install-kubectl-macos/#enable-shell-autocompletion
  3. for linux:
  4. https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/#enable-shell-autocompletion
  5. for windows:
  6. https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/#enable-shell-autocompletion

Note for zsh users: [1] zsh completions are only supported in versions of zsh >= 5.2.

Examples

  1. # Installing bash completion on macOS using homebrew
  2. ## If running Bash 3.2 included with macOS
  3. brew install bash-completion
  4. ## or, if running Bash 4.1+
  5. brew install bash-completion@2
  6. ## If kubectl is installed via homebrew, this should start working immediately
  7. ## If you've installed via other means, you may need add the completion to your completion directory
  8. kubectl completion bash > $(brew --prefix)/etc/bash_completion.d/kubectl
  9. # Installing bash completion on Linux
  10. ## If bash-completion is not installed on Linux, install the 'bash-completion' package
  11. ## via your distribution's package manager.
  12. ## Load the kubectl completion code for bash into the current shell
  13. source <(kubectl completion bash)
  14. ## Write bash completion code to a file and source it from .bash_profile
  15. kubectl completion bash > ~/.kube/completion.bash.inc
  16. printf "
  17. # kubectl shell completion
  18. source '$HOME/.kube/completion.bash.inc'
  19. " >> $HOME/.bash_profile
  20. source $HOME/.bash_profile
  21. # Load the kubectl completion code for zsh[1] into the current shell
  22. source <(kubectl completion zsh)
  23. # Set the kubectl completion code for zsh[1] to autoload on startup
  24. kubectl completion zsh > "${fpath[1]}/_kubectl"
  25. # Load the kubectl completion code for fish[2] into the current shell
  26. kubectl completion fish | source
  27. # To load completions for each session, execute once:
  28. kubectl completion fish > ~/.config/fish/completions/kubectl.fish
  29. # Load the kubectl completion code for powershell into the current shell
  30. kubectl completion powershell | Out-String | Invoke-Expression
  31. # Set kubectl completion code for powershell to run on startup
  32. ## Save completion code to a script and execute in the profile
  33. kubectl completion powershell > $HOME\.kube\completion.ps1
  34. Add-Content $PROFILE "$HOME\.kube\completion.ps1"
  35. ## Execute completion code in the profile
  36. Add-Content $PROFILE "if (Get-Command kubectl -ErrorAction SilentlyContinue) {
  37. kubectl completion powershell | Out-String | Invoke-Expression
  38. }"
  39. ## Add completion code directly to the $PROFILE script
  40. kubectl completion powershell >> $PROFILE
