"content": "# `kubectx` + `kubens`: Power tools for kubectl\n\n\n\n\n[/badge.svg)](https://github.com/ahmetb/kubectx/actions?query=workflow%3A\"Go+implementation+(CI)\")\n\n\nThis repository provides both `kubectx` and `kubens` tools.\n[Install →](#installation)\n\n## What are `kubectx` and `kubens`?\n\n**kubectx** is a tool to switch between contexts (clusters) on kubectl\nfaster.
\n**kubens** is a tool to switch between Kubernetes namespaces (and\nconfigure them for kubectl) easily.\n\nHere's a **`kubectx`** demo:\n\n\n...and here's a **`kubens`** demo:\n\n\n### Examples\n\n```sh\n# switch to another cluster that's in kubeconfig\n$ kubectx minikube\nSwitched to context \"minikube\".\n\n# switch back to previous cluster\n$ kubectx -\nSwitched to context \"oregon\".\n\n# start an \"isolated shell\" that only has a single context\n$ kubectx -s minikube\n\n# rename context\n$ kubectx dublin=gke_ahmetb_europe-west1-b_dublin\nContext \"gke_ahmetb_europe-west1-b_dublin\" renamed to \"dublin\".\n\n# change the active namespace on kubectl\n$ kubens kube-system\nContext \"test\" set.\nActive namespace is \"kube-system\".\n\n# go back to the previous namespace\n$ kubens -\nContext \"test\" set.\nActive namespace is \"default\".\n\n# change the active namespace even if it doesn't exist\n$ kubens not-found-namespace --force\nContext \"test\" set.\nActive namespace is \"not-found-namespace\".\n---\n$ kubens not-found-namespace -f\nContext \"test\" set.\nActive namespace is \"not-found-namespace\".\n```\n\nIf you have [`fzf`](https://github.com/junegunn/fzf) installed, you can also\n**interactively** select a context or cluster, or fuzzy-search by typing a few\ncharacters. To learn more, read [interactive mode →](#interactive-mode)\n\nBoth `kubectx` and `kubens` support Tab completion on bash/zsh/fish\nshells to help with long context names. You don't have to remember full context\nnames anymore.\n\n-----\n\n## Installation\n\n| Package manager | Command |\n|---|---|\n| [Homebrew](https://brew.sh/) (macOS & Linux) | `brew install kubectx` |\n| [MacPorts](https://www.macports.org) (macOS) | `sudo port install kubectx` |\n| apt (Debian/Ubuntu) | `sudo apt install kubectx` |\n| pacman (Arch Linux) | `sudo pacman -S kubectx` |\n| [Chocolatey](https://chocolatey.org/) (Windows) | `choco install kubens kubectx` |\n| [Scoop](https://scoop.sh/) (Windows) | `scoop bucket add main && scoop install main/kubens main/kubectx` |\n| [winget](https://learn.microsoft.com/en-us/windows/package-manager/) (Windows) | `winget install --id ahmetb.kubectx && winget install --id ahmetb.kubens` |\n| [Krew](https://github.com/kubernetes-sigs/krew/) (kubectl plugin) | `kubectl krew install ctx && kubectl krew install ns` |\n\nAlternatively, download binaries from the [**Releases page →**](https://github.com/ahmetb/kubectx/releases) and add them to somewhere in your `PATH`.\n\n\nShell completion scripts
\n\n#### zsh (with [antibody](https://getantibody.github.io))\n\nAdd this line to your [Plugins File](https://getantibody.github.io/usage/) (e.g.\n`~/.zsh_plugins.txt`):\n\n```\nahmetb/kubectx path:completion kind:fpath\n```\n\nDepending on your setup, you might or might not need to call `compinit` or\n`autoload -U compinit && compinit` in your `~/.zshrc` after you load the Plugins\nfile. If you use [oh-my-zsh](https://github.com/ohmyzsh/ohmyzsh), load the\ncompletions before you load `oh-my-zsh` because `oh-my-zsh` will call\n`compinit`.\n\n#### zsh (plain)\n\nThe completion scripts have to be in a path that belongs to `$fpath`. Either\nlink or copy them to an existing folder.\n\nExample with [`oh-my-zsh`](https://github.com/ohmyzsh/ohmyzsh):\n\n```bash\nmkdir -p ~/.oh-my-zsh/custom/completions\nchmod -R 755 ~/.oh-my-zsh/custom/completions\nln -s /opt/kubectx/completion/_kubectx.zsh ~/.oh-my-zsh/custom/completions/_kubectx.zsh\nln -s /opt/kubectx/completion/_kubens.zsh ~/.oh-my-zsh/custom/completions/_kubens.zsh\necho \"fpath=($ZSH/custom/completions $fpath)\" >> ~/.zshrc\n```\n\nIf completion doesn't work, add `autoload -U compinit && compinit` to your\n`.zshrc` (similar to\n[`zsh-completions`](https://github.com/zsh-users/zsh-completions/blob/master/README.md#oh-my-zsh)).\n\nIf you are not using [`oh-my-zsh`](https://github.com/ohmyzsh/ohmyzsh), you\ncould link to `/usr/share/zsh/functions/Completion` (might require sudo),\ndepending on the `$fpath` of your zsh installation.\n\nIn case of errors, calling `compaudit` might help.\n\n#### bash\n\n```bash\ngit clone https://github.com/ahmetb/kubectx.git ~/.kubectx\nCOMPDIR=$(pkg-config --variable=completionsdir bash-completion)\nln -sf ~/.kubectx/completion/kubens.bash $COMPDIR/kubens\nln -sf ~/.kubectx/completion/kubectx.bash $COMPDIR/kubectx\ncat << EOF >> ~/.bashrc\n\n\n#kubectx and kubens\nexport PATH=~/.kubectx:\\$PATH\nEOF\n```\n\n#### fish\n\n```fish\nmkdir -p ~/.config/fish/completions\nln -s /opt/kubectx/completion/kubectx.fish ~/.config/fish/completions/\nln -s /opt/kubectx/completion/kubens.fish ~/.config/fish/completions/\n```\n\n \n\n> [!NOTE]\n> Tip: Show context/namespace in your shell prompt with [oh-my-posh](https://ohmyposh.dev/) or\n> simply with [kube-ps1](https://github.com/jonmosco/kube-ps1).\n\n-----\n\n### Interactive mode\n\nIf you want `kubectx` and `kubens` commands to present you an interactive menu\nwith fuzzy searching, you just need to [install\n`fzf`](https://github.com/junegunn/fzf) in your `$PATH`.\n\n\n\nCaveats:\n- If you have `fzf` installed, but want to opt out of using this feature, set the\n environment variable `KUBECTX_IGNORE_FZF=1`.\n- If you want to keep `fzf` interactive mode but need the default behavior of the\n command, you can do it by piping the output to another command (e.g. `kubectx |\n cat `).\n\n-----\n\n### Customizing colors\n\nIf you like to customize the colors indicating the current namespace or context,\nset the environment variables `KUBECTX_CURRENT_FGCOLOR` and\n`KUBECTX_CURRENT_BGCOLOR` (refer color codes\n[here](https://linux.101hacks.com/ps1-examples/prompt-color-using-tput/)):\n\n```sh\nexport KUBECTX_CURRENT_FGCOLOR=$(tput setaf 6) # blue text\nexport KUBECTX_CURRENT_BGCOLOR=$(tput setab 7) # white background\n```\n\nColors in the output can be disabled by setting the\n[`NO_COLOR`](https://no-color.org/) environment variable.\n\n-----\n\nIf you liked `kubectx`, you may like my\n[`kubectl-aliases`](https://github.com/ahmetb/kubectl-aliases) project, too. I\nrecommend pairing kubectx and kubens with [fzf](#interactive-mode) and\n[kube-ps1](https://github.com/jonmosco/kube-ps1).\n\n#### Stargazers over time\n\n[](https://starchart.cc/ahmetb/kubectx)\n \n"
