Kubie

kubie is an alternative to kubectx, kubens and the k on prompt modification script. It offers context switching, namespace switching and prompt modification in a way that makes each shell independent from others. It also has support for split configuration files, meaning it can load Kubernetes contexts from multiple files. You can configure the paths where kubie will look for contexts, see the settings section.

Kubie also has other nice features such as kubie exec which allows you to execute commands in a context and a namespace without having to spawn a shell and kubie lint which scans your k8s config files for issues and informs you of what they are.

Thanks to @ahermant for the lovely logo!

Installation

Binary

You can download a binary for Linux or OS X on the GitHub releases page. You can use curl or wget to download it. Don't forget to chmod +x the file!

Cargo

You can build kubie from source using cargo and crates.io. If you do not have a Rust compiler installed, go to rustup.rs to get one. Then you can run cargo install kubie and kubie will be downloaded from crates.io and then built.

Homebrew

You can install kubie from Homebrew by running brew install kubie.

MacPorts

You can also install kubie from MacPorts by running sudo port install kubie.

Nix

There is a kubie Nix package maintained by @illiusdope that you can install.

Arch Linux

kubie is available in the community repository and it can be installed by running pacman -S kubie.

Autocompletion

Bash

If you want autocompletion for kubie ctx, kubie ns and kubie exec, please install this script:

sudo cp ./completion/kubie.bash /etc/bash_completion.d/kubie

Then spawn new shell or source copied file:

. /etc/bash_completion.d/kubie

Fish

Install the completions script kubie.fish by copying it, eg.:

cp completion/kubie.fish ~/.config/fish/completions/

Then reopen fish or source the file.

Usage

Note that if you have fzf installed, the experience will be greatly improved. Selectable menus will be available when using kubie ctx and kubie ns.

kubie ctx show the list of available contexts (if fzf is installed, display a selectable menu of contexts)
kubie ctx <context> switch the current shell to the given context (spawns a shell if not a kubie shell)
kubie ctx - switch back to the previous context
kubie ctx <context> -r spawn a recursive shell in the given context
kubie ctx <context> -n <namespace> spawn a shell in the given context and namespace
kubie ns show the list of available namespaces (if fzf is installed, display a selectable menu of namespaces)
kubie ns <namespace> switch the current shell to the given namespace
kubie ns - switch back to the previous namespace
kubie ns <namespace> -r spawn a recursive shell in the given namespace
kubie exec <context> <namespace> <cmd> <args>... execute a command in the given context and namespace
kubie exec <wildcard> <namespace> <cmd> <args>... execute a command in all the contexts matched by the wildcard and in the given namespace
kubie exec <wildcard> <namespace> -e <cmd> <args>... execute a command in all the contexts matched by the wildcard and in the given namespace but fail early if any of the commands executed return a non-zero exit code
kubie edit if fzf is installed, display a selectable menu of contexts to edit
kubie edit <context> edit the file that contains this context
kubie edit-config edit kubie's own config file
kubie lint lint k8s config files for issues
kubie info ctx print name of current context
kubie info ns print name of current namespace
kubie info depth print depth of recursive contexts
kubie update will check the latest kubie version and update your local installation if needed

Settings

You can customize kubie's behavior with the ~/.kube/kubie.yaml file. The settings available and their defaults are available below.

# Force kubie to use a particular shell, if unset detect shell currently in use.
# Possible values: bash, dash, fish, xonsh, zsh
# Default: unset
shell: bash

# Configure where to look for kubernetes config files.
configs:

    # Include these globs.
    # Default: values listed below.
    include:
        - ~/.kube/config
        - ~/.kube/*.yml
        - ~/.kube/*.yaml
        - ~/.kube/configs/*.yml
        - ~/.kube/configs/*.yaml
        - ~/.kube/kubie/*.yml
        - ~/.kube/kubie/*.yaml

    # Exclude these globs.
    # Default: values listed below.
    # Note: kubie's own config file is always excluded.
    exclude:
        - ~/.kube/kubie.yaml

# Prompt settings.
prompt:
    # Disable kubie's custom prompt inside of a kubie shell. This is useful
    # when you already have a prompt displaying kubernetes information.
    # Default: false
    disable: true

    # When using recursive contexts, show depth when larger than 1.
    # Default: true
    show_depth: true

    # When using zsh, show context and namespace on the right-hand side using RPS1.
    # Default: false
    zsh_use_rps1: false

    # When using fish, show context and namespace on the right-hand side.
    # Default: false
    fish_use_rprompt: false

    # When using xonsh, show context and namespace on the right-hand side.
    # Default: false
    xonsh_use_right_prompt: false

# Behavior
behavior:
    # Make sure the namespace exists with `kubectl get namespaces` when switching
    # namespaces. If you do not have the right to list namespaces, disable this.
    # Default: true
    validate_namespaces: true

    # Enable or disable the printing of the 'CONTEXT => ...' headers when running
    # `kubie exec`.
    # Valid values:
    #   auto:   Prints context headers only if stdout is a TTY. Piping/redirecting
    #           kubie output will auto-disable context headers.
    #   always: Always prints context headers, even if stdout is not a TTY.
    #   never:  Never prints context headers.
    # Default: auto
    print_context_in_exec: auto
