Kubie

<img src="./assets/logo.svg" align="right"/>

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 extra 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

Selectable menus will be available when using kubie ctx and kubie ns.

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

# For the commands `kubie edit/edit-config`
# Possible values: Any installed text editor
# Default: unset
default_editor: vim

# 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: false

    # 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:
    # Namespace validation and switching behavior.  Set to "false" if you do not have
    # the right to list namespaces.
    # Valid values:
    #   true:    Make sure the namespace exists with `kubectl get namespaces`.
    #   false:   Switch namespaces without validation.
    #   partial: Check for partial matches when running `kubie ns <namespace>`
    #            and no exact match is found:
    #              - if exactly one namespace partially matches, switch to that namespace
    #              - if multiple namespaces partially match, select from those
    # 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

# Optional start and stop hooks
hooks:
    # A command hook to run when a CTX is started.  
    # This example re-labels your terminal window
    # Default: none
    start_ctx: >
        echo -en "\033]1; `kubie info ctx`|`kubie info ns` \007"

    # A command hook to run when a CTX is stopped
    # This example sets the terminal back to the shell name
    # Default: none
    stop_ctx: >
        echo -en "\033]1; $SHELL \007"

For distro maintainers

Since 0.19.0, the self update functionality is behind a feature. You can use cargo build --release --no-default-features to produce a binary without the self update functionality. It's probably better if people rely on the distro's package manager for updates over this functionality. The binary produced is also quite smaller since it has fewer dependencies.
