In most projects with Kubernetes systems, we see a lot of different custom setups how people deal with multiple Kubernetes environments.
The most convenient way I encountered so far is direnv.
🥇
direnv- unclutter your.profile
TL&DR
Install direnv - tune your .zshrc like this:
eval "$(direnv hook zsh)"
eval "$(starship init zsh)"
Then activate on a per-directory basis via .envrc:
$ cd environment/dev
direnv: error … .envrc is blocked. Run `direnv allow` to approve its content
$ direnv allow
…
direnv: export +KUBECONFIG
Sample Setup Session for OSX
The following is more or less the log of an installation session for a developer working with several Kubernetes environments/projects. We assume Homebrew to already present on the system.
Depending on your distribution, please follow the installation documentation.
$ brew install direnv
…
==> Pouring direnv--2.31.0.monterey.bottle.tar.gz
🍺 /usr/local/Cellar/direnv/2.31.0: 11 files, 9MB
(bonus) Starship - cross-shell prompt
starship - The minimal, blazing-fast, and infinitely customizable prompt for any shell!
In combination with direnv, you’ll never get lost in your Kubernetes universe again :-)
$ brew install starship
…
🍺 /usr/local/Cellar/starship/1.6.3: 11 files, 6.2MB
Tune the configuration in .config/starship.toml…
[kubernetes]
format = 'on [⛵ ($user on )($cluster in )$context \($namespace\)](green) '
disabled = false
…and you’ll always know your current Kubernetes context.
(bonus) Nerd Fonts
brew tap homebrew/cask-fonts
brew install font-fira-code
brew install font-Fira-Code-nerd-font
brew install font-hack-nerd-font
Then configure the font-family Hack Nerd Font in your favorite terminals and tools…
Kudos to Quack~ for Mac install Nerd Font (Fire code)
🚀 Happy K8s hacking!
