how can i switch the color of my terminal when i switch kubernetes context and kube-ps1 detect it?
Here's a step-by-step guide on how to achieve this:
Install kube-ps1: If you haven't already installed kube-ps1, you can do so from its GitHub repository: https://github.com/jonmosco/kube-ps1
Configure your shell to use kube-ps1: Add the following lines to your shell configuration file (.bashrc, .zshrc, etc.) to initialize kube-ps1:
source "/path/to/kube-ps1.sh" PROMPT='$(kube_ps1)'$PROMPT Replace "/path/to/kube-ps1.sh" with the actual path where kube-ps1 is located.
Modify kube-ps1 prompt: Customize the kube-ps1 prompt to change colors based on the current Kubernetes context. You can do this by modifying the kube-ps1 function in your .bashrc or .zshrc file. Here's an example of how you can do this for bash:
function kube_ps1() {
local ctx=$(kubectl config current-context)
local red='[\033[0;31m]' local green='[\033[0;32m]' local blue='[\033[0;34m]' local reset='[\033[0m]'
case "$ctx" in production-context) # Set color to red for production color=$red ;; staging-context) # Set color to blue for staging color=$blue ;; *) # Set color to green for other contexts color=$green ;; esac
echo -n "${color}(k8s: ${ctx})${reset} " }
PS1='$(kube_ps1)'$PS1 For zsh, use %F{color} for setting colors and %f for resetting them.
Reload your shell configuration: After making changes to your shell configuration file, apply them by either restarting your terminal or sourcing the configuration file:
source ~/.bashrc # or source ~/.zshrc if you're using zsh
Switch Kubernetes contexts: Now, when you switch Kubernetes contexts using kubectl, your terminal prompt should change colors based on the context you are currently using.
Remember that you may need to adjust the script above to fit the specific syntax of your shell, and also replace the context names (production-context, staging-context, etc.) with the actual context names you use.
