Common ZSHRC Extensions

When using oh-my-zsh, you can add some extensions and custom code to your .zshrc file to improve your workflow. Below are some common extensions that can be added to your .zshrc file.

• Useful zsh plugins

  • Add these to your .zshrc file: plugins=(git kubectl kube-ps1)

• kubectx

  • A utility to switch between Kubernetes contexts and namespaces easily. It provides a command-line interface to manage multiple Kubernetes clusters and namespaces efficiently.

  Run kubens namespace-name to switch to the desired Kubernetes namespace.

  

• alias for kube context switching

  • Add the following alias to your .zshrc file to switch between Kubernetes contexts easily:

  alias kx="/opt/homebrew/bin/kubectx"

  Run kx aks-cluster-name to switch to the desired Kubernetes context.

  

• kube-ps1

  • A Zsh prompt extension that displays the current Kubernetes context and namespace in your terminal prompt. It helps you keep track of which cluster and namespace you are working with.

  

• Master/main push sanity checks

  • Add the following code to your .zshrc file to prevent accidental pushes to the master or main branches. This code will check if you are on the master or main branch and prompt you for confirmation before allowing the push.

  # Sanity Checks
  preexec () { 
    if [[ ${1} =~ "gpush" || ${1} =~ "git push" ]];then 
      branch=$(git branch --show-current)
      # Check if branch is main or master and stop push going straight through
      if [[ ${branch} == "master" || ${branch} == "main" ]];then
        read -q "execStatus?-----  To master? Really? [y/n]  ----- "
        if [[ ${execStatus} == "y" ]];then
          printf "\nExecuting...\n"
        else
          printf "\nCancelled $1... Refreshing shell.\n"
          exec zsh
        fi
      fi
    fi
  }

• Automatically switch to main/master when you get the branch wrong
  • Add the following code to your .zshrc file to automatically switch to the main or master branch if you try to checkout a non-existent branch.

  git() {
    if [[ "$1" == "checkout" && "$#" -eq 2 ]]; then
      case "$2" in
        master)
          command git checkout master || command git checkout main
          ;;
        main)
          command git checkout main || command git checkout master
          ;;
        *)
          command git "$@"
          ;;
      esac
    else
      command git "$@"
    fi
  }

• Use functions to make switching azure account easier
  • Add the following aliases to your .zshrc file to switch between Azure accounts easily:

  # Login automatically
  function az_login_hmcts {
      export AZURE_CONFIG_DIR=~/.azure
      az login
  }

  # Prompt for device code so it doesn't use your default account
  function az_login_crime_nonlive {
      export AZURE_CONFIG_DIR=~/.azure-crime-nonlive
      az login --use-device-code
  }

  # Prompt for device code so it doesn't use your default account
  function az_login_crime_live {
      export AZURE_CONFIG_DIR=~/.azure-crime-live
      az login --use-device-code
  }
