Add kubernetes-related tools

[AlanGreene]

• kubetail
• kubectx / kubens
  • completion
  • ln -s /usr/local/Cellar/kubectx/0.6.3/etc/bash_completion.d/kubectx ~/.bash_completion/kubectx
  • ln -s /usr/local/Cellar/kubectx/0.6.3/etc/bash_completion.d/kubens ~/.bash_completion/kubens
• kube-ps1 ?

• bash prompt

  • 
    # kubernetes context:namespace

  KUBE_PS1_ENABLED=off

  kube_prompt() { if [[ "${KUBE_PS1_ENABLED}" = "on" ]]; then echo "${bold}${orange}kubectl config current-context${white}:${cyan}kubectl config view -o'jsonpath={..namespace}'${reset}" fi; }

  kubeon() { KUBE_PS1_ENABLED=on }

  kubeoff() { KUBE_PS1_ENABLED=off }

• aliases (clean this up, combine alias + completion)

  alias k="kubectl"
  alias ka="kubectl apply -f"
  alias kc="kubectx"
  alias kg="kubectl get"
  alias kl="kubectl logs"
  alias klf="kubectl logs -f"
  alias kn="kubens"
  alias krm="kubectl delete"
  alias kx="kubectl exec -i -t"
  
  complete -F __start_kubectl k
  #complete -F _kube_contexts kc
  #complete -F _kube_namespaces kn
  complete -F _complete_alias kc
  complete -F _complete_alias kg
  complete -F _complete_alias kl
  complete -F _complete_alias klf
  complete -F _complete_alias kn
  complete -F _complete_alias krm
  complete -F _complete_alias kx

  • completion https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion + https://github.com/AlanGreene/complete-alias
  • update /etc/shells to add /usr/local/bin/bash
  • chsh -s /usr/local/bin/bash
  • echo $BASH_VERSION to verify
  • now need to rename ~/.bash_completion/ to ~/.bash_completion.d/ as .bash_completion is expected to be a file (also update reference in ~/.bash_profile)

• https://github.com/mumoshu/config-registry might just stick to existing approach with KUBECONFIG environment variable and custom aliases (e.g. idsprod)

• https://github.com/corneliusweig/rakkess looks useful, maybe cook up something similar but simpler / more tailored to my own needs what are the benefits over kubectl auth can-i --list or similar?
