How to install old versions of Homebrew formulas and switch between them
Raw
install-old-homebrew-formulas.md

This example uses istioctl as the formula, but this may come in handy for kubernetes-cli, kubernetes-helm, etc.

  1. Find the formula for your executable, e.g. istioctl, and click on the link to GitHub: 
    brew info istioctl | grep Formula
  2. Click "Blame" button ("History" will be too large to display).
  3. Hopefully, you can find an earlier versioned commit message... click on it.
  4. Click ... in upper-right of next page, select "View File" from drop-down.
  5. Right-click "Raw" button, and Copy URL Address.
  6. Paste URL into install command, which will look something like: 
    brew install https://github.com/Homebrew/homebrew-core/raw/af5f8075d6c64e555812ce818e1d52fe0613b030/Formula/istioctl.rb
  7. If all goes well, you should be able to switch between versions. Use this command fragment to find available versions: 
    brew switch istioctl
  8. Use complete command to relink and switch to using that version: 
    brew switch istioctl 1.0.5

Found this alternative which is more compatible with my brew version(recent):
