How do I install ansible version 2.7 via brew in order to use kubespray on macos?

Question

I'm trying to run kubespray on macos. However, brew only has ansible at version 2.8 and kubespray requires 2.7. How can I install ansible 2.7 via brew?

Answer 1

Brew doesn't have a formula for ansible prior to 2.8; however, you can install the previous 2.7.10 method by using the git commit from brew on github to reference that version and switch.

brew install ansible 
brew unlink ansible
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/0b01263b6e11cb11d583e1e6cf870386f092cf43/Formula/ansible.rb
brew switch ansible 2.7.10
ansible --version
