Installing older version of kubernetes-helm with brew (Downgrading helm)

There might be many reason you may need to downgrade the helm installation version or install a specific version.

Some of the examples are :

1. Output of helm version: client - v2.x.x, server v2.y.y.
   Output of kubectl version: client :- v1.x.x, server:- v1.y.y
2. Other reason could be using service like jenkins-x which apparently doesn’t support helm3.

So, follow these simple steps to get the specific version of helm installed.

• Search on Github for the correct kubernetes-helm.rb file for the version I wanted (2.9.x in my case): https://github.com/Homebrew/homebrew-core/search?q=kubernetes-helm&type=Commits
• Click the commit hash button (78d6425)
• Open the kubernetes-helm.rb file and Click the “View” button
• Click the “Raw” button
• And copy the url: https://raw.githubusercontent.com/Homebrew/homebrew-core/78d64252f30a12b6f4b3ce29686ab5e262eea812/Formula/kubernetes-helm.rb

Then run the following command once you have the url for the correct kubernetes-helm.rb file

$ brew unlink kubernetes-helm
$ brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/78d64252f30a12b6f4b3ce29686ab5e262eea812/Formula/kubernetes-helm.rb
$ brew switch kubernetes-helm 2.9.1

Hope this helps someone.

Btw going off-topic for all quarantined office people,

Recently, I switched from iOS to Android. And I was missing Apple’s Continuity feature. Where I could easily make or receive phone calls on Mac, get access OTPs, messages quickly on my Mac.

I noticed I was ending up landing social media or hacker-news :D spending hours every-time I picked up my phone for a call(there’re a lot in this work from home situation).

And then after spending a day, going through a lot of spam! I noticed this app on App Store called “Connecton”. I’m surprised why was it hard to find it.

Putting out loud, so that I can save someone’s time who needs this.
