Hey, thanks for reporting! What OS and brew version are you using? I've just executed a quick test with docker and it worked as expected:

❯ docker run -ti --user 1000 linuxbrew/brew:3.2.5 brew tap little-angry-clouds/my-brews

Not really sure how to proceed, from my computer it works and I've tried from a clean docker Image. The only difference I see is that you use Mac. @romancin could you please try to reproduce this?

[romancin]

Of course! I will try to help. @davebarr viewing the output of brew config, we can see you are using Apple Silicon. @alexppg The problem is that particle.rb formula only contains URL for Intel on macOS:

on_macos do
    if Hardware::CPU.intel?
      url "https://github.com/little-angry-clouds/particle/releases/download/v0.0.8/particle_0.0.8_darwin_amd64.tar.gz"
      sha256 "3a930819203cde6f917e1b6cf88f38eb75c634210d931e862d077c0d8dcb466a"
    end
  end

To fix this, we also need a formula for arm also on macOS on that file.

Said that, @davebarr I don’t think installing helmenv, kbenv or ocenv on Apple Silicon brew is a good idea if you are going to work with old kubernetes versions.

This is because these tools will search for arm64 darwin architecture when trying to download kubectl from the official URLs, and these tools were not compiled for darwin arm64 until 1.21 version, as you can see on this browsable storage: https://gcsweb.k8s.io/gcs/kubernetes-release/release/?marker=release%2fv1.20.4-rc.0%2f

In case of Helm, darwin arm64 is only available since 3.6.0.

In my case, I also have Apple Silicon, but I have 2 different brew versions installed: One using Rosetta 2 installed on /usr/local (this is the one I use to install helmenv, kbenv and ocenv), and the other one like you, over /opt for native brew for Apple Silicon. I have in my zshrc a function called ibrew that calls Rosetta 2 enabled brew to make things easier.

If you think this can be a good idea for you too, I can help you to achieve the same configuration.

[davebarr]

Ah good point about the old kubernetes versions. That's a good idea about having another brew install, I will check that out. In the meantime I was able to get it installed under rosetta by just doing

arch -x86_64 brew tap little-angry-clouds/my-brews

and the install went successfully. (this was after installing rosetta, of course)

Thanks for the help!

[alexppg]

Thanks to both of you! Should I add some kind of documentation for other people that have corner issues like this, or is this really not usual?

[romancin]

@alexppg maybe we can do two things:

• Add formula for arm support under on_macos
• Add a note in the README.md telling that the tool supports native Apple Silicon above kubectl 1.21 and Helm 3.6.0.

[alexppg]

Nice, thanks! I didn't understand anything about Silica and rosetta, it's usual to have multiple brew installations? Should I add something in the readme?

[alexppg]

I've regenerated the latest version to add more macos archs. Could you download one manually and say if it works for you? In the next real release, it will be added properly to the formula. https://github.com/little-angry-clouds/particle/releases/tag/v0.0.8

[davebarr]

it works now, thanks!

[alexppg]

Hey @romancin I created a fake release on particle just to add the recipes in here. Could you please confirm that it works as expected know?

[gtfortytwo]

Do you ever intend to release the support for Apple silicon? I'm migrating from Win/WSL and already really miss kbenv in particular. kubectl is pretty finicky about version skew, but they've been building ARM-native binaries for long enough that it covers my use cases. I've not been able to figure out how to translate the comments here into something usable as-is, but would be happy to help test a release with further direction. Thanks!

[alexppg]

I do, I'll update it here https://github.com/little-angry-clouds/homebrew-my-brews/issues/27 and close this issue since it seems it should work.
