Experimental support for osx-arm64 (Apple M1)

[hkratz]

This is an unofficial experimental patch to make the GitHub Actions Runner work on Apple Silicon.

Try out the version based on v2.291.1:

git clone https://github.com/hkratz/gha-runner-osx-arm64.git -b macos-arm64
cd gha-runner-osx-arm64/src/
./dev.sh layout
cd ../_layout/
./config.sh --url  {repo-url} --token AA... # use your repo URL and your runner registration token

Known issues:

• Auto-updates are disabled as this is not an official runner.

Changes compared to upstream release:

• Fall back to Node 16 instead of Node 12 as earlier versions do not support ARM64.
• Add osx-arm64 runtime identifier at various places and remove implicit assumption that Darwin/osx implies X64 arch.
• Fixed failing test DetermineNodeRuntimeVersionInAlpineContainerAsync, which apparently requires x86-64 to pass.
• Disable auto-update on Macos ARM64.
• Add checksums for dotnet runtime and externals.
• Minor: Print checksum of dotnet runtime and externals in assertion failure.

Hacks could possibly be removed in the future.

Thank you, would love to try it.

What is the repo-url in this context?

And where we can lookup the runner registration token? Is there a file on our self hosted runner?

@paulz Navigate to the Actions -> Runner section of your repository settings and press the Add runner button. Use the URL and token from the $ ./config.sh --url ... command in the Configure section.

Rebased on v2.282.1.

How to disable auto-update?

After one day of using I have next message:

./run.sh

An error occurred: A package with type agent, platform osx-arm64, version 2.283.1 was not found.

I suppose this is exist, because runner try to update themselves

Yes, after changing code version detection, runner start works again

[hkratz]

I currently plan to automate rebasing+testing whenever a new version is released.

[hkratz]

Rebased on v2.284.0 and updated to use the release version of .NET 6.0.

[hkratz]

Rebased on the most current version, v2.289.1. It was a bit more involved due to new checksum code.

Should work again now, running the build of this repo with a runner on my M1 Mac worked fine.

Again had to rebase for it to pickup jobs. Sadly cannot contribute here as I would need to overwrite your changes, but the following did the job:

git remote add github git@github.com:actions/runner.git
git pull github main
git rebase -X ours main

Had to rerun config.sh tho.

Thanks for the work!

[hkratz]

Updated to v2.289.2.

[hkratz]

git remote add github git@github.com:actions/runner.git
git pull github main
git rebase -X ours main

@ahoereth Better not to rebase on main, because it frequently contains unreleased changes. Instead rebase on the most current release branch. The current release branch is releases/m289.

[hkratz]

Updated to v2.290.0.

git remote add github git@github.com:actions/runner.git
git pull github main
git rebase -X ours main

I had also to rebase with releases/m290 so the jobs can be picked up. Thx for your work.

[hkratz]

Updated to v2.290.1.

Hey @hkratz thanks for providing the ARM64 runner, I went and installed it but it seems the runner isn't picking any jobs. Based on discussion, it seems that rebasing usually helped, but even with rebasing to the latest release (releases/m291) it still isn't picking any jobs. Could you jump in and check why is this happening, or provide some steps how to reenable it in those situations? Thank you

[daiyam]

I did had to rebase my runner to releases/m291 and it's picking the jobs.

Here my commands:

git remote add github https://github.com/actions/runner.git

git pull github releases/m291
git update-ref -d MERGE_HEAD
git rebase -X ours github/releases/m291

[hkratz]

Updated to v2.291.1.

[hkratz]

No longer needed as the functionality is implemented upstream.
