What settings to use bitbucket runner autoscaler for arm64?

[Ethan Stein]

I've been struggling to figure out what deployment.yaml settings I need to use so I can leverage arm64 for the bitbucket runner autoscaler. Hoping someone can help?

The kustomize files here appear to only be for amd64

Yeah, so due to the way the runner autoscaler works with automatically adding the 'linux', 'self.hosted', and 'autoscale.created' labels made it impossible to have more than one. So I had to patch my own. That also allowed me to create an ARM64 version. Now it's working. Sad they had to code it like that. Makes no sense really.

@Ethan Stein care to share your version of the autoscaler that you made for ARM64 architectures?

You can make it work for ARM64 via Kustomize.
