ARM64 runners

[Serhii Kaidalov (NMI)]

Is there a way to run arm64 runner to build arm docker images? 

For example introduce some additional label or nodeSelector, so karpenter can launch a proper instance for that runner.

@Serhii Kaidalov (NMI) hi. If you speaking about runners-autoscaler tool, then this feature is not supported. There was a plan to implement this, but i'm not sure when this feature will become available.

Regards, Igor.

Got it. Would be great to see that in the future.

@Igor Stoyanov what about runners-autoscaler image itself? Could you build it for arm64 as well? 

[Igor Stoyanov]

@Serhii Kaidalov (NMI) actually i provided response for the runners-autoscaler image. ARM64 infra is not supported in a current state of development for this image.
For the image that is used to create runners 

docker-public.packages.atlassian.com/sox/atlassian/bitbucket-pipelines-runner:1 , as i know, support of arm64 infra is in the BETA state of development.

Regards, Igor.

@Igor Stoyanov got it, thanks.

Hi @Serhii Kaidalov (NMI) - for reference, information on the ARM support with runners is available here: https://bitbucket.org/blog/announcing-support-for-linux-arm-runners-in-bitbucket-pipelines

The team has not 100% confirmed the functionality of ARM runners + the Autoscaler yet, I'll update you here once we've done our own validation testing.

 Awesome, it there a guide how to build multi-arch image? 

[Edmund Munday]

@[deleted] - so at this stage the Auto-scaler most likely isn't going to play nicely with ARM runners, due to the fact that the auto-scaler itself is built on X86 and will be expecting that architecture in the environment that it runs.

Multi-arch images is something that we don't have official support for at the moment. That is being tracked here: https://jira.atlassian.com/browse/BCLOUD-15317
