Choose architecture for a GitHub job runner

I was reading this documentation on how to select the runner for a job in a GitHub workflow.

However, is there a way to select the architecture as well, such as in a strategy matrix? My workflow builds my project and then runs tests. I'd like it to run on linux/i386 as well as linux/amd64.

Solution

  • As of now, all the GitHub-hosted runners only support x86_64 architecture.

    See Supported runners and hardware resources.

    Even for self-hosted runners, only these architectures are supported:

    • x64 - Linux, macOS, Windows.
    • ARM64 - Linux, macOS, Windows (currently in beta).
    • ARM32 - Linux.

    x86 binaries should run just fine on x64 runners. However, you may use Docker images for your tests.
