👋 It seems that this PR is adding, or editing, a GitHub Action workflow that is not configured to use our custom GitHub Action runners.

For private repositories, the only supported way of running Action workflows is via the custom runners. You can learn more about the supported use cases in our GitHub Actions documentation.

To make sure that your workflow is using these runners you need to add the shopify-ubuntu-latest label to your workflow manifest file, or shopify-core-ubuntu-latest for Core repositories:

runs-on: shopify-ubuntu-latest

If your repository is intended to become Public later, please use runs-on: shopify-ubuntu-latest for now. The custom runners should function the same as ubuntu-latest public runners, though the exact Ubuntu version may vary. Please see the section below for more information about OS selection on premium runners.

If you run into any issues with the custom runners, please reach out in help-eng-infrastructure on Discourse.

Note for OS Versions

The shopify-ubuntu-latest runners can select from two different runner pools, which contain both Ubuntu 20.04 and Ubuntu 22.04 machines. For some workflows, this can cause issues.

To use Ubuntu 20.04 only, you can specify runs-on: shopify-ubuntu-20.04.

To use Ubuntu 22.04 only, you can specify runs-on: shopify-ubuntu-latest-2.
