actionlint self-hosted-runner labels configuration .github/actionlint.yaml custom labels

💡 Result:

To configure custom labels for self-hosted runners in actionlint, you must define them in an actionlint configuration file, typically located at.github/actionlint.yaml or.github/actionlint.yml [1][2][3]. When actionlint encounters a label in a workflow's runs-on field that it does not recognize as a standard GitHub-hosted runner, it triggers a runner-label error [4][5][6]. To resolve this for custom self-hosted runner labels, add a self-hosted-runner section to your configuration file [1][4]. Configuration Example: #.github/actionlint.yaml self-hosted-runner: labels: - my-custom-label-1 - my-custom-label-2 - linux-gpu-* Actionlint supports glob patterns for these labels, enabling flexible matching for dynamic runner labels [1][2][7]. The glob support uses the standard Go path.Match syntax [1][2][5]. If you are running actionlint via command line, you can generate a default configuration file using the -init-config flag [1][2]. If you are using actionlint through a CI integration (such as reviewdog/action-actionlint), ensure your step correctly points to your configuration file using the appropriate flags (e.g., -config-file) if it is not in the default.github/ location [8].

GitHub Actions self-hosted runner labels runs-on all labels must match custom label documentation

💡 Result:

When you specify multiple labels in the runs-on array for a GitHub Actions workflow, the matching logic is cumulative [1][2][3]. This means a self-hosted runner must possess all of the labels specified in the array to be eligible to process the job [1][4]. For example, if you define the runner as: runs-on: [self-hosted, linux, x64, gpu] The job will only be routed to a self-hosted runner that has all four of those labels assigned to it [1][2][3]. Key points regarding this behavior: - Cumulative Logic: The system uses "AND" logic for the labels listed in the array [2][5]. It does not support "OR" (either/or) logic natively through the standard runs-on label array [5]. - Matching Groups and Labels: If you combine a runner group with specific labels, the runner must belong to that group AND possess all the specified labels to be eligible for the job [1][2][4]. - Default Labels: By default, self-hosted runners are assigned labels based on their OS and architecture (e.g., self-hosted, linux, x64) [1]. When using multiple labels, these default labels are treated the same as custom labels, meaning the runner must include them if you list them in your runs-on requirement [1]. - Queuing: If no runner is found that matches all specified labels, the job will remain queued until a matching runner becomes available or the job times out after 24 hours [6].

Add rpi to the actionlint runner-label configuration.

The three jobs use rpi, but the repository has no .github/actionlint.yaml. Add rpi under self-hosted-runner.labels. Also ensure an online runner has self-hosted, linux, ARM64, and rpi; otherwise GitHub can leave these jobs queued.

Declare and validate the self-hosted runner toolchain.

The gate invokes gh, jq, and grep -P, but it does not install or check them. If the [self-hosted, linux, ARM64, rpi] image lacks one command, the job exits before posting the Bot Blocking Gate check-run. Add a preflight check or document the required image.
