 # Helm values for ARC runner scale set
 # Chart: oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set
 # Namespace: arc-system
+#
+# Custom DinD template with resource requests to spread pods across nodes.
+# containerMode is NOT set — we provide the full template ourselves.
+# Based on the chart's default DinD template for Kubernetes >= v1.29 (sidecar containers).
 
-# GitHub repository to register the runner against
 githubConfigUrl: "https://github.com/celesrenata/stonks-oracle"

-# Runner label used in workflow runs-on
 runnerScaleSetName: "self-hosted-gremlin"
 
-# Authentication — GitHub PAT injected at install time via --set
-# runmefirst.sh reads /run/secrets/github_token and passes it here
 githubConfigSecret:

-# Docker-in-Docker mode — runner has a full Docker daemon, works like GitHub-hosted runners
-# NOTE: Do NOT override template.spec when using containerMode — the chart auto-injects
-# the correct DinD sidecar, volume mounts, DOCKER_HOST env, and startup probes.
