Name clarity when using Helm

[ronaldpetty]

Hello. This might be a none-issue (due to inexperience), but I am a bit confused on Pod names / purpose. Just trying to confirm the flow between Pods and key purpose when installing things via the Helm charts.

This installs the "operator / controller" pod. Its job is to wait for "listeners" and report their health to GH?

helm install arc \
    --namespace "arc" \
    --create-namespace \
    oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller

This install the "listeners" pods. Their job is to poll for Jobs in GH and if they find one, tell the "operator" pod to launch an emphemeral runner.

helm upgrade "arc-testing-halo" \
    --install \
    --namespace "arc" \
    --create-namespace \
    --set githubConfigUrl="https://github.com/..." \
    --set githubConfigSecret.github_token="..." \
    --set maxRunners=2 \
    --set minRunners=1 \
    --set controllerServiceAccount.name="arc-gha-rs-controller" --set controllerServiceAccount.namespace="arc" \
    --set containerMode.type="dind" \
    oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set

When I submit a repo update, I see a new pod being created with 2 containers (assuming the runner + dind). The part that is confusing me (I think) is the the OCI helm chart name "gha-runner-scale-set". That sounds like its the runner (aka the thing the builds your thing), but in reality it is not, its just a traffic cop.

Thanks for any tips on understanding.
