How to change docker:dind image or customize dind container with commands included using helm charts?

[ram1ex]

Installing gha-runner-scale-set using this way:

helm upgrade --install "${INSTALLATION_NAME}" --namespace "${NAMESPACE_RUNNER}" --create-namespace --set githubConfigUrl="${GITHUB_CONFIG_URL}" --set githubConfigSecret.github_token="${GH_PAT}" --values values.yaml oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set

in values.yaml i'd specify my custom image with specific docker setup ( mostly needs to customize daemon.json and private registry) like this:

containerMode:
  type: "dind"
template:
  spec:
    containers:
     - name: dind
      image: my_own_image_from_docker_hub

Also it's not possible to put command in values like this:

containerMode:
  type: "dind"
template:
  spec:
    containers:
    - name: dind
      image: docker:dind
      command: [ "/bin/sh", "-c", "mkdir -p /etc/docker ; touch /etc/docker/daemon.json"]

(btw it works for 'runner' container)

It was resolved. containerMode should be excluded from values, then it's possible to configure your own image using this template https://github.com/actions/actions-runner-controller/blob/master/charts/gha-runner-scale-set/values.yaml.
But it looks different when we put containerMode and change runner container config...
Closing the ticket.
