Configure action runner in eks+calico environment

Last week I setup our staging kubernetes environment, however the once worked version of runnerset yaml configuration didn’t work. I tried different combination of controller and summerwind/actions-runner-dind image, fully customized template portion with RUNNER_xxx arguments. I still got "Http response code: NotFound from 'POST https://api.github.com/actions/runner-registration'" for every combination of those combinations in the logs of runner pods. I thought RunnerDeployment is stateless and less complex than RunnerSet. I gave it a try. This time, I got a differnet error message "failed calling webhook "mutate.runner.actions.summerwind.dev"" when I created a RunnerDeployment.

In Nov 2021, I encountered the same kind of errors when I installed cert-manager in same configuration of environments EKS+Calico(networking and policy). You can find at here Configure cert-manager and godaddy webhook on eks with calico-vxlan. I knew how to handle this error.

I downloaded the manifest yaml from actions-runner-controller.yaml and created one kustomization.yaml and json patch file to add hostNetwork. Here is my configuration.

// controller-manager-patch.json
[
    {
        "op": "add",
        "path": "/spec/template/spec/hostNetwork",
        "value": true
    }
]

# kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- actions-runner-controller.yaml
- controller-manager.yaml

patches:
- path: controller-manager-patch.json
  target:
    group: apps
    version: v1
    kind: Deployment
    name: controller-manager

actions-runner-controller is a great project. I used it in three projects. I intended to use it in my future projects as well and I may encounter the same issue in the future. I created an issue for me or others to track down the issue.
