To Reproduce

1. Start with an EKS auto cluster
2. Follow quick start instructions https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/quickstart-for-actions-runner-controller
3. Follow the kubernetes runner instructions https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/deploying-runner-scale-sets-with-actions-runner-controller#using-docker-in-docker-or-kubernetes-mode-for-containers
4. Follow this troubleshooting step https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/troubleshooting-actions-runner-controller-errors#error-access-to-the-path-homerunner_work_tool-is-denied
5. Launch any github action that runs on a container

Describe the bug

The github action fails on the step "Initializing containers" with the message:

Run '/home/runner/k8s/index.js'
  shell: /home/runner/externals/node20/bin/node {0}
Error: Error: Missing file at path: /home/runner/_work/_temp/_runner_hook_responses/{...}.json
Error: Process completed with exit code 1.
Error: Executing the custom container implementation failed. Please contact your self hosted runner administrator.

The workflow runner (the -workflow pod) starts and instantly dies, printing no logs.

I've also tried fsGroup: 1001 and it didn't work either. Without fsGroup I get the /home/runner/_work/_tool access error.

Describe the expected behavior

The action should progress past "Initializing containers". The workflow pod presumably should print something.

Hey @jennifgcrl,

If you don't use the fs group, does it work? Please submit the runner log. This issue doesn't seem to be related to ARC, but let's keep it open here, and maybe we can help troubleshoot the issue.

[jennifgcrl]

Without the fs group it shows "Error: Access to the path /home/runner/_work/_tool is denied"

Here's the runner log: https://gist.github.com/jennifgcrl/e6b770387e248e7bbe59b3b9fa16fdda

The relevant lines seem to be:

arc-runner-set-wtqrv-runner-l7w65 runner [WORKER 2025-04-03 13:13:31Z ERR  StepsRunner]  ---> System.UnauthorizedAccessException: Access to the path '/home/runner/_work/_temp/_runner_hook_responses' is denied.

What image are you using for the runner?

[jennifgcrl]

Runner is ghcr.io/actions/actions-runner:latest

Workflow is:

name: Hello containers
run-name: Hello, containers!
on:
  push:
    branches:
      - master
jobs:
  build-builder:
    runs-on: arc-runner-set
    container:
      image: ubuntu:latest
    steps:
      - run: echo "Hello, world!"

I have the same issue. I do not have anything to add, as my setup is pretty much identical to @jennifgcrl.

I wonder @nikola-jokic, how can this not be an ARC issue? It occurs when running the simplest workflow and with a simple ARC installation.

@jennifgcrl: have you been able to fix this issue?

[jennifgcrl]

No, I worked around it by not using the k8s containermode. I rewrote my actions to run in the default arc image and launch the actual job in a separate pod.
