Checks

• [x] This isn't a question or user support case (For Q&A and community support, go to Discussions. It might also be a good idea to contract with any of contributors and maintainers if your business is so critical and therefore you need priority support
• [x] I've read releasenotes before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes
• [X] My actions-runner-controller version (v0.x.y) does support the feature
• [X] I've already upgraded ARC (including the CRDs, see charts/actions-runner-controller/docs/UPGRADING.md for details) to the latest and it didn't fix the issue
• [X] I've migrated to the workflow job webhook event (if you using webhook driven scaling)

2.Deploy action runner controller on AKS with kubernetes values.yaml

Hello search engine user,

I also ran into this problem today. My setup is a Kubernetes cluster with DinD. We use Docker containers in some Github jobs. So that the external tools are also available in Dind, I have created an initContainer which copies externals directory into an emptyDir volume.

initContainers:
- name: init-runner
  image: ghcr.io/actions/actions-runner:latest
  imagePullPolicy: IfNotPresent
  command: ["sh", "-c", "cp -ar /home/runner/externals/* /externals/"]
  volumeMounts:
    - name: externals
      mountPath: /externals
containers:
- name: runner
  image: ghcr.io/actions/actions-runner:latest
...snip...
  volumeMounts:
    - name: work
      mountPath: /home/runner/_work
    - name: externals
      mountPath: /home/runner/externals
...snip...
- name: dind
  imagePullPolicy: IfNotPresent
  image: docker:dind
...snip...
  volumeMounts:
    - name: work
      mountPath: /home/runner/_work
    - name: externals
      mountPath: /home/runner/externals

hope it helps
