I created a workflow on a Github Enterprise server. I want to build & push the container with the docker/build-push-action and before push I want to run some tests in the container.

My Workflow file looks like this:

name: Docker Image Build & Push

on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]
  workflow_dispatch:

permissions:
  contents: read
  packages: write

jobs:
  build:
    name: Build & Push Container
    runs-on: [self-hosted, linux, docker]
    steps:
      - name: Checkout
        uses: actions/checkout@v3

      - name: Docker Meta
        id: meta
        uses: docker/metadata-action@v5
        with:
          images: |
           registry.private/user/image
          tags: |
            type=schedule
            type=ref,event=branch
            type=ref,event=pr
            type=semver,pattern={{version}}

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3
        with:
          driver: docker-container

      - name: Login to Registry
        uses: docker/login-action@v3
        with:
          username: ${{ github.actor }}
          password: ${{ secrets.GITHUB_TOKEN }}
          registry: registry.private

      - name: Docker Build
        uses: docker/build-push-action@v5
        with:
          push: false
          context: .devcontainer
          tags: ${{ steps.meta.outputs.tags }}
          labels: ${{ steps.meta.outputs.labels }}

      - name: Run some commands in the container
        uses: addnab/docker-run-action@v3
        with:
          image: registry.private/user/image
          run: whoami && pwd
      
      # Put here the step for the push

Everything works fine except the execution of the addnab/docker-run-action@v3 action. I got the following error message:

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

I found following issue on Github, but there was also no working solution.
