Run azure/CLI@v2 failing with Error: docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

• github actions self-hosted runner , hosted on azure container app job as mentioned in below tutorial -
  https://learn.microsoft.com/en-us/azure/container-apps/tutorial-ci-cd-runners-jobs?tabs=bash&pivots=container-apps-jobs-self-hosted-ci-cd-github-actions
• Self Hosted runner is working for other job steps - checkout@v3 , azure/login@v2 , terraform setup etc. But it is failing for azure/CLI@v1 and v2

Any log messages given by the failure

Starting script execution via docker image mcr.microsoft.com/azure-cli:latest
Error: Error: docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.

cleaning up container...
Warning: Error: The process '/usr/bin/docker' failed with exit code 1
Warning: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

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

Expected/desired behavior

azurecli should work

OS and Version?

Architecture": "amd64",
"Os": "linux",
"OsVersion": "20.10.25+azure-1",

Versions

Architecture": "amd64",
"Os": "linux",
"OsVersion": "20.10.25+azure-1",

Mention any other details that might be useful

container is not able to start docker daemon for host .. docker client commands - docker run etc. are available.
Self Hosted runner is working for other job steps - checkout@v3 , azure/login@v2 , terraform setup etc. But it is failing for azure/CLI@v1 and v2
Thanks! We'll be in touch soon.

You should install azure cli on the runner ahead of time and use it directly in your action

Add to the dockerfile

# Download and install Azure CLI using Micosoft's script
RUN curl -sL https://aka.ms/InstallAzureCLIDeb | bash

I think you won't be able to run docker inside docker in container app jobs

[PhucTo-Veeam]

@rbourdon, does that mean I can't run a Docker build job with the GitHub runner container app setup?

[InsulaVentus]

@PhucTo-Veeam that is correct:

"Container apps and jobs don't support running Docker in containers. Any steps in your workflows that use Docker commands fail when run on a self-hosted runner or agent in a Container Apps job."
