Github(Enterprise) action(runs on docker linux) with SonarQube scanner action fail

I have a question.
I’m currently using Github Enterprise.
I am trying to link Github action and sonarqube.

Github Enterpise installed linux OS on Docker because the action runner had to be self-hosted, not github, so the runner works.

But I am getting the following error:

Build container for action use: ‘/actions-runner/actions-runner/_work/_actions/sonarsource/sonarqube-scan-action/master/Dockerfile’.
Error: File not found: ‘docker’

Does the sonarqube github action not work in linux OS on top of Docker?
Or is there something special to set up or do?

Thank you for your reply.

thank you. :slight_smile:
