gitlab pipeline Preparation failed: Cannot connect to the Docker daemon at unix:///var/run/docker.sock

when i start the pipeline in nest-of-gold and awesome-app:

i try many methods but fail to solve it.Can you tell me how to solve it？

I find why it happens.My computer is mac m1 arm64,usually i use env DOCKER_DEFAULT_PLATFORM=linux/amd64 to be compatible with other service's docker image which don't support arm64.So i build cicd-goat in amd64.Usually it's fine when other images,but cicd-goat can't.So I change the env DOCKER_DEFAULT_PLATFORM=linux/arm64 and change the docker-compose.yaml:

version: "3.8"

networks:
  goat:
    driver: bridge

then everything is fine.

Thank you for the solution, looks like an environment specific case so I'll close the issue
