Hi,

Followed the example configuration and got he error above, I did not dig deeper, wanted to drop a question while I investigate. Please let me know if I am missing any configuration, Previous I was using amidos/dcind. Trying to test it out, as I have been have some stability issues with that image.

Thank youl

Hi Karlkfi,
I'm having issues using your image. Here is the error I'm receiving when running in Concourse:

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

This is the build.yaml

---
platform: linux

image_resource:
  type: docker-image
  source:
    repository: karlkfi/concourse-dcind
    tag: latest

inputs:
  - name: pipeline_repo
  - name: src_repo
  - name: release_artifacts

outputs:
  - name: src_repo

params:
  dockerfile_location:
  svc_name:
#  git_comitt_sha:

run:
  path: pipeline_repo/tasks/docker/build.sh

It doesn't even have the chance to connect to Docker to run the commands in the build.sh.

Am I missing something? Is your entrypoint.sh required?

Thanks =]

Latest version of Docker Engine is 18.06.

Hey, I'm getting this error mounting an nginx conf file into my container. I suspect the source of this error is the fact that I am running the docker-in-concourse commands on the docker daemon mounted from my host machine (see -H socat:1234) - I can't tell why this 'not a directory' error is occurring though.

docker-compose (concourse deployment) (to show how the daemon is mounted)

  socat:
    image: alpine/socat:1.0.3
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    command:
      - TCP-LISTEN:1234,fork
      - UNIX-CONNECT:/var/run/docker.sock

docker-compose (pipeline'd project)

      volumes:
          - ./nginx.conf:/etc/nginx/nginx.conf:ro
