  plan:
  - get: source
    trigger: true
  - task: runDockerCompose
    privileged: true        # required
    file: source/path_to_task_definition/taskDefinition.yml
    
... 

Task definition (e.g. taskDefinition.yml):

platform: linux

image_resource:
        type: docker-image
        source: {
        repository: quay.io/cosee-concourse/dind,
        tag: "latest" }

run:
        path: sh
        args:
        - -exc
        - |

          start_docker                        # required
          cd source/path_to_dockercompose_yml
          docker-compose up -d
          # execute your tasks e.g.
          docker-compose -f docker-compose-runTasks.yml run testservice echo "Hello World"
          rc=$?                               # exit code of testservice
          docker-compose down                 # required
          exit $rc
