GitlabCI run docker review app

Question

I have several php apps with similar requirements, dockerized gitlab runner and one docker image for my apps.

What is the best solution for autostart review apps?

I started runner with connected docker.sock and additionaly added volume with my projects /home/devenv/ for runner attached in gitlab runner config.toml:

  [runners.docker]
    tls_verify = false
    image = "docker:latest"
    privileged = true
    disable_cache = false
    volumes = ["/cache", "/home/devenv:/home/devenv"]   

Test and build works fine, using image: myrepo.com/group/image in .gitlab-ci.yml

Then my deploy section fails with error. Deploy section:

deploy to review:
  image: docker:latest
  services:
    - docker:dind
  stage: deploy
  script:
    - rm -rf /home/devenv/$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME
    - mkdir /home/devenv/$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME
    - cp -r ./* /home/devenv/$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME/
    - docker stop $CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME
    - docker rm $CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME
    - docker run -d --env ENDLESS_RUN="1" --env VIRTUAL_HOST="$CI_BUILD_REF_NAME.$CI_PROJECT_NAME.$CI_PROJECT_NAMESPACE.e.mydomain.com" --name "$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME" -v /home/devenv/$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME/httpdocs:/home/web/httpdocs -v /home/devenv/$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME/logs:/var/logs myrepo.com/group/image
    - docker exec $CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME-$CI_BUILD_REF_NAME cd /home/httpdocs/ && npm install && bower install && gulp build
  environment:

  except:
    - master

DIND doesn't allow mounting volumes from one container into another. For what you're trying to do you'll have to share the host docker service with the container
