### Summary Docker volumes not mounted when using docker:dind ### Steps to reproduce With the following *.gitlab-ci.yml* file, the Docker command should return `test_file`, showing that the */mnt* directory was mounted successfully. It returns nothing. image: docker:latest services: - docker:dind stages: - test docker: stage: test script: - touch /mnt/test_file - docker run -v /mnt:/mnt ubuntu ls /mnt The Docker image gitlab/dind works, but it is based on jpetazzo/dind, which is obsolete and based on the very old Ubuntu Trusty (from 2014). So mounting the volumes work, but many other things that depend on newer technologies fail. ### Example Project In the following sample project, I'm using the shared CI runners, but other people from #gitlab on freenode tested it with private runners, and have the same problem. https://gitlab.com/teresaejunior/my-awesome-project/blob/master/.gitlab-ci.yml ### Relevant logs and/or screenshots https://gitlab.com/teresaejunior/my-awesome-project/-/jobs/44977716 ### Output of checks This bug happens on GitLab.com (but also on private runners, as shown by other users).
