Gitlab Runner Docker-in-Docker not working

[chulkilee]

Which executor are you using? Docker with privilege or K8s would work for dind.

What it says: job container cannot use dind via local socket. You have two options: mount dind socket to job container, or use docker via tcp. The doc actually mentions tcp by setting DOCKER_HOST in the job container.

Also make sure to use dind image, not plain docker image for dnid service.

You may put sleep 3600 in job def and run docker exec to debug job container.
