问题 I've read Can anyone explain docker.sock to understand what /var/run/docker.sock does, but its use in GitLab CI's Use Docker socket binding has me confused. Here is their example command for the gitlab-runner registration: sudo gitlab-runner register -n \ --url https://gitlab.com/ \ --registration-token REGISTRATION_TOKEN \ --executor docker \ --description "My Docker Runner" \ --docker-image "docker:19.03.12" \ --docker-volumes /var/run/docker.sock:/var/run/docker.sock I see two places that

问题 This question is different from the following questions: Docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock Because they didn't consider jenkins to be installed as docker container, here I don't have jenkins user to give that user access to this file. And also from this one docker.sock permission denied Because I don't know which user I got this error for, Here the user root has access to this file but the error happened again.

问题 I would like to network with a child docker container from a parent docker container, with a docker-in-docker setup. Let's say I'm trying to connect to a simple Apache httpd server.
