Permission denied error invoking Docker on Mac host from inside Docker Ubuntu container as non-root user

Question

I\'m trying to invoke docker on my OSX host running Docker for Mac 17.06.0-ce-mac17 from inside a running jenkins docker container (jenkins:latest), per the procedure described

Answer 1

Another approach that worked for me - set the uid argument to the uid that owns /var/run/docker.sock (501 in my case). Not sure of the syntax for Dockerfile, but for docker-compose.yml, it's like this:

version: 3
services:
  jenkins:
    build:
      context: ./JENKINS
      dockerfile: Dockerfile
      args:
        uid: 501
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ...

Note this is based on using a Dockerfile to build the jenkins image, so many details left out. The key bit here is the uid: 501 under args.
