user jenkins for docker commands

[herau]

I try your slave but i can't run any docker commands.
i have this kind of message
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

How you can execute docker commands whereas the docker container only contains the jenkins user ?
Docker need a root user to be able to run docker commands right ?

my docker-compose file:

version: '2'
services:
  master:
    user: root
    image: jenkinsci/jenkins
    links:
      - slave-docker
    environment:
      - JAVA_OPTS=-Duser.timezone=Europe/Paris
    volumes:
      - ./data:/var/jenkins_home
    ports:
      - "50000:50000"
      - "8080:8080"
  slave-docker:
    image: evarga/jenkins-slave
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      #  static binay of docker
      - /home/data/docker/bin/docker:/bin/docker

In Jenkins i have created a slave

The slave container doesn't come preinstalled with Docker. It is just a Linux base image for Jenkins to be able to spin it up as a slave node. You are responsible to further customize it via scripts during boot up. It would be inappropriate to start filling in this base image with all possible supporting sub-systems. I hope this clarifies the intention of this Jenkins slave image.
