Jenkins Docker Container cannot access docker.sock

Question

I deployed a standard Jenkins Docker image using docker-compose and this configuration:

deployer:
  image: jenkins
  volumes:
    - "/mnt/jenkins:/var/jenkins_home"
    - "/var/run/docker.sock:/var/run/docker.sock"
  ports:
    - "2375:2375"
    - "8080:8080"
    - "50000:50000"

After reading the many SO questions I tested, Root was added to the docker user group with help gpasswd -a ${USER} dockerand confirmed that the user inside the container is root c docker exec jenkins_deployer echo ${USER}.

When I try to add Docker access to the Jenkins user interface using "Docker URL = unix: ///var/run/docker.sock", I get the error message " org.newsclub.net.unix.AFUNIXSocketException: Permission denied (socket : /run/docker.sock) "

How can I give Jenkins access to docker.sock to automatically deploy Docker containers?
