Fail to start jenkins with no permission in entrypoint?

[NewbMiao]

Info:

• Docker version ($ docker --version): Docker version 17.03.1-ce, build c6d412e
• Laradock commit ($ git rev-parse HEAD): 81053c0
• System info (Mac, PC, Linux): Mac
• System info disto/version: Darwin newbmiaodeMacBook-Pro.local 16.4.0 Darwin Kernel Version 16.4.0: Thu Dec 22 22:53:21 PST 2016; root:xnu-3789.41.3~3/RELEASE_X86_64 x86_64

Issue:

RT
When start jenkins use docker-compose start jenkins it failed
and i get log using docker-compose logs jenkins

$ docker-compose logs jenkins
Attaching to laradock_jenkins_1
jenkins_1             | [FATAL tini (6)] exec /usr/local/bin/jenkins.sh failed: Permission denied

obviously, it caused by no permission
so i simply change dockerfile like this:

# use root to set permission and group of jenkins.sh
USER root
COPY jenkins-support /usr/local/bin/jenkins-support
COPY jenkins.sh /usr/local/bin/jenkins.sh
RUN chown -R ${user} /usr/local/bin/jenkins.sh && chmod +x /usr/local/bin/jenkins.sh
USER ${user}
ENTRYPOINT ["/bin/tini", "--", "/usr/local/bin/jenkins.sh"]

now it seems ok.

and there is some line comfused me:

# Add jenkins to the correct group
# see http://stackoverflow.com/questions/42164653/docker-in-docker-permissions-error
# use "getent group docker | awk -F: '{printf "%d\n", $3}'" command on host to find correct value for gid or simply use 'id'
ARG DOCKER_GID=998

does this GID right for every environment?

UPDATE:
For mac, there is no docker group default, and i finally use below solution.
use sudo to run docker in host

Or
add daemon group for jenkins

docker for mac is use daemon group for docker
use echo $(ls -al /var/run/docker.sock | awk '{print $4}')

#Why install docker twice?Does this cause no docker command in jenkins?

[NewbMiao]

Try to use docker outside jenkins-docker with -v \var\run\docker.sock: \var\run\docker.sock
Cause docker in docker share volume is totaly bad idea!
It cost me half day to figure it out!

It solve my problem.

cd laradock && chown -R 1000:1000 jenkins/jenkins_home
