missing group in pipelines run leads to docker failure

[Nathan T]

hey guys. i have a weird problem w/ jenkins 2.52, i added the jenkins user to the docker group, and when i run `id` locally, i get `uid=109(jenkins) gid=114(jenkins) groups=114(jenkins),998(docker)` (which is fine)

but when `id` is run in the jenkins pipline, i get `uid=109(jenkins) gid=114(jenkins) groups=114(jenkins)`

so I get: `Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock` via the jenkins pipeline run, but docker is fine when run as the jenkins user locally on the box...

any ideas?

[Nathan T]

ok, but it's fine if docker is the primary group?

This came in handy for me. Pls have it a try.
