docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
I'm getting this whenever I try to run Docker inside Jenkins. The machine was installed using the Bitnami Jenkins image. I have exhausted every troubleshooting option I can think of in an effort to solve what should be a simple permissions issue, but keep coming up empty.
I have attempted all the suggestions here at this Stack Overflow thread. I have attempted adding jenkins, bitnami, azureuser and anyone else on the system that looks like they might run Docker to the docker group using sudo usermod -a -G docker <user>.
I can sudo su - jenkins and docker run hello-world without issues.
Yet, still, no matter what I do, I am reduced to this error.
sudo usermod -aG docker $USER does nothing.
sudo usermod -a -G docker bitnami does nothing.
sudo usermod -a -G docker jenkins does nothing.
sudo usermod -a -G docker literallyanyusericanthinkof does nothing.
Rebooted/restarted hundreds of times now, no help.
I can run Docker in literally any other context on the machine, but Jenkins still refuses to run it. I am at my whits end getting this to work. I've configured at least two other Jenkins servers to do this before, but this one is giving me grief and I have no idea why.
Can anyone point me in the right direction?
