I am attempting to build a docker image from a Dockerfile using a declarative pipeline in Jenkins. I've successfully added the 'jenkins' user to the docker group, and can run 'docker run hello-world' as the jenkins user manually. However, when I attempt to build through the pipeline, I can't even run 'docker run hello-world':
From the pipeline:
[workspace] Running shell script + whoami jenkins [workspace] Running shell script + groups jenkins jenkins : jenkins docker [workspace] Running shell script + docker run hello-world 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/v1.30/containers/create: dial unix /var/run/docker.sock: connect: permission denied. Manually sshing into Jenkins and switching to the 'jenkins' user:
*********@auto-jenkins-01:~$ sudo su - jenkins -s/bin/bash jenkins@auto-jenkins-01:~$ docker run hello-world Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/ Some other useful information: Jenkins is running from a VM.
