docker - Jenkins wrong volume permissions

Question

I have a virtual machine hosting Oracle Linux where I've installed Docker and created containers using a docker-compose file. I placed the jenkins volume under a shared folder but when starting the docker-compose up I got the following error for Jenkins :

jenkins | touch: cannot touch ‘/var/jenkins_home/copy_reference_file.log’: Permission denied jenkins | Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions? jenkins exited with code 1

Here's the volumes declaration

  volumes:
    - "/media/sf_devops-workspaces/dev-tools/continuous-integration/jenkins:/var/jenkins_home"

Answer 1

The easy fix it to use the -u parameter. Keep in mind this will run as a root user (uid=0)

docker run -u 0 -d -p 8080:8080 -p 50000:50000 -v /data/jenkins:/var/jenkins_home jenkins/jenkins:lts
