Jenkins wrong volume permissions

As haschibaschi stated your user in the container has different userid:groupid than the user on the host.

To get around this is to start the container without the (problematic) volume mapping, then run bash on the container:

docker run -p 8080:8080 -p 50000:50000 -it jenkins bin/bash

Once inside the container's shell run the id command and you'll get results like:

uid=1000(jenkins) gid=1000(jenkins) groups=1000(jenkins)

Exit the container, go to the folder you are trying to map and run:

chown -R 1000:1000 .

With the permissions now matching, you should be able to run the original docker command with the volume mapping.

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
