Basically, all you need to do is to change /var/run/docker.sock permissions inside your container and run the docker with sudo.

I've created a Dockerfile that can be used to help:

FROM jenkinsci/blueocean:latest

USER root
# change docker sock permissions after moutn
RUN if [ -e /var/run/docker.sock ]; then chown jenkins:jenkins /var/run/docker.sock; fi
