From The Docker Book: using a docker container in Jenkins

jenkins-docker.sh

IMAGE=$(sudo docker build . | tail -1 | awk '{ print $NF; }')
MNT="$WORKSPACE/.."

# patch MNT to point to the host directory
MNT=$(echo $MNT | sed -E 's|^.*jenkins_home|/Users/averchenko/Development/docker-book/jenkins/jenkins_home|')

CONTAINER=$(sudo docker run \
    -d \
    -v "$MNT":/opt/project \
    $IMAGE \
    /bin/bash -c 'cd /opt/project/workspace; rake spec')
sudo docker attach $CONTAINER  # use docker logs instead if it finishes too fast to attach
RC=$(sudo docker wait $CONTAINER)
# sudo docker logs $CONTAINER
sudo docker rm $CONTAINER
exit $RC
