Basic Usage

To start Jenkins with the latest version:

ID=$(docker run -d -p 8080:8080 itzg/jenkins)

At a later time, you can upgrade by restarting the container:

docker stop $ID
docker start $ID

Attaching host directory to Jenkins home directory

The Jenkins home directory is attachable at /data, so attaching to a host volume would be:

ID=$(docker run -d -p 8080:8080 -v /SOME_HOST_DIR:/data itzg/jenkins

As with any Docker container, you can run a shell within the running container:

docker exec -it $ID bash

A more realistic example is installing git, openjdk-7-jdk, etc:

docker exec $ID apt-get update
docker exec $ID apt-get install -y git openjdk-7-jdk

and then Configure the JDK in Jenkins:
