Docker image for Jenkins agents connected over SSH

A Jenkins agent image which allows using SSH to establish the connection. It can be used together with the SSH Build Agents plugin or other similar plugins.

See Jenkins Distributed builds for more info.

Running

To run a Docker container

docker run jenkins/ssh-agent "<public key>"

You'll then be able to connect this agent using the SSH Build Agents plugin as "jenkins" with the matching private key.

How to use this image with Docker Plugin

To use this image with Docker Plugin, you need to pass the public SSH key using environment variable JENKINS_AGENT_SSH_PUBKEY and not as a startup argument.

In Environment field of the Docker Template (advanced section), just add:

JENKINS_AGENT_SSH_PUBKEY=<YOUR PUBLIC SSH KEY HERE>

Don't put quotes around the public key. You should be all set.
