Jenkins: No Docker binary installed?

[shakefu]

Is this an intentional thing that should be configured? I can't seem to find anyone mentioning that the Jenkins Catalog image doesn't have docker installed, nor does it seem to want to allow me to install it from a shell.

Is there a best practice way for enabling the Jenkins Catalog to run/build/push Docker images?

Answering my own issue:

Apparently the two best approaches currently are either:

1. Build a custom Docker image for the Jenkins master with the Docker binaries.
2. Use a slave image (via Swarm plugin) that has Docker installed.
