[screenshots to follow]

• I've freshly installed Jenkins 2.407.3 and docker-plugin version 1.1.4.

• There is a "cloud" configured to reach out to my docker host, and a single agent template both defined in "Jenkins" > "Configure System" > "Cloud"
• A single test job is defined. Checking the "Define a Docker template" box makes a few dialogs appear with no description.

I don't know if these dialogs are actually hooked up to anything, and it's making diagnosing a separate issue (only one docker image will be spun up at a time regardless of the job being set to be concurrent) difficult
