What does Running post build plugin 'Docker Container Cleanup' actually do?

[Aditya Chugh]

Looks like I am having some issues part of my build plan where:

error    16-Nov-2017 17:28:23    Failed to execute plugin 'Docker Container Cleanup' with error: Error running Docker remove command

Clearly this is a Post Build plugin. But I never setup any plugins - so how can I debug this? I cannot find any resources on my self hosted Bamboo regarding this.

Please advice
