Non-unRAID Docker management recommendation?

I figured this was too off topic to ask anywhere other than the lounge.

I'd not gotten into Docker use until a couple weeks ago with the unRAID 6 final launch. I'm absolutely loving how Docker works inside of unRAID (and all the other v6 unRAID improvements), and wanted to setup another server or two for Docker use completely outside of unRAID (in another location, and have no real use for the storage side of unRAID). I'm quickly realizing that it's a big ol' Docker world out there with tools for managing huge farms of servers, containers and multi-containers. I've been struggling to find something as clean and simple for managing containers as the Dynamix UI is in unRAID. Is there any good (preferably open source) web-based management UI's for managing a small number of containers (a dozen or so, on one or two servers) that is simple and user friendly, such as unRAID's implementation is? I've got an Ubuntu 14.04 box with the Docker engine successfully running on it, and just looking for a good web UI. Figured that with all the folks here that have been messing with the Docker components throughout all the v6 betas, there might be a couple of you out there that are well versed in the platform and tools.

Thanks
