You can try LXC containers by Ubuntu, this is what Docker was based on initially. The main difference is LXC runs an init in the container so you get a standard multi process OS environment while Docker containers are single process environments.

We have been working on Flockport [1] that supports LXC containers and provides orchestration, an app store, service discovery and repeatable builds. It's still in early preview and we have not started proper outreach but it may be worth looking at.

Ubuntu also provides the LXD project that provides some orchestration across servers.
