resource-manager
Puts Docker Containers to sleep and wakes them back up when they're needed.
Written in Node.js, this application acts as a HTTP reverse proxy and stops Docker containers which haven't been accessed recently and starts them again when a new request comes in. ContainerNursery also makes sure there are no more active WebSocket connections before stopping the container.
