Self-service as Heroku

I have many projects running on Rancher with cattle. Some of this application is running once a week, just like a staging environment. However, my containers still run until the user interacts with them. A lot of CPU and memory are allocated for nothing.

Is there a way to configure load balancing for sleep and wakeup a service? Like the free Heroku feature?
