IBM Bluemix used to have a free tier for containers, which you could use to run tiny apps quite easily and cheaply, using the native Docker CLI. They've since moved to Kubernetes and still have a free tier, but not sure how that works. I'd probably recommend a DigitalOcean VPS though. Cheap, very stable (had a couple VPS for a year with 100% uptime, as far as I know), stellar support and a lot of new functionality being added lately - block storage, firewall, load balancing. DO is one of the best services I've paid for. Disclosure: I used to work at IBM about a year ago, in the container service team.
