Building things on top of docker seems like the fun, exciting thing to do these days and the promise of it is really cool. I certainly have wanted a private heroku that is not a bear to install.<p>In my ideal world, you could start with a single machine on say Digital Ocean for $5/mo. and that machine could host any number of apps, heroku style, for me until it runs out of resources. It should then be easy to move apps to a 2nd or 3rd or whatever server if I chose not to just bump up the resources on that first one. If an app needs to run multiple servers, it should handle that as well. Having reasonably fine grained control on how many machines things like a database or memcache layer was on would be nice.<p>In short, I would like something like heroku without all the extra costs of heroku. Cloud 66 comes reasonably close, but I'd like to not pay the extra service overhead. I'd rather just pay for the infrastructure. Something open source that handles this in a reasonable way would be great, but I don't know that Deis is going to be the answer.
