are there any deis with ruby or rails application tutorials? I didn't see any, but for getting people from heroku, it would be great to see some tutorials so people can easily migrate.

on the minimum cluster of 3 nodes with 2 gb each, what is the minimum amount of apps that could be run?

we have a bunch of sample applications which we run nightly integration tests against. As for application tutorials themselves, we have the buildpack[1] and the dockerfile[2] workflows.

I can't give you an answer on how many apps you can run on a 3x2GB cluster. It really depends on how much memory/clock cycles your apps require.

how many small 50 mb sinatra ruby apps?
