We gave both Dokku and Flynn a try earlier in 2014. Dokku ended up just being too simple for our needs—we're deploying to a cluster, not a single machine. Flynn still felt too immature and definitely isn't optimized for microservice architectures. Instead, we hired progrium (the creator of Dokku) to help us build out a Fleet & CoreOS based deployment infrastructure. With a couple custom bash scripts, all run through CircleCI, it's worked pretty well so far.
