If you just want Ingress with Envoy, Heptio now has the Contour project:

The first release doesn't include Ingress support. This is something we plan on folding into our Routing API in an upcoming release. If you have opinions on how you'd like to see Ingress implemented, now is a great time to share your thoughts (in a GitHub issue, is probably best)!

Have you tried using envoy directly? That's what we run, and it works well. I'd be interested to hear about the kinds of problems you ran into (as in, "yikes, is there something we should be watching out for", not "marketing").
