If you are open to using an (awesome) vendor for this kind of thing, I would highly recommend taking a look at Backplane (https://www.backplane.io/). It's as simple as running a sidecar Backplane agent container along side any container that you want to route http traffic to and then shape the traffic via their API (it becomes your load balancer as well). They automatically provision Lets Encrypt certificates for your endpoints as well, so you don't have to worry about any of that. We have been using it at Mux in production for months and have been very happy with the results. Backplane also has some other nice built in features like blue/green deploys and built in OAuth support that are really nice to have out of the box.
