I use nginx & docker-proxy. Because the model I copied used that setup. Having messed with it a bit, I’m understanding it more and more. Before that, the last time I messed with a web server (Apache), nginx wasn’t around. Lately, I’ve seen a similar docker setup to mine that doesn’t use docker-proxy. If I find time, I’ll probably play with that some on my dev rig.
Compatible? Should be. Identical? No (at least not always). Only identical FRU are interchangeable.
