As a relative beginner to Docker at home, the biggest issue I've had is that there is a presumption that everything is HTTP. I wanted to run two apps in two Docker containers that both wanted UDP on the same port and couldn't do it. Docker lets you use multiple IPs but apparently you can only use a single port for any app on a single host. Tedious.
