All really useful thank you.

It looks like i am having the same issue with the error can't reach '/uploads/default...

The next line of my log file is
Started GET "/posts/950" for 127.0.0.1 at 2020-07-07 08:24:05 +0000

Any ideas why mine is trying through the loopback IP and not the newly named container or the container local IP ?
