Ratel cannot connect to port 8082 (Docker doesn't listen)

Hi there!

My port 8080 was already used by another DB I’m testing so I change docker.composer to use port 8082, but it’s not working in ratel, I tried localhost and 127.0.0.1 with many possibilities. /api, etc)

Error:
Not connected (http://localhost:8082/)

docker-composer.yml:

  GNU nano 2.5.3                            File: docker-compose.yml

I just noticed it’s not listening on ipv4.

Hmm, I never used docker before neither I’m starting to see the benefit of it though, so excuse me if this is a noob mistke.

I think you server ports config should have 8082:8080 instead of 8082:8082 as the server is still running on port 8080, but you want to bind it to port 8082.

So external:internal.
Darn! You’re good! It’s working - thank you so much!
