Question Release port 5432 for internal use (localhost)

[Émerson Felinto]

I tried to create a docker instance however it needs access to a service that uses port 5432 as you can see in the print below.



From what I understand about the problem I need to free port 5432 for internal use (localhost) but how do I do this on the firewall. Which rules should I add?

It's not able to connect as there is nothing running on the Docker discourse container on port 5432 by default.

[root@plesk ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e559d908dfa7 bitnami/discourse "/app-entrypoint.s..." 7 minutes ago Up 8 seconds 0.0.0.0:32769->3000/tcp discourse
[root@plesk ~]# docker exec -it e559d908dfa7 bash
root@e559d908dfa7:/# lsof -i:5432

Does this mean that this Docker image is unconfigured ?
