How to set up a connection to a remote PostgresSql database from a Docker Container?

Question

PostgreSQL

Good afternoon!

Made my application on spring-boot . I compiled a build and put it in Docker-Hub . I'm trying to start this application on another server.

But I get just such an error:

Locally, the application naturally works. I understand that this error is due to the fact that I cannot connect to the database and thereby create the correct beans.

Please tell me how I can set up Docker or forward url-bases through NGNIX to make the application work on Docker .

Thank you very much in advance!
