How to wrap existing postgresql db in docker container?

Question

PostgreSQL

Good afternoon.
I have an app.jar application which, when installed, creates a user and password in posgtresql. At this point postgresql should just be installed and running.
I managed to push and run the application in a container, but it needs postgres.
How can you push the existing database into a container and explain to the application where to look?

Answer 1

You can't stuff bases into containers. And the DBMS is not desirable .

Answer 2

Raise the container with the base, fill it with a dump, in the application settings, specify where to connect.
Within docker-compose, this is convenient to do.
