Command for loading postgres through docker?

Question

Does anyone know the command for loading postgres through docker? Here is the recommended command on their documentation:

docker run -it --rm --network some-network postgres psql -h some-postgres -U postgres

Forgive the naive question, how do you find what values for "some-network" are supposed to be and what values "some-postgres" is supposed to be?

Answer 1

To be precise, each flag has a own meaning in the docker run command.

docker run -it --rm --network some-network postgres psql -h some-postgres -U postgres

-i: Keep STDIN open even if not attached

-t: Allocate a pseudo-TTY

--rm: Automatically remove the container when it exits

--network: Connect a container to a network. You can ignore this if you are running a standalone postgress container or you can use host mode if you want the container to use host networking. For more information and modes. Check below article.
