Cannot connect to database on Docker-CodePudding

I have created database on docker: docker run --name database -e POSTGRES_PASSWORD=password -d -p 5436:5436 postgres Created some database inside:

createdb database

Also created superuser. Now I am trying to connect from localhost:

psql -h localhost -p 5436 -U postgres

After that I get following error:

 psql: The server closed the connection unexpectedly
        This probably means that the server has terminated abnormally
        before or while processing your inquiry.

Ports are connected:

CodePudding user response：

In your case, you are trying to expose 5436 and map with your host port 5436, but that might need to use -p 5436:5432 because Postgres uses port 5432 as the default port.

docker run --name database -e POSTGRES_PASSWORD=password -d -p 5436:5432 postgres

There is some description from Container networking

-p 8080:80：Map TCP port 80 in the container to port 8080 on the Docker host.
