Hello I can not dockerize my django app because I got an error -
listen tcp4 0.0.0.0:5433: bind: address already in use
From the other hand, when I "kill" 5433 port in ubuntu terminal I get this error
Is the server running on host "localhost" (::1) and accepting
web_1 | TCP/IP connections on port 5433?
What can I do to solve this problem and dockerize successfully my app? Dockerfile
FROM python:3
RUN adduser --system --no-create-home django

You should use "db" as host here. In a docker-compose setup each service is started in a separate Container and the /etc/hosts
config of all containers is modified so, that each container can find the other containers via the service names.

I`ve got it!. In 'localhost" port of postgres was 5433 but for 'db' as HOST it was default, 5432.
