Unable to use a port other than 5432

[owais]

Here is my docker compose:

services:
  test-db:
    image: postgres:18.1
    ports:
      - "5433:5433"
    volumes:
      - pgdata-test:/var/lib/postgresql
    environment:
      POSTGRES_DB: test 
      POSTGRES_USER: test
      POSTGRES_PASSWORD: password
    command: -p 5433

volumes:
  pgdata-test:

Docker ps shows port forwarded

❯ docker ps

Trying to connect from the host:

❯ psql -h localhost -U test -d test -p 7433
psql: error: connection to server at "localhost" (::1), port 7433 failed: Connection refused
	Is the server running on that host and accepting TCP/IP connections?
connection to server at "localhost" (127.0.0.1), port 7433 failed: Connection refused
	Is the server running on that host and accepting TCP/IP connections?

Now if I change the port to 5432, everything will work as expected.

Originally I was trying to run the DB on 5432 and only map the container port to 5433 but that didn't work either so I tried to also change the port postgresql binds to but nothing seems to work.

The issue went away after I restarted my docker VM (colima) so looks like an issue with Colima instead.
