Initialize PostgreSQL-container with command

Question

The following Dockerfile is created:

 FROM postgres:12

 CMD [«postgres»]

And docker-compose.yml

 version: '3'
 services:
   codes:
     container_name: short_codes
     build:
        context: codes_store
     image: andrey1981spb/short_codes

     ports:
        - 5432:5432

I up docker-compose successfully. But when I try to enter in container, I receive: "Container ... is not running"

Or I use a wrong command for initializing container.

CMD [«postgres»] looks weird. What do you get from docker-compose logs codes? — Bergi

In logs I saw, that data-directory in container is not empty. I fixed this, and the problem is solved. Thank you — Jelly

You issue is due to incorrect quotes. Replacing them with proper quotes would solve it:

FROM postgres:12

CMD ["postgres"]

P.s. Your Dockerfile is essentially identical to the official postgres image, so you might as well use that in your compose yaml, unless you're planning some additional modifications later.
