When i try to run the container with:

docker compose up

All my script files run fine, but the installation of pandas module was not going well. The interpreter raises an error specifying that pandas module was not found, but, i already created a file “requirements.txt” with pandas line in there, and that’s my docker-compose.yaml file:

Then my scrip run and is not waiting till the databases services start first.

    image: postgres
