I am using this docker compose yaml to run both jupyter and postgress

version: "3"
services:
    jupyter:
        image: jupyter/scipy-notebook
        container_name: "my_jupyter"
        ports:
            - 8888:8888
        volumes:
            - ${PWD}:/home/jovyan/work
    postgres:
        image: postgres
        container_name: "my_postgres"
        ports:
            - 5432:5432
        environment:
            - POSTGRES_PASSWORD=mysecretpassword
        volumes:
            - pg_data:/var/lib/postgresql/data

volumes:
  pg_data:

With this I can start the containers. However the first container (I don’t know about the second) has no internet access. I tried to pip install something in the jupyter notebook and it failed

I also did

docker exec -it my_jupyter /bin/bash
(base) jovyan@9ea976cbdc32:~$ curl -I https://www.google.com
curl: (6) Could not resolve host: www.google.com

How can I solve this? is there something I am doing wrong that does not permit access to the internet?
