This gist assumes you are running Postgres in an other container.

I happen to run Podman. The Postgres container is run with:

$ podman run -p 3001:3001 -p 5432:5432 --pod new:my_pod  -e POSTGRES_INITDB_ARGS=--auth-host=scram-sha-256 -e POSTGRES_HOST_AUTH_METHOD=scram-sha
-256  -e POSTGRES_PASSWORD=a  docker.io/library/postgres:13.3-alpine

This creates a new pod for easy network sharing.

$ podman run -v /some/path/to/the/root/of/your/app:/app -it --pod my_pod lucky bash

Run the container with Lucky in it. You can then go ahead there and run lucky dev.
