Where are Docker containers edited?

Question

Docker

https://docs.docker.com/compose/wordpress/
1. Installed docker
2. Installed docker compose
3. According to the guide, I used a yml file in my home directory and launched docker compose
And where are the wordpress engine files now available to me so that I can use it edit and everything else?
Moreover, it is not clear what to do next? To start the project
The command worked, but how to start the project is not clear

Answer 1

read how to install a little, read more how to use ;)
docker ps will show running containers
docker exec -ti container_name bash will "go" inside the container.
also in ready-made containers there are environment variables, they are edited in the dokeycompose file, the list of variables on the home page of your container;)
