Crida a un servidor NextCloud (https://sub0.things.cat/):

docker run --name nextcloud0 --network net -e VIRTUAL_HOST="sub0.things.cat" -e LETSENCRYPT_HOST="sub0.things.cat" -d nextcloud:19.0.2

Accés a la consola bash del docker nextcloud0:

docker exec -it nextcloud0 bash -l

Per a obtenir la informació disponible del docker en funcionament:

docker inspect nextcloud0

Per a obtenir la IP interna del docker en funcionament:
