Case - Genbrug af en allerede oprettet Docker-volumen
Hvis du stopper Sejl med sail down , forbliver datavolumen på Docker-værten uden at blive slettet.
Når Sail er stoppet, skal du bruge sail down -v for at slette de eksisterende Docker-volumendata.
Første sail up , DB_DATABASE=smed
Første gang du starter Sail, oprettes en volumen på Docker-værten.
grep DB_DATABASE .env
DB_DATABASE=forge
docker volume ls
DRIVER VOLUME NAME
sail up -d
Creating network "test_sail" with driver "bridge"
Creating volume "test_sailmysql" with local driver
Creating volume "test_sailredis" with local driver
Creating test_mailhog_1 ... done
Creating test_mysql_1 ... done
Creating test_redis_1 ... done
Creating test_laravel.test_1 ... done
docker volume ls
DRIVER VOLUME NAME
local test_sailmysql
local test_sailredis
sail mysql
mysql> show databases;
| forge |
Men når jeg afslutter Sail, slettes Docker-beholderen, men volumen slettes ikke.

local test_sailredis
Anden sail up , DB_DATABASE=test
Hvis du starter en anden Sail i det samme mappenavn, vil den allerede oprettede Docker-volumen blive genbrugt.
grep DB_DATABASE .env
DB_DATABASE=test
sail up -d
Creating network "test_sail" with driver "bridge"
Creating test_mysql_1 ... done
Creating test_redis_1 ... done
Creating test_mailhog_1 ... done
Creating test_laravel.test_1 ... done
docker volume ls
DRIVER VOLUME NAME
local test_sailmysql
local test_sailredis
Da data findes i test_sailmysql , som er den volumen, der blev oprettet i den første kørsel, udføres en ny databaseoprettelsesopgave ikke.
