Så installerar du MySQL i en Docker-container – steg för steg

Kör MySQL i Docker – enkel guide

Först behöver du Docker på plats. Kolla den här guiden för Ubuntu:
Installera Docker på Ubuntu.

Starta en MySQL-container i bakgrunden. Root-lösenordet blir "test". Containern rensas automatiskt när den stannar.

docker run --rm -it -e MYSQL_ROOT_PASSWORD=test -d mysql

• -d: Kör i bakgrunden och visa container-ID.
• --rm: Tar bort containern vid stopp.

Kolla aktiva containrar

docker ps
