Docker installer MySQL

Procédé de construction d'Dockerfile

Créer Dockerfile

Tout d'abord, créer un mysql d'annuaire, pour stocker des choses liées à dos.

w3big@w3big:~$ mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf

répertoire de données mysql est mappé sur le chemin de stockage du fichier de configuration de conteneur de données

répertoire de journaux sera mappé sur le répertoire des journaux de conteneur de mysql

les fichiers de configuration du répertoire conf sont mappés sur le conteneur mysql fichier de configuration

Entrez le répertoire mysql créé, créez Dockerfile

Créer un miroir à travers Dockerfile, remplacez-le avec votre propre nom

w3big@w3big:~/mysql$ docker build -t mysql .

Une fois créé, nous pouvons trouver l'image que vous venez de créer dans la liste de miroir local

w3big@w3big:~/mysql$ docker images |grep mysql
