This repository will contains all learnings about hibernate , JPA and Spring Data JPA
- Run docker container with same volume to creating multiple database for persitent even container has been deleted all data will be remained same
docker run --detach --env MYSQL_ROOT_PASSWORD=myrootsqlpass --env MYSQL_USER=jd-user --env MYSQL_PASSWORD=jdsqlpass --env MYSQL_DATABASE=jddb --name jdmysqlcontainer --publish 3306:3306 --network=web-application-mysql-network --volume mysql-database-volume:/var/lib/mysql mysql:latest-
currently one user jd-user and two schemas are running jddb and myblog are running
-
When we required to create new database then create new database from root user using sql query or mysqlwork bench
-
In order to get same databses and data use the same command to run the container which is step1
-
