Persistence
This section will explain how an Application Server and a Database server can be used to deploy an application.
In-memory Database
docker run -it -p 8080:8080 arungupta/javaee7-holAccess at http://<IP_ADDRESS>:8080/movieplex7.
Same Host, Using Linking
docker run --name mysqldb -e MYSQL_USER=mysql -e MYSQL_PASSWORD=mysql -e MYSQL_DATABASE=sample -e MYSQL_ROOT_PASSWORD=supersecret -d mysql
docker run --name mywildfly --link mysqldb:db -p 8080:8080 -d arungupta/wildfly-mysql-javaee7
docker-machine ipSame Host, Using Compose
curl -L https://github.com/docker/compose/releases/download/1.1.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose up -d
docker-compose ps
docker-compose logs
docker-machine ip
curl http://<IP_ADDRESS>:8080/employees/resources/employees/Different Hosts, Using IP Address
Persistence on Data-only Containers
docker create --name mysql_data -v /var/lib/mysql mysql
docker run --name mysqldb --volumes-from mysql_data -v /var/lib/mysql:/var/lib/mysql -e MYSQL_USER=mysql -e MYSQL_PASSWORD=mysql -e MYSQL_DATABASE=sample -e MYSQL_ROOT_PASSWORD=supersecret -it -p 3306:3306 mysqlClustering
