Demo Spring Boot application running inside docker container linked with MySQL container

Assume you already have Docker installed. See https://docs.docker.com/installation/.

First, clone the project and build locally:

git clone https://github.com/jiwhiz/spring-boot-docker-mysql.git
cd spring-boot-docker-mysql
mvn clean package docker:build

Run MySQL 5.6 in Docker container:

docker run --name demo-mysql -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=demo -e MYSQL_USER=demo_user -e MYSQL_PASSWORD=demo_pass -d mysql:5.6

Check the log to make sure the server is running OK:

docker logs demo-mysql

Run demo application in Docker container and link to demo-mysql:

docker run -p 8080:8080 --name demo-app --link demo-mysql:mysql -d jiwhiz/spring-boot-docker-mysql

You can check the log by

docker logs demo-app

Open http://localhost:8080 in browser and you should see the message. If you are using Boot2Docker in Mac OSX, find ip by boot2docker ip and replace localhost to boot2docker ip.
