Run Microservices Demo with Docker Compose and Docker Machine

Docker Machine can create virtual machines to run Docker on. It supports Virtual Box but also many other technologies including several clouds. Docker Compose create all the Docker containers needed fot the systems.

To run the demo:

• Install Maven, see https://maven.apache.org/download.cgi
• Install Virtual Box from https://www.virtualbox.org/wiki/Downloads
• Install Docker Compose, see https://docs.docker.com/compose/#installation-and-set-up
• Install Docker, see https://docs.docker.com/installation/
• Install Docker Machine, see https://docs.docker.com/machine/#installation
• Go to directory microservice-demo and run mvn package there
• Execute docker-machine create --virtualbox-memory "4096" --driver virtualbox dev . This will create a new environment called devwith Docker Machine. It will be virtual machine in Virtual Box with 4GB RAM.
  • Execute eval "$(docker-machine env dev)" (Linux / Mac OS X) or docker-machine.exe env --shell powershell dev (Windows, Powershell) / docker-machine.exe env --shell cmd dev (Windows, cmd.exe). Now the docker tool will use the newly created virtual machine as environment.
• Change to the directory docker and run docker-compose buildfollowed by docker-compose up -d.

The result should be:

• Docker Compose builds the Docker images and runs them.
• Use docker-machine ip dev to find the IP adress of the virtual machine.
• You can access the application at http://ipadresss:8080/ . It has a web page with links to all other services and the Consul dashboard,
• Use docker-machine rm dev to destroy the virtual machine.
