This is a very simple micro service that can be built and packaged into a docker image. You should use this micro service as a template for building your own micro services.

1. Compile and package the application

   $ mvn clean package
   

2. Build the docker image

   $ docker build -t template-microservice .
   

3. Run the container

   $ docker run -p 8080:8080 template-microservice
   

4. Test the micro service

   $ curl http://localhost:8080
   Success! The Framework Training template microservices is up and running
   

To use this template you need to copy and then edit a few key files.

1. Make a new directory and copy the template

   $ mkdir ../simpleservice
   $ cp -R * ../simpleservice/
   $ cd ../simpleservice/
   

2. Edit pom.xml. Change the artifactId and name values

   <artifactId>simpleservice</artifactId>
   <name>Simple Microservice</name>
   

3. Edit Dockerfile and change the jar file name on the ADD instruction

   ADD target/simpleservice-0.0.2-SNAPSHOT.jar app.jar
   

4. Compile and package the application

   $ mvn clean package
   

5. Build the docker image

   $ docker build -t simpleservice .
   

6. Run the container

   $ docker run -p 8080:8080 simpleservice
   

7. Test the micro service

   $ curl http://localhost:8080
   Success! The Framework Training template microservices is up and running
   

8. You can now import your new micro service project into your favourite IDE and start development
