4.5 Running the Lab

Building the docker image for the kafka-order microservice and start the environment.

In the previous section we implemented the microservice. Let’s build and run it.

Building

The kafka-order microservice provides a multistage Dockerfile.multistage.jvm for building the java application and creating a docker container.

Task 4.5.4 - Build docker container

Docker Version

Depending on your docker version you have to specify the output format. If you get a warning that there is no output specified for docker-container driver just add -o type=docker to your command line.

Change to base directory of this lab <PROJECT_ROOT>/code/kafka and run docker build.

1
docker build -f kafka-order/src/main/docker/Dockerfile.multistage.jvm -t microservices-lab-kafka-order:latest  kafka-order
