Building Web Services with Java EE 8
Section 1: Getting Started

Now you can build the project and deploy the final artifact to your Payara Server.

$ mvn clean package

Containerization

To containerize our microservice, we have to write a Dockerfile. See the step-04 branch for the final result.

First, we need to decide which container base image to use. Have a look at Docker Hub. The two options presented here are:

Add a Dockerfile to the base directory of this project and add the following content:

FROM payara/server-full:5.181
COPY target/hello-javaee8.war $DEPLOY_DIR

To build the image and run it as a container, open a command prompt and issue the following shell commands:

$ mvn package

$ docker build -t hello-javaee8:1.0-full .
$ docker run -it -p 8080:8080 hello-javaee8:1.0-full

You should now be able to access the web service under the IP of you Docker host.

Next, we want to use the Payara Micro base image instead. Add the following content to the Dockerfile:

FROM payara/micro:5.181
COPY target/hello-javaee8.war /opt/payara/deployments

To build the image and run it as a container, open a command prompt and issue the following shell commands:

$ mvn package

$ docker build -t hello-javaee8:1.0-micro .
$ docker run -it -p 8080:8080 hello-javaee8:1.0-micro

Again, you should now be able to access the web service under the IP of you Docker host.
