# Fabric8 Maven Plugin + Kompose:

Let's deploy a Springboot Java application with Compose file using Fabric8 Maven Plugin to Kubernetes or OpenShift.

##### Requirements

- Linux or MacOS or Windows
- JDK 1.7+ - [JDK Quick Installation Guide](http://openjdk.java.net/install/)
- Maven 3.x+ - [Maven Installation Guide](http://www.baeldung.com/install-maven-on-windows-linux-mac)
- Kompose - [Kompose Installation Guide](/installation)

**1. Clone the example project from GitHub**

```bash
$ git clone https://github.com/piyush1594/kompose-maven-example.git
```

Change current directory to `kompose-maven-example` directory.

```bash
$ cd kompose-maven-example
```

**2. Add Fabric8 Maven Plugin to your project**

```bash
$ mvn io.fabric8:fabric8-maven-plugin:3.5.28:setup
```

Add the Fabric8 Maven Plugin configuration to `pom.xml` of project. `pom.xml` is manifest or deployment descriptor file of a maven project.

**3. Install Kompose through Maven**

```bash
$ mvn fabric8:install
```

This command installs the `kompose` on the host.

**4. Configure Fabric8 Maven Plugin to use a Compose file**

```bash
<plugin>
  <groupId>io.fabric8</groupId>
  <artifactId>fabric8-maven-plugin</artifactId>
  <configuration>
    <composeFile>path for docker compose file</composeFile>
  </configuration>
  <executions>
    <execution>
      <goals>
        <goal>resource</goal>
        <goal>build</goal>
      </goals>
    </execution>
  </executions>
</plugin>
```

Add the `<configuration>` and `<executions>` sections to `pom.xml` as shown in above `pom.xml` snippet. Update the `<composeFile>` to provide the relative path of Compose file from `pom.xml`

**5. Deploy application on Kubernetes or OpenShift**

Make sure that Kubernetes/OpenShift cluster or Minikube/Minishift is running. In case, if anything of this is not running, you can run Minishift to test this application by using the following command.

```bash
$ minishift start
```

Below command deploys this application on Kubernetes or OpenShift.

```bash
$ mvn fabric8:deploy
```

Now that your service has been deployed, let's access it by querying `pod`, `service` from Kubernetes or OpenShift.

```bash
$ oc get pods
NAME                                    READY     STATUS      RESTARTS   AGE
springboot-compose-1-xl0vb       1/1       Running     0          5m
springboot-compose-s2i-1-build   0/1       Completed   0          7m
```

```bash
$ oc get svc
NAME                        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
springboot-compose   172.30.205.137   <none>        8080/TCP   6m
```

Let's access the Springboot service.

```bash
$ minishift openshift service --in-browser springboot-compose
Created the new window in existing browser session.
```

It will open your application endpoint in default browser.
