A JBoss Project
Red Hat

Latest posts

We are extremely pleased to announce that the preview release of the Red Hat OpenShift Connector for JetBrains products (IntelliJ IDEA, WebStorm,…​.) is now available. You can download the OpenShift Connector plugin from the JetBrains marketplace or install it directly from the plugins gallery in JetBrains products.

This article provides describes the features and benefits of the plugin and provides installation details. It also provides a demo of how using the plugin improves the end-to-end experience of developing and deploying Spring Boot applications to your OpenShift cluster.

Benefits of using the extension

Red Hat OpenShift is a container application platform that brings the power of Kubernetes and containers to the enterprise. Regardless of the applications architecture, OpenShift lets you easily and quickly build, develop, and deploy in nearly any infrastructure, public or private.

Therefore, whether it’s on-premises, in a public cloud, or hosted, you have an award-winning platform to get your next big idea to market ahead of your competition.

Using OpenShift Connector, you can interact with any Red Hat OpenShift including a local instance of OpenShift clusters such as minishift/Red Hat Container Development Kit. Leveraging the OpenShift Application Explorer view, you can improve the end-to-end experience of developing applications.

The plugin enables you to perform all this directly using JetBrains products (IntelliJ IDEA, WebStorm,…​.) on Windows, Linux and macOS platforms and removes the complexity of memorizing some fairly complicated CLI commands.

Once the OpenShift Connector is installed, a new panel, the OpenShift view, is enabled in the Explorer panel. Then, you can access the view and connect to a running OpenShift cluster to perform the required operations.


You can see a live demo of the plugin here:

Below are the steps to run the demonstration by yourself


First, you will need to install any JetBrains product (IntelliJ IDEA, WebStorm,…​.) 2018.1 or later.

To install the plugin, bring up the plugins configuration dialog: File → Settings → Plugins:

ij openshift connector

In the search bar, enter OpenShift and click on the OpenShift Connector by Red Hat item:

ij openshift connector1

Click the Install button:

ij openshift connector2

Once the plugin has been downloaded, click the Restart IDE button.

Once the IDE has been restarted, mouse over the Views icon in the bottom left area:

ij openshift connector3

Select the OpenShift item:

ij openshift connector4

The plugin in action

Connecting to your OpenShift instance

  1. If you’re working locally, start the local OpenShift instance using minishift/Red Hat Container Development Kit

  2. You then need to log in to the running OpenShift cluster: right click on the cluster URL tree node and select Log in to cluster.

ij openshift connector5

Enter developer in the Username field and any value in the Password field and press the OK button:

ij openshift connector6

Import the project to be deployed

Before we work with our local cluster, first import our application source code. We will use a simple Spring Boot application whose source code is located at https://github.com/openshift-evangelists/Wild-West-Backend.

In order to import the application, use the File → New → Project from Version Control → Git:

ij openshift connector7

Enter https://github.com/openshift-evangelists/Wild-West-Backend in the URL field and press the Clone button.

Create a project for the application

The application will be hosted in an OpenShift project (similar to Kubernetes namespaces). For more information about OpenShift projects, see the official documentation

In the OpenShift view, right click on the cluster node (the one with the URL) and select New Project:

ij openshift connector8

Enter spring-boot in the Project name and press the OK button:

ij openshift connector9

Create the application

In the spring-boot node, right click and select New Application:

ij openshift connector10

Enter springbootapp in the Application name field and press the OK button:

ij openshift connector11

Deploy the component

In the springbootapp node, right click and select New Component:

ij openshift connector12

Enter backend in the Name field:

ij openshift connector13

Press the Browse button:

ij openshift connector14

Select the Wild-West-Backend project and press the OK button:

ij openshift connector15

In the Component type field, select the java item:

ij openshift connector16

Press the OK button. A new terminal window will be displayed and the component will be deployed to your local cluster.

ij openshift connector17
On IntelliJ IDEA 2018.3 or 2018.3 based JetBrains products, the terminal window will be automatically closed when the underlying command process is terminated. We are working for a workaround but we recommend to use previous versions until the plugin will be updated. See the issue for more information

Once deployed, the component will appear in the OpenShift view:

ij openshift connector18

Testing the component

Let’s try to test the deployed application in a browser. In the OpenShift view, right click the backend node and select Open in Browser:

ij openshift connector19

As no URL has been set up for our component (to allow external access to our application), press the OK button:

ij openshift connector20

As our application is exposing several ports, we need to select one: choose the 8080 one and press the OK button. The following brower window should be displayed:

ij openshift connector21

Don’t worry, the error message is displayed because our application has no mapping for the root. Append /egg in the URL bar in the browser window and press the ENTER key:

ij openshift connector22

Inner loop

In the following scenario, we will modify locally the application source code and verify that the modification is broadcasted immediatly to the cluster. Let’s switch our application in watch mode so that every local modification is sent to the cluster:

In the OpenShift view, right click the backend node and select Watch:

ij openshift connector23

Now, in the Project view, open the src/main/java/com/openshift/wildwest/APIController.java file:

ij openshift connector24

Modify the egg method:

	public String easterEgg() {
		return "Every game needs an easter egg!!";

with the following content:

	public String easterEgg() {
		return "A change from inside my ide";

Refresh the browser window and you should see the following output:

ij openshift connector25

Happy to announce 4.11.0.AM1 (Developer Milestone 1) build for Eclipse 2018-12.

Downloads available at JBoss Tools 4.11.0 AM1.

What is New?

Full info is at this page. Some highlights are below.

Server Tools

EAP 7.2 Server Adapter

A server adapter has been added to work with EAP 7.2.

OpenShift 3

New OpenShift connection helper

When you need to defined a new OpenShift connection, you need to provide the following information:

  • cluster URL

  • username and password or token

If you’ve already logged in your cluster through the OpenShift Web Console, you can copy an oc command in the clipboard that contains both the cluster URL and your token.

So, from now, there is a new option that allows you to initialize the wizard fields from the copied oc command:

connection wizard paste

Click on the Paste Login Command button and the fields will be initialized:

connection wizard paste1
