JBoss Fuse for xPaaS - How to setup a Fuse on OpenShift Enterprise Virtual Machine with Virtual Box

I am a pure software developer deep from my bones, so when it comes to installing OpenShift, the last thing I want to do is to go through all the Linux, network setups, extra.. Luckily with OpenShift I have 2 choice, First is the easiest, just go to OpenShift Online, and by simply registering an account, you will be able to get 3 gears to play with and no hassle on setting up the openshift environment. The second option is to use the Virtual Machine provided to run a pre-set OpenShift environment, I am going to show you how to do that!

Before we begin, please make sure you have download the OpenShift 2.1 or 2.2 Virtual Machine image from Red Hat Customer Portal. Then install Virtual Box.

Start up Virtual Box, click on "New" to create a new virtual machine,


Before you start up the VM, right click on the instance you created, choose "settings... ", a configuration window will pop up, and then click on the "Network" Tab, and make sure you have selected the Bridge adapter.


Or sometimes depends on your network environment, it is easier to just setup a Host-only Adapter, this can be set under Preference,


Go to Network, setup the Adapter,
And DHCP Server,

Instead of setting to Bridge Adapter, set it up to Host-only Adapter,



Start up your VM instance when done, it might take couple of minutes to start up.  you should see a Terminal and FireFox started. type in "ifconfig" in the terminal console, here you will see the IP for this VM instance. We are going to configure the host machine to look up the DNS.


In Linux, Simply edit the /etc/resolv.conf configuration file and add the IP address of your VM instance. For example

nameserver 192.168.56.110

However, in Mac, setting the “resolv.conf” does not work, please go to System Preferences -> Network, and click on the Advance button on the right lower corner, and then on the top TAB, choose “DNS”, add the ip address of your VM instance, as we are going to use it's built in DNS resolver. And add openshife.example.com as the domain to look up.


Open up a browser in your host machine, and go to http://vm.openshift.example.com, and you will immediately ask for the  ID/PWD to logon to OpenShift. Type in demo for ID and openshift for password. There you will see the openshift pages.


Now it’s time to install the client in our host so we can interact with the OSE (short for OpenShift Enterprise). First we need to install the rhc client.

To install the RHC in Mac, simply run, (make sure you have installed Ruby in advance)
            sudo gem install rhc
for Linux or other operating system and more details please visit this page.

After successfully install the client, now it’s time to setup the rhc client, to do that simply go to your command line console, and type
            rhc setup --server vm.openshift.example.com -l demo -p openshift

In the process, you will be asked to provide a phrase for RSA key, type in anything that you will remember, and let the process keep running, in a few seconds, it will be ready to go.



Now we are ready to create a FUSE application, go back to browser. And click on “create yours first application”,  on following page. depend on your OSE version, click on Fuse cartridge, 


or you can type in following URL in define my own application









https://raw.github.com/jboss-fuse/fuse-openshift-cartridge/master/metadata/manifest.yml

In the next page, fill in your application name and domain name, 



After a few minutes of download and installing the FUSE application, you will be presented with the authorization information, please keep it. Remember the ID/PWD.


Go to the Fuse URL you will see the, logon using the ID/PWD and congratulation you have created the FUSE application.



And that's it, you can now start playing with Fuse on OpenShift Enterprise in your local environment.

Red Hat JBoss Fuse - Getting Started with Fuse Integration Service 2.0 Tech preview

I just realized that I did not do a getting started for Fuse Integration Service 2.0 Tech preview before I did the pipeline demo, thanks for those of you who reminded me! :)

To get started with FIS 2.0, for people who has just getting to know the technology, here is how I interpret it. Basically, it's divide into two aspect,

1. Integration development, FIS uses Apache Camel as the core technology that creates, orchestrate, compose microservices into a super lightweight thin integration layer, and become the API provider and service orchestrator through exposing RESTful or messaging service endpoints. And you can choose to either package and run it with Spring-Boot or Karaf.


2. Application Deployment and Management, FIS takes advantages of OpenShift platform, and allows you to separately deploy the micro-integration service among distributed environment, at the same time takes care of the failover, high availability, load balancing and service lookup problem for you.


So, now we know …

Red Hat JBoss Fuse/A-MQ - Fuse and A-MQ Version 6.3 GA is released!

Fuse and A-MQ 6.3 GA has just went out. Maybe, you would think this is just only a minor version release why should I care? Hold your thoughts on that! Because they have done a lot of improvements and also added many new features into this release.

Besides various bug fixes and making sure Fuse Fabric is much more stable. There are two major change in this version update:

New Tooling in JBoss Developer Studio (JBDS) 9.1 GA. Newer Apache Camel version – Camel v2.17. I was really impressed by the work put in to make developing Camel application much simpler. First is the installation of tooling itself. Now it has a all-in-one installer so you don't need to worry about which plugins you need to check. See the videos below to see the new "Getting Started" of Fuse 6.3.



And If you notice from the above video, the presentation of camel route in JBDS has also updated. It fixed some of the miss representation of logic and making it easier to read.

Old Camel Route
New Camel Route

Fuse Integration Service - Setup JBDS and create first quickstart application

Before we go and start creating our first application, I want to show you how to setup your JBoss Developer Studio, create a small application from the quickstart example and then running it on Fuse Integration Service.

I am using JBoss Developer Studio version 9, you can find it here.
After download the

jboss-devstudio-9.0.0.GA-installer-eap.jar
double-click it, and start installing with default values.

After successful installation, we will need install the plugins for Fuse, on JBoss Central view, select software update, select enable early access.


And select JBoss Fuse Development for the plugin,


Click on install, and we are all set to go!

First thing first, we want to create a Fuse project to deploy on the base of Fuse Integration Service, which is OpenShift. If you have not installed it, please go back to my previous post for instructions. So on your JBDS, right click and start creating the project. Select new, maven project, if you have installed the plugin correctly, you should …
