How to achieve high availability on Openshift ?

Hi,

High availability is a very important feature for any kind of infrastructure. As the name suggests the services should be available at any given point of time. You can have several parallel instance of an application and can scale up and down depending on the business requirement, without worrying much about the cost. Load is distributed across different servers, and even if one or more of the servers fails, the application is still accessible via the other application instances. HA is crucial for scalable enterprise applications, as you can improve performance by adding more gears (which will be replica of your current one).

Lets create a scaled application and see how High Availability works in Openshift. Follow Below steps :

Step-1: Create a new application. Please note that we are using “-s” here to enable scaling:

$ rhc app create -a myhaproxy -t jbossas-7 -s

Above will create a directory “myhaproxy” at the location from where you ran the command from your terminal.

Now there are two types of scaling : Automatic and Manual. The command mentioned in Step-1 creates an application which is auto-scalable, i.e. the application will be scaled based on the incoming load. However you can also scale your application manually. For eg: if you are anticipating a certain amount of load, or you have limited resources (less number of gears available), or if you want to control the cost manually.

Lets see how can we scale our application manually.

Step-2 : Navigate from the directory “myhaproxy” which got created in Step-1 to :

$ cd myhaproxy/.openshift/markers/

Step-3 : Create a blank file as “disable_auto_scaling” :

$ touch disable_auto_scaling

Step-4 : Now add the changes to git repository, commit the changes and push them to Openshift server :

..

$ cd ../../

$ git add .openshift/markers/disable_auto_scaling

$ git commit -m "disabling auto-scaling"

$ git push

..

Step-3 : Once the auto-scaling is disabled, lets enable manual scaling :

Create an SSH connection to your application :

$ssh UUID@APPNAME-NAMESPACE.rhcloud.com

for eg :

ssh 123a456c09d12345b123a12345cc1234@myhaproxy-mydomain.rhcloud.com

Step-4 : Run below command to enable manual scaling :

$ add gear -a APPNAME -u UUID -n NAMESPACE

for eg :

..

add-gear -a myhaproxy -u 123a456c09d12345b123a12345cc1234 -n mydomain

..

Now manual scaling is enabled. Let’s check if High Availability works. Try to access the application using the url :

myhaproxy-mydomain.rhcloud.com, this gives the welcome page.

Now again ssh to your application using :

ssh 123a456c09d12345b123a12345cc1234@myhaproxy-mydomain.rhcloud.com

Grep for the java process and kill the process id, now our JBoss server is down. If high availability is working, the url should still work.

myhaproxy-mydomain.rhcloud.com, if this gives the welcome page, we are good :). (Preferably try from a different browser)

You can see high availability statistics from the management console, by logging in to

You can also select minimum or maximum number of gears you want to scale up to.

Curl Based Management & Monitoring in JBossAS7 with HTTP-JSON APIs

Trust me None other Application Server provides this kind of amazing feature, except JBossAS7. JBoss AS7 is one of the bestest application available in the Middleware World, As it provides much more facilities to the Administrators in order to manage/configure and monitor various resources. As we are already familier with a utility called as “$JBOSS_HOME/bin/jboss-cli.sh” is one of the most powerful and easiest utility which can be used to manage and monitor JBossAS7.

In this demonstration we will see that JBoss AS7 provides another best feature, which allows us to easily access & monitor & management the JBoss AS7 using OS level utilities like “curl”. Yes, JBoss AS7 provides HTTP-JSON based APIs which can be used to achieve the same. So lets see some of it’s features…

So lets start JBossAS7 like following:

    ./standalone.sh -c standalone-full.xml 

NOTE: In all the following operations we will assume that you have created a ManagementRealm User with username “admin” and password as “admin123” (you can create any user name/password based on your requirement), Then change the username & password in the mentioned demo URLs like “http://admin:admin123@localhost:9990/management/”

NOTE: Curl is a free utility for non-interactive download of files from the Web.

So Open a Terminal (command prompt) and start testing the following Curl command on your JBossAS7

Managing JBossAS7 with HTTP-JSON APIs using wget

Hi,

JBoss AS7 is one of the bestest application available in the Middleware World, As it provides much more facilities to the Administrators in order to manage/configure and monitor various resources. As we are already familier with a utility called as “$JBOSS_HOME/bin/jboss-cli.sh” is one of the most powerful and easiest utility which can be used to manage and monitor JBossAS7.

In this demonstration we will see that JBoss AS7 provides another best feature, which allows us to easily access & monitor the JBoss AS7 using OS level utilities like “curl” or “wget”. Yes, JBoss AS7 provides HTTP-JSON based APIs which can be used to achieve the same. So lets see some of it’s features…

So lets start JBossAS7 like following:

    ./standalone.sh -c standalone-full.xml 

NOTE: In all the following operations we will assume that you have created a ManagementRealm User with username “admin” and password as “admin123” (you can create any user name/password based on your requirement), Then change the username & password in the mentioned demo URLs like “http://admin:admin123@localhost:9990/management/

NOTE: Wget is a free utility for non-interactive download of files from the Web. It supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.
Wget can follow links in HTML pages and create local versions of remote web sites, fully recreating the directory structure of the original site. This is sometimes referred to as “recursive downloading.” While doing that, Wget respects the Robot Exclusion Standard (/robots.txt). Wget can be instructed to convert the links in downloaded HTML files to the local files for offline viewing.
More informations about “wget” utility can be found in the following link: http://en.wikipedia.org/wiki/Wget

Accessing Deployment Details

wget -O out.txt "http://admin:admin123@localhost:9990/management/deployment/TestLogging.ear/subdeployment/Log4jDemoOne.war?operation=resource&include-runtime&recursive&json.pretty"

Suppose you have deployed an EAP application with name “TestLogging.ear” which contains a sunmodule with name “Log4jDemoOne.war” then you can get it’s runtime information using the above command, the outputwill be something like following:


{"subsystem" : {"web" : {
    "active-sessions" : 0,
    "context-root" : "/Log4jDemoOne",
    "duplicated-session-ids" : 0,
