By
now we have the funtest domain available in OpenShift. The next step is to
create a sample custom application ,deploy that to the fundomain and access the
application online.
Create
a application "funtest" with Jboss 7. The application will deploy to
the JBoss 7 Container
[root@vx111a funtest]# rhc app create -a funtest -t jbossas-7
Application Options

Creating application 'funtest' ... done

Warning: Permanently added the RSA host key for IP address
'50.16.11.24' to the list of known hosts.
Your application 'funtest' is now available.
URL: http://funtest-fundomain.rhcloud.com/
SSH to:
537f2c545973caec750002b8@funtest-fundomain.rhcloud.com
Git remote:
ssh://537f2c545973caec750002b8@funtest- fundomain.rhcloud.com/~/git/funtest.git/
Cloned to: /soa/openShift/funtest/funtest
Run 'rhc show-app funtest' for more details about your app.
So
when we create the application using the above command , we can see a directory
created at the current directory from where we ran the command.
The
directory will be with the name of the application, funtest in this case. When you
check the directory structure we can see a deployments directory , conf
directory and pom.xml file.
Since
this was a custom application, we dont need pom.xml file. remove the pom.xml
file. For the demo purpose ,i have written a Sample web application by the name
"sample-app.war"
Now
copy the war file to the deployments directory. Once the copy is done we need
to create a file called "applicationName.dodeploy" for telling the
OpenShift to deploy the applicaiton.
touch Sample-app.war.dodeploy
The
next thing to do is to copy the deployments to the OpenShift online account. For
that we can use the rsync command provided
by linux. run the below command
[root@vx111a funtest]# rsync -avz /soa/openShift/funtest/funtest/deployments/
537f2c545973caec750002b8@funtest-fundomain.rhcloud.com:/var/lib/openshift/537f2c545973caec750002b8/app-deployments/2014-05-23_07-09-16.841/repo/deployments
sending incremental file list
./
.gitkeep
Sample-app.war
Sample-app.war.dodeploy
sent 1828 bytes received
72 bytes 165.22 bytes/sec
total size is 2514
speedup is 1.32
There
are few things that we need to , for copying the files we need to know the
location where to copy the files. We get the below details when creating an
application
URL:
http://funtest-fundomain.rhcloud.com/
SSH to:
537f2c545973caec750002b8@funtest-fundomain.rhcloud.com
Git remote: ssh://537f2c545973caec750002b8@funtest- fundomain.rhcloud.com/~/git/funtest.git/
Cloned to:
/soa/openShift/funtest/funtest
for
using the rsync command we need to use the Git
Remote location given above.In the rsync command
/soa/openShift/funtest/funtest/deployments/ : the location in our
local machine from where the war file is available
537f2c545973caec750002b8@funtest-fundomain.rhcloud.com : the OpenShift
location where we need to copy the deployments
/var/lib/openshift/537f2c545973caec750002b8/app-deployments/2014-05-23_07-09-16.841/repo/deployments
: the
location on OpenShift where we need to deploy the applications
So
for finding the location where we need to push the deployments ,we can get that
by Connecting to the SSH location using , run the below command
ssh 537f2c545973caec750002b8@funtest-fundomain.rhcloud.com

Now
we will login to the remote OpenShift machine. We can see the directories
available in the remote Machine.
Once
the rsync command is completed ,we ca n go to this location and see that our
deployments are copied.
/app-deployments/2014-05-23_07-09-16.841/repo/deployments
But
some how even after deploying the application to this location , we cant access
the application here. We need to copy the deployment war file to the /jboss/standalone/deployments/.
[funtest-fundomain.rhcloud.com deployments]\> ls
ROOT.war
ROOT.war.deployed
Sample-app.war
Sample-app.war.deployed
So
the deployment is done, we can check the log files using
[funtest-fundomain.rhcloud.com 537f2c545973caec750002b8]\>

We
can access the application using,

are the Screen Shots,
More
to come , Happy Learning
