Cloud Foundry – Push Application into Space

As we have already created sample greet application in previous post Cloud Foundry – Create First Application, we will see how we can push the same application into Cloud Foundry development space. As we have already seen, there is a PUSH command in Cloud Foundry Commands. We need to use the same command to push our application into Cloud Foundry. Prior to that, we need to login into the Cloud Foundry CLI by using LOGIN command. If you have any issues with login into the Cloud Foundry by using CF-CLI, look into previous post which I have already explained. The below are the steps which require to follow to push our application into Cloud Foundry,

Open CF-CLI and navigate into the application target directory, target directory will be created automatically as on when we issue mvn clean install command on project.

Now, we can issue the below command to deploy application jar file into Cloud Foundry.

cf push cfgreet -p CFGreet-0.0.1-SNAPSHOT.jar

cf push is the command used for pushing the application
cfgreet is my application name
-p is the path specifying
CFGreet-0.0.1-SNAPSHOT.jar is the actual CFGreet application which we are trying to deploy into cloud foundry.

Now, we check from Pivotal account from UI and check CFGreet application is present or not in development space.

My CFGreet app is present in development space with the Route of https://cfgreet.cfapps.io. Let’s access our API along with this route, https://cfgreet.cfapps.io/greet/javaisocean the output will be look like Hello javaisocean… Welcome to Cloud Foundry 🙂

Now, your application Successfully pushed into Cloud Foundry and running.
