In this step you will deploy the app to Swisscom Application Cloud.

Before we can push it, we need to compile the app using Leiningen. To do so, run

$ lein uberjar

...

Created /.../cf-sample-app-clojure/target/cf-sample-app-clojure-0.1.0-SNAPSHOT-standalone.jar

Push your app to the cloud by executing the following command and replacing the “my-random-hostname” with your own hostname. This will be part of the URL your app will be reached at and it has to be globally unique so be creative.

The -b java_buildpack tells Cloud Foundry to use the Java buildpack for our app and the -p target/cf-sample-app-clojure-0.1.0-SNAPSHOT-standalone.jar tells Cloud Foundry where to find the compiled application to push to the Cloud.

$ cf push my-clojure-app -b java_buildpack -p target/cf-sample-app-clojure-0.1.0-SNAPSHOT-standalone.jar -n my-random-hostname
