Introduction of Cloud Foundry on SAP Cloud Platform enables a lot of possibilities to deploy various applications on the cloud. Jenkins is one of the most asked and some people may struggle to find a place to run it.

In this blog, I’ll show how to deploy Jenkins on Cloud Foundry environment on SAP Cloud Platform.

Download Jenkins.war

Go to https://jenkins.io/download/ and download Generic Java Package (war) of the version you prefer.

Deploy Jenkins on Cloud Foundry

Connect to Cloud Foundry using CLI. (See how to download here).

cf api https://api.cf.eu10.hana.ondemand.com
cf login

We’re going to deploy Jenkins.war using this special buildpack.

cf push <path_to_jenkins.war> -b https://github.com/Altoros/jenkins-buildpack -m 2G <unique_app_name>

Here is what it looks like for me:
