Introduction

Once you have runtime environment setup on-premise, you want to be able to deploy & undeploy mule apps. Let’s find out how easily can this be done and appreciate the beauty behind its simplicity.

Environment

Environment used was as following

• JRE or JDK 1.8
• Mule 3.8 runtime
• Runtime Manager Agent

Source Code

You can find the source code of this project from here

Export app

Mule Developer is supposed to give the app packaged in a deployable archive to Mule Administrator. Mule Developer can do this straight from Anypoint studio.

Start mule specifying placeholder value

This project is based off from the environment aware project template. Therefore, you will need to pass expected placeholder value when running mule runtime.

There are vairous ways to do so, but the simplest would be passing as a parameter when running mule from a command line.

C:\mule\onprem_servers\max\bin>mule -M-Dmule.env=Development

Make sure the placeholder value was fed as expected

Deploy app

The deployable archive has everything necessary from within. Thus, app deployment is as easy as putting this into apps folder of mule runtime.

Once the deployment is successful, you will see the deployable archive file was consumed and created an anchor file.

{YourAppName}-anchor.txt

Undeploy app

Undeploying the app is done by removing the anchor file created after deployment above. Let’s see how it’s done.

Summary

You have now seen how easy it is to deploy and undeploy app from customer-hosted runtime. I reckon the beauty behind this simplicity is remarkable. There is no mess around with setup file, touching windows registry, deploying artifacts into dependent proprietary database, etc. All it takes is creating a self-contained zip file and it has everything necessary to run the app within. It is simple, light-weight, independent and manageable. I hope everyone see the beauty.
