Bluemix - Deploying a Java Web Application
This document discusses deploying a Java web application to Bluemix using Cloud Foundry. It describes creating a simple JAX-RS web app, configuring a Maven build script and manifest, checking the code into a Git project on Jazz Hub, building and deploying the app through a Jenkins pipeline that runs the Maven and deployment scripts, and testing the deployed URL.

- 1. Deploying on Bluemix CloudFoundry / Java Web App craigtrim@gmail.com This is not an official IBM position. The views expressed are solely my own.
- 2. Create the WebApp • Simple JAX-RS Web app • Given a URL in this format • <host:port>/blog/rest/get?name=C raig • Return a result on the screen • The structure of the web app is explained here: • http://trimc- jee.blogspot.com/2015/01/an- introduction-to-java-api-for-restful.html
- 3. Configure a build script •It’s going to be easier if we put our Maven build configuration into a shell script that can be called during the CF deployment process • My script is simple: • mvn clean install • Remember to make your script executable • chmod +x <script> • Make sure the script works locally first
- 4.
- 5. Configure a deployment script •The ${CF_APP} env variable is passed in automatically • Specify the manifest we created on the prior slide
- 6. Check your codeinto the Jazz Hub • http://www.slideshare.net/CraigTrim/ibm -bluemix-creating-a-git-project • http://www.slideshare.net/CraigTrim/ibm -bluemix-building-a-project-with-maven
- 7. Build and Deploy •We’re only going to add one stage that combines both building and deploying
- 8. Input Configuration • Iprefer to invoke this deploy stage manually
- 9.
- 10. Configure the Deploy Job •Just invoke the two scripts we previously created • There is nothing to prevent us from doing deep scripting within this web window • But it’s easer to work with external files • It’s likely I’ll only have to configure this web dialog once
- 11.
- 12. Deploy: Not yetrun • Here’s my pipeline • Let’s go ahead and run the deployment and see what happens … • The stage can be manually invoked by clicking the arrow in the upper right
- 13. Deploy: Pending • Click“View logs and history”
- 14. Deploy: Running • Thisis a running log file; scroll down to view the input as the system invokes both Maven and (if the build is successful) proceeds to perform a Cloud Foundry deployment
