Step 10: Auto-update the running application
Build System Demo
Suppose we've been working on the sample app. Let's increment the version and trigger a new build.
Edit the plan.sh file in your forked GitHub repo (as we did earlier) by clicking the pencil icon.
Change the value of pkg_version from 1.0.1 to 1.0.2, then use the Commit changes button to update the master branch.
Chef Habitat Builder will detect the change and start a new build automatically. You can view the resulting output in the Chef Habitat Builder web app. Once the build job completes, re-run the docker commands to verify the updated container:

With the container runnning, visit http://localhost:8000/and see the new version of the sample app.
