1) The artifact name built was helloworld.jar but the copy command was referring to different name hence build is failing: ``` Step 6/8 : COPY --from=BUILD /usr/src/app/target/app.jar /opt/app.jar lstat usr/src/app/target/app.jar: no such file or directory ``` Fixed by copying helloworld.jar instead of app.jar 2) Since the jar being deployed was a thin jar without dependencies, it was not able to find Spark classes and thus failing: ``` 2017-07-03T10:23:49.370518638Z Exception in thread "main" java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: spark/Request 2017-07-03T10:23:49.373134679Z at helloworld.Hello.main(Hello.java:7) 2017-07-03T10:23:49.373163432Z Caused by: java.lang.NoClassDefFoundError: spark/Request 2017-07-03T10:23:49.373167578Z ... 1 more 2017-07-03T10:23:49.373170484Z Caused by: java.lang.ClassNotFoundException: spark.Request 2017-07-03T10:23:49.373173097Z at java.net.URLClassLoader.findClass(URLClassLoader.java:381) 2017-07-03T10:23:49.373175661Z at java.lang.ClassLoader.loadClass(ClassLoader.java:424) 2017-07-03T10:23:49.373178321Z at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) 2017-07-03T10:23:49.373180932Z at java.lang.ClassLoader.loadClass(ClassLoader.java:357) 2017-07-03T10:23:49.373183512Z ... 1 more ``` Fixed by using the "-with-dependency" jar |

Draft: Streamlined Kubernetes Development
NOTE: Draft is experimental and does not have a stable release yet.
Draft makes it easy to build applications that run on Kubernetes. Draft targets the "inner loop" of a developer's workflow: as they hack on code, but before code is committed to version control.
Using Draft is as simple as:
draft createto containerize your application based on Draft packsdraft upto deploy your application to a Kubernetes dev sandbox, accessible via a public URL- Use a local editor to modify the application, with changes deployed to Kubernetes in seconds
Once the developer is happy with changes made via Draft, they commit and push to version control, after which a continuous integration (CI) system takes over. Draft builds upon Kubernetes Helm and the Kubernetes Chart format, making it easy to construct CI pipelines from Draft-enabled applications.
Here is a video demonstrating how to set up Draft on Azure Container Services:
