6 years ago @bacongobbler see bash scripts that work just fine for the example-spring-boot project.
1.) Aside from the .JAR file binding problem, that you had in the example, I was able to fix it for this example. 2.) It appears that the problem was with port forwarding, and it wasn't enabled properly. 3.) It appears that name collisions of the image name uploaded to docker hub were causing connectivity problems with the port numbers as well, and there were strange error messages, which necessitated me to change the name in the draft.toml file to example-javahello , which was kind of a pain.
As it turns out the helm package manager has a bug in it, which won't allow you to add a package to helm ls, therefore it has to be ignored, and the package image has to be added using kubectl run command, in addition I implemented port forwarding which was needed in order to allow access to the external port, since the internal port isn't the correct one.
The problem was that the Dockerfile and draft up and draft connect script did not work for the spring boot example.
