Draft Up can not ADD jar dependency failed from Dockerfile

[quantum-fusion]

These are the steps that I am using to test DRAFT.

%git clone https://github.com/quantum-fusion/springboot_swagger_example-master-cassandra

%mvn clean install -DskipTests

%draft create

%draft up

Results Fail: draft up Draft Up Started: 'springboot_swagger_example-master-cassandra': 01CE78545ZSNAVCWTZGSYX69RJ springboot_swagger_example-master-cassandra: Building Docker Image: FAIL ❌ (7.0014s) Inspect the logs with draft logs 01CE78545ZSNAVCWTZGSYX69RJ

Question: I added a symbolic link for the Dockerfile.lrwxr-xr-x 1 me staff 24 May 23 15:36 Dockerfile -> ./dockerbuild/Dockerfile

Errata question: Is there something wrong with DRAFT that doesn't either see the symbolic link, or some other reason that DRAFT isn't seeing the Dockerfile when I use the draft up command?

@squillace @bacongobbler @radu-matei This was the stock java example.

This was the transcript: minikube start helm init cd $HOME/draft/examples/example-spring-boot draft create draft up Draft Up Started: 'example-spring-boot': 01CESC1PTH7BPVD46TWC2H341R example-spring-boot: Building Docker Image: SUCCESS ⚓ (115.0699s) example-spring-boot: Pushing Docker Image: SUCCESS ⚓ (44.5014s) example-spring-boot: Releasing Application: SUCCESS ⚓ (2.3197s) Inspect the logs with draft logs 01CESC1PTH7BPVD46TWC2H341R

draft connect Error: cannot get pod with buildID 01CESC1PTH7BPVD46TWC2H341R: timed out

[quantum-fusion]

@squillace @radu-matei This is draft connect issue is just like #776 for python, except this is for the java spring boot example.

[bacongobbler]

it looks like a recent change to the java pack fixed example-java, but broke example-spring-boot: https://github.com/Azure/draft/pull/749

Sorry that you hit this. For the time being, I'd suggest using another example app instead like example-java. I'll make a PR to remove the spring boot app for now until we have a better solution in place.

related: #727

[squillace]

No, it is not. The resolution for that one, as I read it, is that you did not have enough resources in minikube to run the application, so the pod did not get scheduled. While you didn't realize you didn't have enough, the python app worked properly when you freed up resources.

this one is just a bug in the container call. Per https://github.com/Azure/draft/issues/777#issuecomment-393323382, just now.

[squillace]

I'm THRILLED, however, that we are finding the bugs so that we can fix them.

[quantum-fusion]

@squillace @bacongobbler I am glad to help, and you have the proper accounting and score now. Squillace is right, the python example was out of resources, the java spring boot bug is different, but bacon gobbler is on top of it now.

@squillace @bacongobbler I was so thrilled to get my Microsoft Developer tour coffee cup, and I have the video footage of the draft example, and the showcase of kubernetes with minecraft. I haven't been able to resurrect that demo yet from developer conference, but figured we can stew on these example test cases for starters. I know there is a GitHub repo out there too from developer tour that we had in DC.

[squillace]

Where did you catch the tour? whoops: DC. do you remember who did the demos?

[quantum-fusion]

@squillace The Developer tour was here in Washington, DC.

@squillace @bacongobbler

This testcase was executed draft/examples/example-java

Therefore the results are a success for /example/example-java

Conclusion: I recommend that you put a bug fix into draft/examples/example-spring-boot to fix the Dockerfile and bindings for that test case.

[bacongobbler]

We're removing the spring boot app for the time being, since we just need one example java app for demonstration purposes. Thank you SO much for the feedback!

@berndverst @ruthieyakubu @squillace See the Developer tour DC lineup, and links.

[berndverst]

Just FYI

@quantum-fusion The Minecraft demo during our first developer tour was a deployment using Helm and just using Kubernetes directly. (It was being deployed to AKS) https://github.com/kubernetes/charts/tree/master/stable/minecraft

When I demo'd draft I deployed a Python Flask application. I of course know that Draft Pack inside out, so I know my app is being started with app.py which must spawn a HTTP server. For something more real world you'd definitely want to provide your own Draft pack. Never tried the Java Draft packs myself.

Please also note that Draft has changed quite a bit since the DC Dev Tour event.
