Deploying microprofile-conference demo microservice-vote service into a kube environment

[Scott Stark]

I'm looking at deploying the microprofile-conference demo app into a minikube type environment, and when I attempt to deploy the microservice-vote.jar executable jar as a docker image that run an executable jar I'm getting the following error on startup of the image:

[microservice-vote 754]$ oc logs microservice-vote-2584106616-wxn54

Starting the Java application using /opt/run-java/run-java.sh ...

Is there  a configuration of the liberty-maven-plugin or a property to specify on the command line to point to a previously extracted directory of the wlp server contents?

I'm not sure why the extraction path contains a '?' character, but I suspect that is what is causing the problem here, but I have not been able to get into the pod to inspect the /deployments directory.

not sure, but could it be that that question mark is originally some UTF-8 character and your container only supports ASCII? Just an idea :-)

Hi Scott,

I have not seen the problem you are seeing. https://github.com/WASdev/ci.docker.tutorials/tree/master/app might have useful info to help you along. If not, can you list which command did you use?

Thanks

Scott,

Further to my previous comments, https://github.com/WASdev/sample.microservicebuilder.docs/blob/master/dev_test_local_minikube.md has a better instruction to deploy the customised conference app to minikube, which should closely match what you are trying to do.
