I am trying to call specific java class, which contain main methods, using Kubernetes. However, every combination of command/args in my deployment yaml ends with an error when creating the container.

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: reports
spec:
  replicas: 1
  selector:
    matchLabels:
      app: reports
  template:
    metadata:
      labels: 
        app: reports
    spec:
      containers:
      - name: reports
        command: ["java -cp reports.jar com.gswsa.is.reports.TestRunner"]
        image: blah/reports:latest
        volumeMounts:
        - mountPath: /tmp/logs/reports
          name: logvolume

Dockerfile

FROM openjdk:8-jdk-alpine
RUN apk add --no-cache tzdata
RUN apk --update add fontconfig ttf-dejavu
ENV TZ America/New_York
VOLUME /tmp/logs/reports
ARG JAR_FILE=target/reports-1.0.0.jar
COPY ${JAR_FILE} /reports.jar
#ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/reports.jar"]
#CMD ["/usr/bin/java", "-jar", "-Dspring.profiles.active=PROD", "/reports.jar"]

I expect to be able to create multiple deployment scripts and call them whenever I would like with their specific arguments. If there is a better way, I am all ears! Thanks
