title: Kubernetes pod arguments are not displayed in Service under Args: without error
body: <p>I created a singlePod.yaml file to properly describe the kubernetes pod service that passes arguments, and can run like this:
  kubectl create -f ./singlePod.yaml</p>
  
  <p>I want the arguments called to match Docker:</p>
  
  <pre><code>docker run -it -p 8080:8080 joethecoder2/spring-boot-web cassandra_ip=127.0.0.1 cassandra_port=9042
  
  apiVersion: v1
  kind: Pod
  metadata:
    name: spring-boot-web-demo
    labels:
      purpose: demonstrate-spring-boot-web
  spec:
    containers:
    - name: spring-boot-web
      image: docker.io/joethecoder2/spring-boot-web
      env:
      - name: "cassandra_ip"
        value: "127.0.0.1"
      - name: "cassandra_port"
        value: "9042"
      command: ["java","-jar", "spring-boot-web-0.0.1-SNAPSHOT.jar", "cassandra_ip=127.0.0.1", "cassandra_port=9042"]
      args: ["$(cassandra_ip)", "$(cassandra_port)"]

  <p>The problem is that although the arguments have been added to the below service, the arguments do not take effect to the calling program (spring-boot-web-0.0.1-SNAPSHOT.jar)</p>

  <p>I am expecting the results from the calling java program:
  to use the cassandra_ip and cassandra_port </p>
  
  
  
  <p>The service, does not properly show the arguments being displayed by the service, and also the running java program inside docker, does not show that the arguments are called.</p>
