      volumes:
        - name: pinpoint-agent-1
          emptyDir: {}
      initContainers:
        - name: pinpoint-agent
          image: >-
            image-registry.openshift-image-registry.svc:5000/pinpoint-agent-test/pinpoint-agent@sha256:4d703d7471e98eb4d66c6e76dc1079d536d7fc746d1a1b6f11e23514c7afde6d

          volumeMounts:
            - name: pinpoint-agent-1
              mountPath: /deployments-pinpoint-agent

So let's define a emptyDir Type of volume pinpoint-agent-1,initcontainers When the container starts , Put this pinpoint-agent-1 Mount the volume to /sharedFiles/AppServerAgent Catalog , And put the container in the mirror layer /pinpoint-agent Copy the files in the directory to pinpoint-agent-1 Under the volume , then initContainers The mission of , The normal exit .

containers:
        - resources: {}
          readinessProbe:

tomcat The container will pod Of namespace As APP_NAME name , take pod Of name As AGENT_ID, adopt JAVA_OPTS Variable configuration client related parameters .

notes ： and initcontainers The container mounts the same pinpoint-agent-1 volume
