   |`*IMAGE_PREFIX*`
   |Specify prefix for metrics components. For example, for *openshift/origin-metrics-deployer:latest*, set prefix to *openshift/origin-*.
  +
  +|`*MODE*`
  +|Can be set to: *preflight* to perform validation before a deployment; *deploy* to perform an initial deployment; *refresh* to delete and redeploy all components but to keep persisted data and routes; *redeploy* to delete and redeploy everything (losing all data in the process); *validate* to re-run validations after a deployment.
  +
  +|`*IGNORE_PREFLIGHT*`
  +|Can be set to *true* to disable the preflight checks. This will allow the deployer to continue even if the preflight check has failed.
  +
  +|`*USER_WRITE_ACCESS*`
  +|If user accounts should be able to write metrics. Defaults to 'false' so that only Heapster can write metrics and not individual users. It is recommended to disable user write access, if enabled any user will be able to write metrics to the system which can affect performance and can cause Cassandra disk usage to unpredictably increase.
