positive.code: 
  The deployer template parameter options and their defaults are listed above in the *_metrics.yaml_* file. If required, you can override these values when creating the *metrics deployer*.
  
  For example, access to the master server is configured by the `*MASTER_URL*`
  parameter. The default value is `https://kubernetes.default.svc:443`, however
  this likely needs to be overridden and configured for your environment. Failing
  to set this parameter properly may result in timeout errors in the deployer
  logs. You may also want to override the value for `*IMAGE_PREFIX*` to suit your
  deployment.
  
  However, the only required parameter is `*HAWKULAR_METRICS_HOSTNAME*`. This
  value is required when creating the deployer because it specifies the hostname
  for the Hawkular Metrics
  link:../architecture/core_concepts/routes.html[route]. You will need to know the
  value of `*HAWKULAR_METRICS_HOSTNAME*` when
  link:#accessing-metrics-in-the-console[configuring the console] for metrics
  access.
