anchor.diff:  ==== Transport layer
   
   You can secure communication between nodes in the cluster with TLS on the Transport layer of Elasticsearch.
  -Configuring TLS for the Transport layer requires `xPackPlugins` be set to `Yes`.
  +Configuring TLS for the Transport layer requires `xPackPlugins` be set to `Yes` for 5.x versions, 
  +6.x versions less than 6.8.0 and 7.x versions less than 7.1.0. With `xPackPlugins` set to `Yes`, a trial
  +license will be applied to the cluster, which allows TLS to be configured on these versions.

   The following parameters can be used
   
   `esTransportCaCertBlob`::

  === Elastic Stack features (formerly X-Pack)
  
  A trial license for the Platinum features of the Elastic Stack can be deployed for
  Elasticsearch, and Kibana if also deployed, using the following parameter
  
  `xPackPlugins`::
  Select `Yes` to install a trial license of the platinum features. A trial license
  provides access to platinum features for 30 days. a value of `No`
  +
  . for Elasticsearch and Kibana 6.3.0+ will deploy with a free perpetual license
  providing access to the basic features. These versions use a distribution with
  Elastic Stack features included in the installation, and the license applied determines which
  features are activated.
  . for Elasticsearch and Kibana prior to 6.3.0, the X-Pack plugin will not be
  
negative.code: do this when deploying only Kibana, to secure internal traffic
  between Kibana and Elasticsearch through the internal load balancer.
  
  Configuring TLS for the HTTP layer requires `xPackPlugins` be set to `Yes` for 5.x versions, 
  6.x versions less than 6.8.0 and 7.x versions less than 7.1.0. With `xPackPlugins` set to `Yes`, a trial
  license will be applied to the cluster, which allows TLS to be configured on these versions.
  
  The following parameters can be used
  
  `esHttpCertBlob`::
  A base 64 encoded string of the PKCS#12 archive containing the certificate and key with which to secure the HTTP layer. This certificate will be used by all nodes within the cluster.
