Example YAML

Below is an example RKE template configuration file for reference.

The YAML in the RKE template uses the same customization that is used when you create an RKE cluster. However, since the YAML is within the context of a Rancher provisioned RKE cluster, the customization from the RKE docs needs to be nested under the rancher_kubernetes_engine directive.

  6. enable_cluster_alerting: false
  7. # This setting is not enforced. Clusters
  8. # created with this sample template
  9. # would have alerting turned off by default,
  10. # but end users could still turn alerting
  11. # on or off.
  13. enable_cluster_monitoring: true 
  14. # This setting is not enforced. Clusters
  15. # created with this sample template
