What

For SRE or a customer to manage Camel K, they need a visual representation of the metrics, specifically the SLIs.

How

The dashboard is a GrafanaDashboard resource. This will be the same as the creation and reconciliation of other child resources created as part of a IntegrationPlatform CR instantiation, for example, the deployment resource.

Futher Information:

• Create/Update service SLO dashboard

Note:

• This could be feature flagged in the CR spec and only created if turned on
• The grafana operator needs to be installed on cluster for the GrafanaDashboard CR kind to exist. It is easy to check for the existence of a resource kind using the following code

  import (
  	"github.com/operator-framework/operator-sdk/pkg/k8sutil"
  	"k8s.io/client-go/discovery"
  	"k8s.io/client-go/rest"
  )
  
  ...
  
  // hasServiceMonitor checks if ServiceMonitor is registered in the cluster.
  func hasServiceMonitor(config *rest.Config) (bool, error) {
  	dc := discovery.NewDiscoveryClientForConfigOrDie(config)
  	apiVersion := "integreatly.org/v1alpha1"
  	kind := "GrafanaDashboard"
  
  	return k8sutil.ResourceExists(dc, apiVersion, kind)
  }
