Resources

CAP Operator Manager uses resource CAPOperator to install the CAP Operator. The CAPOperator resource has the following attributes -

• dnsTarget string - Public ingress URL for the cluster Load Balancer
• subDomain string - Subdomain of the CAP Operator subscription Server
• ingressGatewayLabels - Labels used to identify the istio ingress-gateway component and its corresponding namespace. Usually {“app”:“istio-ingressgateway”,“istio”:“ingressgateway”}

The below example shows a fully configured CAPOperator resource:

apiVersion: operator.sme.sap.com/v1alpha1
kind: CAPOperator
metadata:
  name: cap-operator
spec:
  subscriptionServer:
    subDomain: cap-op
  ingressGatewayLabels:
    - name: istio
      value: ingressgateway
    - name: app
      value: istio-ingressgateway

Here, we will automatically determine the cluster shoot domain and install the CAP Operator by setting the subscription server domain and the DNS Target. The DNS target is derived using the ingressGatewayLabels. For the above example, if the determined the cluster shoot domain is test.stage.kyma.ondemand.com, then the domain will be set as cap-op.test.stage.kyma.ondemand.com by default.

Note: The length of the domain should be less than 64 characters. Depending up on your cluster shoot domain, please choose a length appropriate subdomain.

The user can also maintain the DNS Target manually. In such cases, we will take over the value as it is. The user can maintain the DNS Target as shown below:

apiVersion: operator.sme.sap.com/v1alpha1
kind: CAPOperator
metadata:
  name: cap-operator
spec:
  subscriptionServer:
    subDomain: cap-op
  dnsTarget: public-ingress-custom.test.stage.kyma.ondemand.com
