Setting up service graph

Software requirements

You can configure the Kubernetes cluster with various deployment topologies and the following table provides the topologies that are supported in service graph:

To complete setting up service graph in Citrix ADM, click the topology type that you have configured for your Kubernetes cluster and complete the mentioned procedures:

• Single-tier or Unified ingress topology

• Dual-tier or Service Mesh Lite topology

• Service mesh topology

Note

The procedure to set up service graph for dual-tier and service mesh lite topologies remains the same.

Single tier or Unified ingress topology

Ensure that you complete the following steps to set up the single tier or unified ingress topology. For more information, see Detailed procedures to setup single tier or unified ingress topology.

• Configured Kubernetes cluster with single tier or unified ingress topology.

• Added VPX, MPX, SDX, BLX instance in Citrix ADM and enabled Web Insight.

• Added Kubernetes cluster in Citrix ADM.

Dual tier or Service Mesh Lite topology

Ensure that you complete the following steps to set up the dual tier or service mesh lite topology. For more information, see Detailed procedures to setup dual tier or service mesh lite topology.

• Configured Kubernetes cluster with any one of the supported topologies.

• Installed a Citrix ADM agent and configured to enable communication between Citrix ADM and Kubernetes cluster or managed instances in your data center or cloud.

  You can also deploy a Citrix ADM agent as a microservice. For more information, see the Install Citrix ADM Agent section in Getting Started.

• Configured Static routes on Citrix ADM agent to enable communication between Citrix ADM and Citrix ADC CPX.

  Note

  You can ignore this procedure if you have deployed Citrix ADM agent as a microservice in the same cluster.

• Downloaded the sample deployment files from GitHub repository.

• Added required parameters in CPX YAML file to ensure successful CPX registration with Citrix ADM.

• Added a VPX, MPX, SDX, or BLX instance in Citrix ADM.

• Added the Kubernetes cluster in Citrix ADM.

• Deployed a sample microservice application.

• Deployed Citrix ADC CPX and registered CPX to Citrix ADM (applicable only for two-tier architecture).

• Enabled Auto-select Virtual Servers to license the CPX virtual servers.

• Enabled Web transaction and TCP transaction settings to All for Citrix ADM agent to get HTTP and TCP transactions.

• Sent traffic to microservices.

Service mesh topology

Ensure that you complete the following steps to set up the service mesh topology. For more information, see Detailed procedures to setup service mesh topology.

• Configured Kubernetes cluster version 1.14.0 with any one of the following service mesh topologies:

  • Citrix ADC CPX as a sidecar proxy for Istio

  • Citrix ADC as an Ingress Gateway for Istio

  For more information, see Citrix ADC Istio Adapter deployment architecture

• Enabled admissionregistration.k8s.io/v1beta1 API. You can verify the API by using:

  kubectl api-versions | grep admissionregistration.k8s.io/v1beta1

  The following output indicates that the API is enabled:

  admissionregistration.k8s.io/v1beta1

• Installed Istio istio v.1.3.0.

• Installed Helm version 3.x.

• Installed a Citrix ADM agent and configured to enable communication between Citrix ADM and Kubernetes cluster or managed instances in your data center or cloud.

  You can also deploy a Citrix ADM agent as a microservice. For more information, see the Install Citrix ADM Agent section in Getting Started.

• Configured Static routes on Citrix ADM agent to enable communication between Citrix ADM and Citrix ADC CPX.

  Note

  You can ignore this procedure if you have deployed Citrix ADM agent as a microservice in the same cluster.

• Configured the required parameters to populate the service mesh topology data.

• Deployed a sample application.

• Added the Kubernetes cluster in Citrix ADM.

• Enabled Auto-select Virtual Servers to license the virtual servers.

• Enabled Web transaction and TCP transaction settings to All for Citrix ADM agent to get HTTP and TCP transactions.

• Sent traffic to microservices.

After you complete the required setup procedures, you can view service graph populated at Applications > Service Graph and in the Microservices tab. For more information, see Service Graph details.
