Prev Question Next Question

Question

How should the Kubernetes manifests be modified to allow Kubernetes environment integration with Cisco ACI?

Answers

A. The metadata section must contain the Cisco APIC management IP.

B. The manifest does not have to be changed, but the Kubernetes object is not discovered by Cisco ACI if this is not defined in the manifest.

C. The manifests must include ACI EPG reference.

D. No change is needed to perform this action.

To integrate a Kubernetes environment with Cisco ACI, the Kubernetes manifests must be modified to include ACI-specific information. The correct answer to the question is C. The manifests must include ACI EPG reference.

ACI (Application Centric Infrastructure) is a software-defined networking solution developed by Cisco that provides a policy-based approach to application deployment in data centers. ACI allows for the automation and orchestration of network and security policies to support the dynamic requirements of modern applications.

Kubernetes, on the other hand, is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. Kubernetes can be integrated with ACI to provide network automation and policy-based networking for containerized applications.

To integrate Kubernetes with ACI, the Kubernetes manifests must be modified to include ACI EPG (Endpoint Group) references. An EPG is a collection of endpoints that share common network and security policies in ACI. The EPG defines the communication policy for the endpoints it contains, including the allowed protocols, ports, and other parameters.

To include ACI EPG references in the Kubernetes manifests, the following steps are typically required:

Create an ACI EPG that represents the Kubernetes namespace in which the application is deployed.
Assign the EPG to the appropriate ACI VLAN.
Modify the Kubernetes manifests to include the EPG reference in the metadata section. The EPG reference typically includes the name of the EPG and the name of the ACI tenant.

Here is an example of how an ACI EPG reference can be included in a Kubernetes manifest:

yaml
apiVersion: v1 kind: Pod metadata:   name: nginx-pod   labels:     app: nginx   annotations:     "aci.fabric.cisco.com/epg": "myapp-epg/prod" spec:   containers:   - name: nginx     image: nginx     ports:     - containerPort: 80

In this example, the EPG reference is included in the annotations section of the metadata. The value of the annotation is set to the name of the EPG (myapp-epg) and the name of the ACI tenant (prod).

In summary, to integrate Kubernetes with Cisco ACI, the Kubernetes manifests must be modified to include ACI EPG references. This allows for the automation and orchestration of network and security policies for containerized applications in the data center.
