Feature Description

The AMF is built on the Kubernetes cluster strategy, which implies that it has adopted the native concepts of containerization, high availability, scalability, modularity, and ease of deployment. To achieve the benefits offered by Kubernetes, AMF uses the construct that includes the components such as pods and services.

Depending on your deployment environment, the AMF deploys the pods on the virtual machines that you have configured. Pods operate through the services that are responsible for the intrapod communications. If the machine hosting the pods fail or experiences network disruption, the pods are terminated or deleted. However, this situation is transient and AMF spins new pods to replace the invalid pods.

The following workflow provides a high-level visibility into the host machines, and the associated pods and services. It also represents how the pods interact with each other. The representation might defer based on your deployment infrastructure.

Note

Currently, LI endpoint is not supported.

Pods

A pod is a process that runs on your Kubernetes cluster. Pod encapsulates a granular unit known as a container. A pod contains one or multiple containers.

Kubernetes deploys one or multiple pods on a single or multiple nodes which can be a physical or virtual machine. Each pod has a discrete identity with an internal IP address and port space. However, the containers within a pod can share the storage and network resources.

The following tables list the AMF pod names and the Kubernetes node names on which they are deployed depending on the labels that you assign. For information on how to assign the labels, see Associating Pods to the Nodes.

Note

Maximum number of pods that can be configured per node is 256.

Note

In case of separate CDL deployment, CDL pods are visible under CDL namespace.

Services

The AMF configuration is composed of several microservices that run on a set of discrete pods. Microservices are deployed during the AMF deployment. AMF uses these services to enable communication between the pods. When interacting with another pod, the service identifies the pod's IP address to initiate the transaction and acts as an endpoint for the pod.

The following table describes the AMF services and the pod on which they run.

Note

In case of separate CDL deployment, CDL related services are visible under CDL namespace.

Open Ports and Services

The AMF uses different ports for communication. The following table describes the default open ports and the associated services.

Table 5. Open Ports and Services
Port	Service	Usage
22	SSH	SMI uses TCP port to communicate with the virtual machines.
80	HTTP	SMI uses TCP port for providing Web access to CLI, Documentation, and TAC.
443	SSL/HTTP	SMI uses TCP port for providing Web access to CLI, Documentation, and TAC.
6443	HTTP	SMI uses port to communicate with the Kubernetes API server.
9100	jetdirect	SMI uses TCP port to communicate with the Node Exporter. Node Exporter is a Prometheus exporter for hardware and OS metrics with pluggable metric collectors. It allows you to measure various machine resources, such as memory, disk, and CPU utilization.
10250	SSL/HTTP	SMI uses TCP port to communicate with Kubelet. Kubelet is the lowest level component in Kubernetes. It is responsible for what is running on an individual machine. It is a process watcher or supervisor focused on active container. It ensures the specified containers are up and running.
10251	SSL/HTTP	SMI uses TCP port to interact with the Kube scheduler. Kube scheduler is the default scheduler for Kubernetes and runs as part of the control plane. A scheduler watches for newly created pods that have no node assigned. For every pod that the scheduler discovers, the scheduler becomes responsible for finding the best node for that pod to run on.
10252	apollo-relay	SMI uses this TCP port to interact with the Kube controller. The Kubernetes controller manager is a daemon that embeds the core control loops shipped with Kubernetes. The controller is a control loop that watches the shared state of the cluster through the API server and makes changes to move the current state to the desired state.
10256	HTTP	SMI uses TCP port to interact with the Kube proxy. Kube proxy is a network proxy that runs on each node in your cluster. Kube proxy maintains network rules on nodes. These network rules allow network communication to your pods from network sessions inside or outside of your cluster.
2024	SSH	AMF Ops Center uses this port to provide the ConfD CLI access.
9090	HTTP	AMF REST endpoint pods use this port to expose the APIs to support NRF interface specific CLIs.
8090	HTTP	AMF REST endpoint pods use this port for routing incoming SBI messages to REST-EP pods.
8890	gRPC/HTTP	AMF REST endpoint pods use this port to receive timer notification from CDL.
3179	Tcpwrapped	SMI uses this TCP port for Calico(Kubernetes networking). Calico is used for routing the networking packets to pods.

In addition to the preceding ports, AMF uses the ports that are destined for SMI for routing information between hosts. For more information on SMI ports, see Ultra Cloud Core Subscriber Microservices Infrastructure Operations Guide.

Associating Pods to the Nodes

This section describes how to associate a pod to the node based on their labels.

After you have configured a cluster, you can associate pods to the nodes through labels. This association enables the pods to get deployed on the appropriate node based on the key-value pair.

Labels are required for the pods to identify the nodes where they must get deployed and to run the services. For example, when you configure the protocol-layer label with the required key-value pair, the pods are deployed on the nodes that match the key-value pair.

To associate pods to the nodes through the labels, use the following configuration:

config 
  k8 label 
    cdl-layer   
      key key_value 
      value value 
    oam-layer   
      key key_value 
      value value 
    protocol-layer   
      key key_value 
      value value 
    service-layer   
      key key_value 
      value value 
    sctp-layer   
      key key_value 
      value value 
      end

NOTES:

label { cdl-layer { key key_value | value value } —Specify the key value pair for CDL.
oam-layer { key key_value | value value } —Specify the key value pair for OAM layer.
protocol-layer { key key_value | value value } —Specify the key value pair for protocol layer.
service-layer { key key_value | value value } —Specify the key value pair for the service layer.
sctp-layer { key key_value | value value } —Specify the key value pair for the SCTP layer.

Note

If you opt not to configure the labels, then AMF assumes the labels with the default key-value pair.

Viewing the Pod Details and Status

If the service requires additional pods, AMF creates and deploys the pods. You can view the list of pods that are participating in your deployment through the AMF Ops Center. You can run the kubectl command from the master node to manage the Kubernetes resources.

To view the comprehensive pod details, use the following command.

kubectl get pods -n 
                                       amf_namespace
                                       pod_name
                                       -o yaml

The pod details are available in YAML format. The output of this command results in the following information:

The IP address of the host where the pod is deployed.
The service and application that is running on the pod.
The ID and name of the container within the pod.
The IP address of the pod.
The current state and phase in which the pod is.
The start time from which pod is in the current state.

States

Understanding the pod's state lets you determine the current health and prevent the potential risks. The following table describes the pod's states.

Table 6. Pod States
State	Description
Running	The pod is healthy and deployed on a node. It contains one or more containers
Pending	The application is in the process of creating the container images for the pod
Succeeded	Indicates that all the containers in the pod are successfully terminated. These pods cannot be restarted.
Failed	One ore more containers in the pod have failed the termination process. The failure occurred as the container either exited with non zero status or the system terminated the container.
Unknown	The state of the pod could not be determined. Typically, this could be observed because the node where the pod resides was not reachable.
