Kubernetes Client Provider#

Overview#

The Kubernetes Client Provider publishes metadata about Kubernetes pods into the EDA networks client table.

The provider authenticates to the cluster API, watches Pods, NetworkAttachmentDefinitions, and kubernetes-nmstate NodeNetworkState, and writes provider-k8s-pod entries. The Networks Client Provider then supplies fabric-learned MAC and IP data for the same clients.

Supported Versions#

The Kubernetes Client Provider supports the same platforms as the Kubernetes plugin:

• Red Hat OpenShift 4.18
• Red Hat OpenShift 4.20
• Red Hat OpenShift 4.22

The installation of the Kubernetes plugin on the target cluster is mandatory.

Architecture#

The Kubernetes Client Provider is an EDA application. It is separate from the Kubernetes plugin, which runs on the target cluster instead.

Each K8sClientProviderInstance starts one operator pod that connects to one Kubernetes cluster and publishes client-table rows for the spec.namespace namespace.

Installation#

For detailed deployment instructions, see the Kubernetes Client Provider Installation Guide.

Features#

Inventory#

The provider publishes one pod row per network attachment and IP. Each published pod row requires:

• A MAC address
• An IP address
• A BridgeDomain

The BridgeDomain comes from the Connect Kubernetes plugin after it has synchronized the NetworkAttachmentDefinition.

Pods with more than one attachment will appear as multiple rows.
