Calico-Node

Definition

Calico node is a component of Kubernetes that provides networking and network policy enforcement for pods within the cluster. It enables administrators to easily configure and manage pod-to-pod communication, as well as providing full Layer 3 networking. Additionally, Calico node allows network operators to construct robust network security policies to isolate services running within their cluster.

Components

The components of Calico Typha include

• Typha agent,
• Typha configurer,
• Loadbalancer, and
• the associated Kubernetes services

The Typha agent provides a service for packets to be routed across multiple nodes in the cluster,

while theTypha configurer ensures that the policies associated with each node are properly configured.

The Loadbalancer provides a service to manage connections from the exterior of the cluster to the individual pods,

while the associated Kubernetes services enable communication between the various components of the Calico Typha system.
