provides a single IP address and DNS name by which the pods can be accessed. This load balancing configuration is much easier to manage, and helps scale pods seamlessly. Volume A volume is a directory API server which provides all CRUD operations on cluster through a API. • proxy is another component which is running on every node in Kubernetes cluster and provides a simple network and load balancer complete Guestbook application: • Service definitions for: o FrontEnd component : o Redis Master o Redis Slave component • Deployment definitions for: o Front End o Redis Master o Redis Slave

from the cloud to core and at the edge. Each distribution requires the bare minimum of host configuration, usually no more than a supported version of Docker. For edge deployments, SUSE Rancher does Kubernetes in the most efficient way possible. Kubernetes from SUSE Rancher with RKE uses a configuration syntax designed for clarity and dynamic cluster reconfiguration with no downtime. 3.1.1.2 application clusters happens through the installer GUI or via command-line directives that use a YAML configuration file. Clusters can run on vSphere, Amazon, Microsoft Azure or GCP nodes if operators choose to

deployments • Highly available and resilient network controller overseeing all aspects of the network configuration and control planes • Analytics services using telemetry and industry standard monitoring and facilitates virtual network abstraction, orchestration, and automation. Network configuration plane The network configuration plane interacts with Kubernetes control plane components to manage all CN2 resources send and receive network traffic. Its main component is the Contrail vRouter. Contrail controller This is the part of CN2 that provides the network configuration and network control plane functionality.
