Throughout the webinar we’ll demo pertinent aspects of Kubernetes, F5 BIG-IP, and NGINX related to networking and support of Kubernetes resources. Lastly, we’ll look at how NGINX Ingress Controller differs from the Kubernetes project NGINX Ingress Controller (yes, same name, different authors) in supporting the Kubernetes Ingress resource type for L7 routing of HTTP and HTTPS traffic. Kubenet is a very basic network provider, and basic is good, but does not have very many features. Kubernetes default networking provider, kubenet, is a simple network plugin that works with various cloud providers. Multus CNI (Container Network Interface) is a novel approach to managing multiple CNIs in your container network (Kubernetes).Based on its name, which means multiple in Latin, Multus is an open-source plug-in, which serves as an additional layer in a container network, to enable multi-interface support. We’ll approach this from a networking perspective of understanding how Kubernetes has its own Container Network Interface (CNI) that is used to facilitate communication between pods (containers). Next, we’ll look at the Kubernetes Service type to understand how the choice of “ClusterIP,” “NodePort,” “HostPort,” and “LoadBalancer” can affect the availability of a service and its performance. We’ll also look at the “Ingress” resource type and how it’s used to provide L7 (content-routing) of HTTP and HTTPS traffic.Īfter looking at the internals of how Kubernetes operate, we’ll learn how BIG-IP interacts with a Kubernetes cluster using NodePort or via a CNI like Flannel or Calico (VXLAN/BGP). This interaction is facilitated by the use of F5 Container Ingress Services to automate the configuration of the BIG-IP instance. Kubernetes uses CNI as an interface between network providers and Kubernetes networking. In this webinar, you’ll learn how Kubernetes makes applications available outside of a Kubernetes cluster.
