Kubernetes - Project Calic

Most Calico installations in the past have been manifest-based, meaning that Calico is installed directly as a set of Kubernetes resources in a .yaml file. The Calico operator is a Kubernetes application that installs and manages the lifecycle of a Calico installation by creating and updating Kubernetes resources such as Deployments, DaemonSets. Installing Calico on Kubernetes can be simple or complex depending whether to use Calico for policy and network management or just policy. The installation consists of applying a Kubernetes manifest file against the cluster. By default, Calico assumes the internal IP address inside the Kubernetes cluster to be 192.168../24 Project Calico is an open source networking and security solution. Although it focuses on securing Kubernetes networking, Calico can also be used with OpenStack and other workloads. Calico uses a modular data plane that allows a flexible approach to networking, providing a solution for both current and future networking needs Configuring Calico to use Typha¶. As of kOps 1.12 Calico uses the kube-apiserver as its datastore. The default setup does not make use of Typha —a component intended to lower the impact of Calico on the Kubernetes API Server which is recommended in clusters over 50 nodes and is strongly recommended in clusters of 100+ nodes
