What is flannel?
Flannel acts as a dedicated virtual networking layer specifically designed for containerized applications. When working within the OpenShift Container Platform, it can serve as an alternative networking solution to the conventional software-defined networking (SDN) components. This method proves especially beneficial for OpenShift deployments in cloud settings that also utilize SDN technologies, such as OpenStack, by eliminating the need for redundant packet encapsulation between the two systems. Each flanneld agent is responsible for sending information to a centralized etcd store, which allows other agents on different hosts to efficiently route packets to various containers within the flannel network. Furthermore, the accompanying diagram illustrates the architecture and data flow that facilitate communication among containers operating over a flannel network. This configuration not only boosts overall network performance but also streamlines the management of containers in intricate environments, ultimately leading to better resource utilization and operational efficiency.
