Stretching CNI Boundaries with Service Meshes, a Roadmap for the Future - Alex Leong, Buoyant

Container Network Interface (CNI) plugins such as Calico or Cilium are typically used to provide container network connectivity and network policy. However, service meshes such as Linkerd and Istio also use CNI plugins to configure the networking rules that allow their sidecar proxies to intercept incoming and outgoing traffic. This means that it is increasingly common to have more than one CNI plugin installed at a time, which can lead to race conditions where the CNI plugins overwrite each other's configuration. In this talk, Alex Leong will demonstrate how to detect and resolve these problems and suggest a set of best practices for CNI plugins to ensure compatibility with other plugins. She'll also explore some potential changes to the CNI plugin specification, which could solve these problems at a structural level.
