Few questions in this regard.
First, which CNI plugins are officially supported in Azure. As far as I understand kubenet and azure-cni can be used, as they are options in AKS/acs-engine. Is this a correct statement?
Second - which CNIs can be used, like calico, flannel etc. Which can be safely used, and which cannot be used safely.
At the moment azure-cni and kubenet are the only officially supported CNIs. However, acs-engine supports wider variety of CNI plugins, but they are not for Azure
