Sveltos is a project to deploy Kubernetes add-ons in tens of managed clusters from a management cluster. We have already covered few aspects on Sveltos in different posts: Deploy Kubernetes add-ons based on cluster run-time state; Kubernetes multi-tenancy with Sveltos; L4-L7 with Sveltos. In this post, we will cover how…
