The vci-virtual-kubelet add-on schedules and runs Volcengine Container Instance (VCI) instances through virtual nodes. Virtual nodes are created by default after the add-on is deployed.Virtual nodes are created by default after the add-on is deployed. This topic mainly describes the change history of the vci-virtual-kubelet add-on.
