New features
Greatly improved Support for logging and backup solutions
We have added an opt-in feature for vcluster which allows us to support logging solutions like ELK, fluentd, loki etc. deployed inside the vcluster. Along with these we also enable support for backup solutions like velero and VM solutions like kubevirt. These applications mount the host paths such as "/var/log" or "/var/lib/kubelet/pods" to retrieve information about workloads in the cluster. You can ensure that the expected data are made available to these applications by enabling the "Hostpath Mapper" feature of vcluster.
High availability support for k3s with external datastore
vcluster now supports HA for the default k3s distro. This is a new alternative to our existing HA support with the k8s distro of vcluster. However it currently requires an external datastore to be configured. New chapter of the HA documentation page describes how to install vcluster with HA k3s - https://www.vcluster.com/docs/operator/high-availability#k3s
Automatically sync CSI resources when scheduler is enabled.
When vcluster scheduler is enabled, the vcluster will start syncing additional storage-related resources to make correct scheduling decisions. These resources are - CSIStorageCapacity, CSINode, and CSIDriver. You can disable this as described in the documentation.
Important changes
- The "legacy-storageclasses" syncer was renamed to "hoststorageclasses". If you have enabled the "legacy-storageclasses" syncer, we highly recommend to update your helm values to reference the new name:
sync:
hoststorageclasses:
enabled: true
