VCN-Native Pod Networking CNI plugin version 2.3.0 now available

The OCI VCN-Native Pod Networking CNI plugin for use with Kubernetes Engine (OKE) includes the following new features and functionality in version 2.3.0:

• The CNI plugin now uses the OnDelete update strategy instead of the RollingUpdate strategy (for more information, see DaemonSet Update Strategy in the Kubernetes documentation). The CNI plugin pods are updated only when they are explicitly deleted. This approach avoids unexpected restarts of the CNI plugin pods during cluster updates.
• A new validating admission policy now restricts deletion of CNI plugin pods. To update the CNI plugin to a newer version, do one of the following:
  • Provision new nodes: New nodes automatically receive CNI plugin pods running the latest CNI plugin version.
  • Update existing nodes: Remove the validating admission policy, delete the existing CNI plugin pods, and recreate the policy. The DaemonSet controller creates new CNI plugin pods that are running the latest version of the CNI plugin.
• Bug fixes to improve reliability.
