Kubernetes Updated to 1.17: Kubernetes 1.17 is the default release installed on nodes in a new cluster in an Oracle Linux Cloud Native Environment.

Existing Kubernetes Release 1.14 deployments can be upgraded to Release 1.17. For more information about upgrading to Release 1.1, see Updates and Upgrades.

Kubernetes Cluster Scaling: The olcnectl module update command is enhanced so that you can now scale a Kubernetes cluster by either adding master and worker nodes to it or removing master and worker nodes from it.

For more information about using the olcnectl module update command to scale a Kubernetes cluster, see Getting Started at:

https://docs.oracle.com/en/operating-systems/olcne/1.1/start/scale.html

Service Mesh: A new module is available to deploy a service mesh to a Kubernetes cluster. The Istio module for Oracle Linux Cloud Native Environment deploys a service mesh in Oracle Linux Cloud Native Environment. Grafana is deployed as part of the service mesh.

For more information about deploying and using a service mesh, see Service Mesh. For more information about using Grafana, see Monitoring and Visualization.

Firewall Changes: Masquerading no longer needs to be enabled in the firewall on Kubernetes nodes. Instead, the cni0 interface must be added to the trusted zone on nodes.

For more information on firewall requirements for Kubernetes nodes, see Getting Started at:

https://docs.oracle.com/en/operating-systems/olcne/1.1/start/ports.html

Installation Change: A new ULN channel (ol7_x86_64_olcne11) and a new Oracle Linux yum server repository (ol7_olcne11) are available for installing the Oracle Linux Cloud Native Environment Release 1.1 packages. Use this new channel or repository to install or upgrade to Release 1.1.
