Support for regional subnets

You can now create Kubernetes clusters with worker nodes and load balancers in regional subnets. When defining an application's network requirements, you now have the flexibility to divide a Virtual Cloud Network (VCN) into subnets for efficiency, whilst at the same designing the VCN to withstand Availability Domain (AD) failure.

Oracle recommends the use of regional subnets for your Kubernetes environment. And taking advantage of the new regional subnet support, the 'Quick Create' workflow now creates regional subnets for your worker nodes and load balancers. However, if you prefer to create worker nodes and load balancers in AD-specific subnets, use the 'Custom Create' workflow. That workflow now supports both AD-specific subnets and regional subnets.
