CIDR Blocks and Container Engine for Kubernetes

When configuring the VCN and the worker node and load balancer subnets for use with Container Engine for Kubernetes, you specify CIDR blocks to indicate the network addresses that can be allocated to the resources. See Network Resource Configuration for Cluster Creation and Deployment.

When creating a cluster with Container Engine for Kubernetes, you specify:

Note the following:

  • The CIDR block you specify for the VCN must not overlap with the CIDR block you specify for the Kubernetes services.
  • The CIDR blocks you specify for pods running in the cluster must not overlap with CIDR blocks you specify for worker node and load balancer subnets.
