Can the Container CIDR Block Be Modified After a Cluster Is Created?

After a cluster and containers are created, the network configuration cannot be modified. Properly plan network CIDR blocks before creating a cluster. For details, see Planning CIDR Blocks for a CCE Cluster

Explanation

Network parameters are configured when a namespace is created. That is, to change the network configuration, you need to create a namespace, configure the network adaptation, and then migrate the application to the new namespace. Currently, CCE does not support the migration of running services to a new CIDR block. You can delete applications and re-plan network information.
