Adding a Container CIDR Block for a Cluster

Scenario

If the container CIDR block set during CCE cluster creation is insufficient, you can add a container CIDR block for the cluster.

Constraints

• This function applies to CCE clusters of v1.19 or later, but not to clusters using container tunnel networking.
• The container CIDR block or container subnet cannot be deleted after being added. Exercise caution when performing this operation.

Adding a Container CIDR Block for a CCE Cluster

1. Log in to the CCE console and click the cluster name to access the cluster console.
2. On the Cluster Information page, click Add Container CIDR Block in the Networking Configuration area.
3. Configure the container CIDR block to be added. You can click to add multiple container CIDR blocks at a time.
   

   New container CIDR blocks cannot conflict with service CIDR blocks, VPC CIDR blocks, and existing container CIDR blocks.

4. Click OK.
