Adding a Container CIDR Block for a Cluster
Scenario
If the container CIDR block (container subnet in a CCE Turbo cluster) set during CCE cluster creation is insufficient, you can add a container CIDR block for the cluster.
Constraints
- This function applies to CCE standard clusters and CCE Turbo 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 Standard Cluster
- Log in to the CCE console and click the cluster name to access the cluster console.
- On the Overview page, locate the Networking Configuration area and click Add Container CIDR Block.
Figure 1 Adding container CIDR block
- 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.
Figure 2 Configuring the container CIDR block - Click OK.
Adding a Container Subnet for a CCE Turbo Cluster
- Log in to the CCE console and access the CCE Turbo cluster console.
- On the Overview page, locate the Networking Configuration area and click Add Pod Subnet.
Figure 3 Adding a pod subnet
- Select a container subnet in the same VPC. You can add multiple container subnets at a time. If no other container subnet is available, go to the VPC console to create one.
Figure 4 Selecting a pod subnet
- Click OK.
