Usage restrictions
Updated at:2025-10-27
This document introduces cloud products and their associated limitations that may arise while using the Cloud Container Engine (CCE) Kubernetes cluster. You can make unified adjustments as needed to avoid issues caused by quota restrictions.
K8S Cluster CCE Quota Limits
| Limitation items | Default quota | Can I increase quota? |
|---|---|---|
| Cluster quota in each region | 20 counts | Supported. You may submit a ticket to request quota increase |
| Single cluster node size | 200 counts | |
| Single cluster snapshot quota | 50 counts |
Note: You can view current quota and used cluster on the Cloud Container Engine (CCE)Console.

Example of quota requirements for could products in typical scenarios
Scenario 1: Product and resource quantities required to create 1,000 postpay BCC nodes in VPC route mode, where one 100 GB system disk and two 200 GB data disks are mounted to each node
Example:
Limit categories | Dependency on cloud products | Limitation items | Default quota | Actual required count | Whether to adjust the default quota? |
Cloud native | Cloud Container Engine (CCE) | Single cluster node size | 200 | 1000 | Yes |
Compute | Baidu Cloud Compute (BCC) | Count of postpaid BCC instances in each region | 50 | 1000 | Yes |
Network | Route table | Count of route rules that can be added for each route table | 50 | 1000 | Yes |
Security group | Count of instances associated with each regular security group | 100000 | 1000 | No | |
Storage | Cloud Disk Server (CDS) | Total count of cloud disks in each region | 160TB | 500TB | Yes |
Count of CDS instances in each region | 5000 | 3000 | No | ||
Maximum count of data disks that can be mounted to each Baidu Cloud Compute (BCC) | 5 | 3 | No |
Scenario 2: Create 100 LB Services, 1,000 pods are associated with each service backend (direct pod mode), and a standard EIP with 1,000 Mbps bandwidth and billing by traffic is mounted to each BLB
Example:
Limit categories | Dependency on cloud products | Limitation items | Default quota | Actual required count | Whether to adjust the default quota? |
Network | Elastic IP (EIP) | Count of standard BGP EIP instances in each region | 50 (individual users), 130 (enterprise users) | 100 | Yes(individual users) |
Maximum bandwidth peak for a single standard BGP EIP | 200Mbps | 1000Mbps | Yes | ||
Total peak bandwidth of all pay-by-traffic standard BGP EIPs in a single region | 5000Mbps | 100000Mbps | Yes | ||
Baidu Load Balancer (BLB) | Count of BLB instances in each region | 60 | 100 | Yes | |
Count of listeners that can be added in each BLB instance | 50 | 1 | No | ||
Count of members of IP group per application BLB instance | 50 | 1000 | Yes | ||
