Each user is assigned a fixed quota for TKE clusters in each region.
The following describes the number of container clusters each user can purchase. If you need more clusters, submit a ticket.
Since October 21, 2019, the maximum number of nodes supported in a cluster has been increased to 5,000.
|Quota Item||Default Value||Where to Check||Support Quota Increase|
|Clusters in a single region||5||Bottom-right section of the TKE overview page||Yes|
|Nodes in a single cluster||5,000|
|Image namespaces in a single region||10|
|Image repository in a single region||500|
|Image tags for a single image||100|
For CVM instances that you purchase for Tencent Cloud TKE, CVM purchase limits apply. For more information, see CVM Instance Purchase Limits. See the following table for the maximum number of CVMs that a user can purchase by default. If you need a higher quota for any item, submit a ticket.
|Quota Item||Default Value||Where to Check||Support Quota Increase||Pay-as-you-go CVMs in a single availability zone||30 - 60||CVM Instances page - Resources in each region||Yes|
Cluster configuration limits the size of clusters and cannot be modified currently.
|Configuration Item||IP Address Range||Affected Item||Where to Check||Support Modification|
|VPC network - Subnet||Custom||Number of nodes that can be added||VPC subnet list page for the cluster - Available IP addresses||
|CIDR block of the container IP range||Custom||
||Basic information page for the cluster - Container IP address range||No|
From January 13, 2021, TKE will automatically apply a set of resource quotas to the namespace on the cluster with less than 5 nodes (0 < nodeNum ≤ 5), or with more than 5 and less than 20 nodes (5 < nodeNum < 20). You cannot remove these quotas, which are used to protect the cluster control plane from being unstable due to potential bugs in the applications deployed to the cluster.
You can run the following command to check the quota:
kubectl get resourcequota tke-default-quota -o yaml
If you need to view the
tke-default-quota object of a specified namespace, you can add the
--namespace option to specify the namespace.
The specific quota limits are as follows:
|Cluster Scale||Quota Limits|
|0 < nodeNum ≤ 5||Total Pods: 4000, configMap: 3000, CustomResourceDefinition(CRD): 4000|
|5 < nodeNum < 20||Total Pods: 8000, configMap: 6000, CustomResourceDefinition(CRD): 8000|
|20 ≤ nodeNum||No limit|
You can submit a ticket to apply to increase the quota.
