Quota Limits for Cluster Purchase

Last updated: 2021-01-29 17:49:26

    Each user is assigned a fixed quota for TKE clusters in each region.

    TKE quota limits

    The following describes the number of container clusters each user can purchase. If you need more clusters, submit a ticket.

    Note:

    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

    CVM quota limits

    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

    Note:

    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
    • No
    • Yes, and you can create new subnets
    CIDR block of the container IP range Custom
    • Maximum nodes per cluster
    • Maximum services per cluster
    • Maximum pods per node
    Basic information page for the cluster - Container IP address range No

    Resource quota limits

    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.
