Limits on the Number of Pods in VPC-CNI Mode

Last updated: 2022-07-11 10:11:46

    The following displays the default limits on the number of Pods in each network mode of VPC-CNI.

    Limits on the Number of Pods with Shared ENI

    The number of Pods with shared ENI is limited by the number of ENIs that can be bound to a node and the number of IPs that can be bound on a single ENI. By default, *the maximum number of Pod IPs on a single node with multiple ENIs = the maximum number of secondary ENIs that can be bound * the number of secondary IPs that can be bound on a single ENI*, and the maximum number of Pod IPs on a single node with a single ENI = the number of secondary IPs that can be bound on a single ENI. See the table below for details.

    The number of secondary IPs that can be bound on a single ENI591929
    The maximum number of Pod IPs on a single node (with multiple ENIs) in non-static IP address mode52795203
    The maximum number of Pod IPs on a single node (with a single ENI) in static IP address mode591929

    The number of ENIs that can be bound to each model and the number of IPs that can be bound on a single ENI is slightly different. For details, see Use Limits.

    Limits on the Number of Pods with Exclusive ENIs

    The number of Pods with exclusive ENIs is only limited by the number of ENIs that can be bound to the node. It only supports some models such as S5, SA2, IT5 and SA3. See the table below for details.
