    Elastic Compute Service：JoinSecurityGroup

    更新時間：Sep 29, 2024

    Adds an Elastic Compute Service (ECS) instance or an elastic network interface (ENI) to a security group. When you call this operation, you can specify parameters, such as SecurityGroupId, InstanceId, and NetworkInterfaceId, in the request.

    Operation description

    Usage notes

    Note This operation is not recommended. We recommend that you call the ModifyInstanceAttribute operation to add an instance to or remove an instance from a security group, and call the ModifyNetworkInterfaceAttribute operation to add an ENI to or remove an ENI from a security group.

    Take note of the following items:

    • Before you add an instance to a security group, the instance must be in the Stopped (Stopped) or Running (Running) state.
    • An instance can be added to up to five security groups by default.
    • You can submit a ticket to change the maximum number of security groups to which an instance can be added to 4 or 10.
    • A basic security group can contain up to 2,000 instances. An advanced security group can contain up to 65,536 instances.
    • The security group and the instance must reside in the same region.
    • The security group and the instance must be of the same network type. If the network type is Virtual Private Cloud (VPC), the security group and the instance must reside in the same VPC.
    • An instance and an ENI cannot be added to a security group at the same time. You cannot specify InstanceId and NetworkInterfaceId at the same time in a request.
