    Elastic Compute Service：LeaveSecurityGroup

    更新時間：Dec 24, 2024

    Removes an Elastic Compute Service (ECS) instance or an elastic network interface (ENI) from a security group.

    Operation description

    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.
    Note Alibaba Cloud modified verification rules for the LeaveSecurityGroup operation on July 8, 2024. When you remove an ECS instance or ENI that does not belong to a security group from the security group, the "InvalidSecurityGroupAssociation.NotFound" error code is returned instead of a success response. Update the LeaveSecurityGroup operation to use the new verification rules with the new error code based on your business requirements.
    • You cannot remove an instance and an ENI from a security group at the same time. This indicates that you cannot specify InstanceId and NetworkInterfaceId in one request.
    • Before you remove an instance from a security group, the instance must be in the Stopped (Stopped) or Running (Running) state.
    • An instance or ENI must be added to at least one security group. If you remove an instance or ENI from the only security group, the removal request fails and an error is returned.
    • When you remove an instance or ENI that is not in a security group from the security group, the removal request fails and an error is returned.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
