Response parameters

Fn::GetAtt

InstanceIds: the IDs of the instances. An instance ID is a GUID that is generated by the system for an instance.
PrivateIps: the private IP addresses of ECS instances in VPCs. This parameter takes effect if the NetworkType property is set to vpc. Example: ["172.16.XX.XX", "172.16.XX.XX", … "172.16.XX.XX"]. In this example, the value is a JSON array that can contain up to 100 IP addresses separated by commas (,).
InnerIps: the private IP addresses of ECS instances in the classic network. This parameter takes effect if the NetworkType property is set to classic. Example: ["10.1.XX.XX", "10.1.XX.XX", … "10.1.XX.XX"]. In this example, the value is a JSON array that can contain up to 100 IP addresses separated by commas (,).
PublicIps: the public IP addresses of ECS instances in the classic network. This parameter takes effect if the NetworkType property is set to classic. Example: ["42.1.XX.XX", "42.1.XX.XX", … "42.1.XX.XX"]. In this example, the value is a JSON array that can contain up to 100 IP addresses separated by commas (,).
HostNames: the hostnames of the ECS instances.
OrderId: the order ID of the ECS instances.
ZoneIds: the zone IDs of the ECS instances.
Ipv6AddressIds: the IDs of IPv6 addresses of the ECS instances.

Note The IDs of IPv6 addresses are returned in a list that has two levels of nesting. If an ECS instance does not have an IPv6 address, the element at the relevant position in the list is empty. If none of the ECS instances have an IP address, null is returned.
Ipv6Addresses: the IPv6 addresses of the ECS instances.

Note The IPv6 addresses are returned in a list that has two levels of nesting. If an ECS instance does not have an IPv6 address, the element at the relevant position in the list is empty. If none of the ECS instances have an IP address, null is returned.
