Get ENI IDs from a fargate task in python

__main__.py

# private IP
# we created the security group, so we use that to retrieve the ENI addresses.
# this like returns one per subnet associated with the fargate task
eni = aws.ec2.get_network_interfaces_output(
    filters=[{
        "name": "group-id",

        private_ips.append(eni.private_ip)

# we need to wait for the ENI results to return from the API,
# so inside an apply, we loop through the values and then retrieve the private IP
