aws opsworks associate-elastic-ip fails

Question

I'm trying to allocate an elastic IP to an existing instance in ap-southeast-2 (Sydney) using this command:
aws opsworks --profile COMPANY --region ap-southeast-2 associate-elastic-ip --instance-id $IID --elastic-ip $EIP
and it fails with this error message:
An error occurred (ResourceNotFoundException) when calling the AssociateElasticIp operation: Unable to find elastic ip with ID 999.999.999.999

I'm running this on Linux from the CLI.  I export the instance id and the elastic IP to the 2 variables and i've verified that they exist and are available.  I've also verified that the --profile is valid as I can run the aws ec2 describe-addresses using that profile id.  I've also tried using the actual IP instead of the variable and it gives the same error.

Any insight?  This seems to be a very simple command but I can't make it work.  Thanks.

Accepted Answer

I get the same error in the same region, and I'm wondering if it's because I'm trying it with a brand new instance that isn't registered with an OpsWorks stack (and I'm not able to register a new stack because OpsWorks is EOL https://docs.aws.amazon.com/opsworks/latest/userguide/stacks-eol-faqs.html ).

Is your instance registered to an existing OpsWorks stack?

Using `aws ec2` rather than `aws opsworks` is fine using the same instance and EIP, but I'm guessing you have a good reason for wanting to use OpsWorks.

```
$ aws opsworks --region ap-southeast-2 associate-elastic-ip --instance-id i-0635149fxyzxyzxyz --elastic-ip 13.x.y.z

An error occurred (ResourceNotFoundException) when calling the AssociateElasticIp operation: Unable to find elastic ip with ID 13.x.y.z
$ aws ec2 associate-address --region ap-southeast-2 --instance-id i-0635149fxyzxyzxyz --public-ip 13.x.y.z
{
    "AssociationId": "eipassoc-0f5ceba5xyzxyzxyz"
}
$
```

Answer

Steve,
While you didn't solve the opsworks problem, you did show me that I overlooked the obvious solution in ec2 associate-address.  So thanks very much.
