IAM lightsail user restrict access to specific VM instances

Question

I am trying to restrict access to only one VM instance in lightsail.

Using a policy

When trying: "Resource": "arn:aws:lightsail:us-west-2:xxxxxxxxxxxxx:Instance/xxxxxx-xxxx-xxxx-xxxx-xxxxxxxx"

I get a 403 error?

If I use:

"Resource": "*"

IAM user can see all the VMs

I got my resource name above (obviously with out the "x's) from the command line using: aws lightsail get-instances

Accepted Answer

What IAM policies have you set up?  
The following documentation shows that only a limited number of "Instances" can be set to "Resource".  
https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonlightsail.html#amazonlightsail-actions-as-permissions

For example, the following IAM policy will allow you to view all Lightsail instances, but restrict instance operations to those instances configured in "Resource".  
```
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "lightsail:*",
            "Resource": "arn:aws:lightsail:us-west-2:xxxxxxxxxxxxx:Instance/xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx"
        },
        {
            "Effect": "Allow",
            "Action": "lightsail:Get*",
            "Resource": "*"
        }
    ]
}
```

Tags can be used to filter access to Lightsail resources https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-controlling-access-using-tags

Answer

For example, just want the IAM user to see the server on the left.

Answer

That worked, thank you!

However, the current IAM user can still see all the Lightsail VM's of the root account (even though they can not control it) Is there a way to restrict this access so they only see the designated resource in the policy?

Perhaps giving an outside IAM user (not under root) access to the Lightsail resource?
