copy_snapshot does not copy snapshot from region A to region B

[th3b3ginn3r]

Describe the issue

The example section of the Boto3 document shows that it is possible to copy a snapshot from one region to another using the copy_snapshot API.

https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/ec2/client/copy_snapshot.html

However, when I try to copy a snapshot from the region ap-northeast-1 to us-west-2, it still copies the snapshot in the source region.

Request

session = boto3.Session(profile_name="xxxxxx")
client = session.client("ec2", region_name="ap-northeast-1")
response = client.copy_snapshot(
    Description="This is my copied snapshot.",
    DestinationRegion="us-west-2",
    SourceRegion="ap-northeast-1",
    SourceSnapshotId="snap-025fedd32e88507f3",
)

Response

{'SnapshotId': 'snap-02b6c46a14a7b4eda', 'ResponseMetadata': {'RequestId': 'cc0490e8-3692-4905-9935-36a1bd725eb6', 'HTTPStatusCode': 200, 'HTTPHeaders':.......}

Hi @th3b3ginn3r, thanks for reaching out. There is actually a section in the docs that addresses this behavior.

The destination Region to use in the PresignedUrl parameter of a snapshot copy operation. This parameter is only valid for specifying the destination Region in a PresignedUrl parameter, where it is required.

The snapshot copy is sent to the regional endpoint that you sent the HTTP request to (for example, ec2.us-east-1.amazonaws.com). With the CLI, this is specified using the --region parameter or the default Region in your Amazon Web Services configuration file.

So, in order to make this copy work, you need to run your script from the DestinationRegion, us-west-2 in the example you provided.

Hope that helps, please let me know if you have any follow-up questions.
