[SOLVED] Custom endpoint in AWS powershell

Custom endpoint in AWS powershell

I am trying to use AWS Powershell with Eucalyptus.

I can do this with AWS CLI with parameter --endpoint-url.

Is it possible to set endpoint url in AWS powershell? Can I create custom region with my own endpoint URL in AWS Powershell?

Solution

--UPDATE--

The newer versions of the AWS Tools for Windows PowerShell (I'm running 3.1.66.0 according to Get-AWSPowerShellVersion), has an optional -EndpointUrl parameter for the relevant commands.

Example:

Get-EC2Instance -EndpointUrl https://somehostnamehere

Additionally, the aforementioned bug has been fixed.

Good stuff!

--ORIGINAL ANSWER--

TL;TR

Download the default endpoint config file from here: https://github.com/aws/aws-sdk-net/blob/master/sdk/src/Core/endpoints.json

Customize it. Example:

{
    "version": 2,
    "endpoints": {
        "*/*": {
            "endpoint": "your_endpoint_here"
        }
    }
}

After importing the AWSPowerShell module, tell the SDK to use your customized endpoint config. Example:
```
[Amazon.AWSConfigs]::EndpointDefinition = "path to your customized Amazon.endpoints.json here"
```

Note: there is a bug in the underlying SDK that causes endpoints that have a path component from being signed correctly. The bug affects this solution and the solution @HyperAnthony proposed.

Additional Info

Reading through the .NET SDK docs, I stumbled across a section that revealed that one can global set the region rules given a file: http://docs.aws.amazon.com/AWSSdkDocsNET/latest/V2/DeveloperGuide/net-dg-config-other.html#config-setting-awsendpointdefinition

Unfortunately, I couldn't find anywhere where the format of such a file is documented.

I then splunked through the AWSSDK.Core.dll code and found where the SDK loads the file (see LoadEndpointDefinitions() method at https://github.com/aws/aws-sdk-net/blob/master/sdk/src/Core/RegionEndpoint.cs).

Reading through the code, if a file isn't explicitly specified on AWSConfigs.EndpointDefinition, it ultimately loads the file from an embedded resource (i.e. https://github.com/aws/aws-sdk-net/blob/master/sdk/src/Core/endpoints.json)
