(aws-appmesh): priority cannot be configured in gateway routes

[desoss]

What is the problem?

Even if the AWS console allows to specify the gateway route priority in the gateway route configuration this is not possible in CDK.

Reproduction Steps

Here I've no way to specify the priority of a gateway route.

virtualGateway.addGatewayRoute('trial-route', {
    gatewayRouteName: 'trial-route',
    routeSpec: appmesh.GatewayRouteSpec.http({
        match: {
            path: HttpGatewayRoutePathMatch.startsWith('/'),
            rewriteRequestHostname: false,
        },
        routeTarget: props.targetService,
    })
});

What did you expect to happen?

I expect to be able to configure the gateway route priority as in the console:

What actually happened?

Currently, the priority cannot be configured in the gateway routes.

@desoss - thank you very much for reporting the issue and I am very sorry for the inconvenience you are facing.

I am taking a looking a look at this issue we will respond by end of today with updates.

I am confirming CDK is currently not allowing Gateway Route to configure Priority.

I verified that the App Mesh console as well as AWS CLI does allow configuring Gateway Route with Priority.

However, CloudFormation GAtewayRouteSpec does not contain a field for Priority.

I am further getting confirmation if this is the bug/miss.

@desoss - We've verified Priority field is missing from CloudFormation spec and thus not showing in CDK as well.
We are working on fixing this issue and I will update this thread again once we identify estimated date of completion.

Meanwhile, as a workaround, please consider taking one of the below steps:

• Create Gateway Route using CDK and configure Priority field using AWS console
• Create Gateway Route using either AWS console or AWS CLI

Again, we deeply apologize for the inconvenience.

Thanks, @Seiya6329 .
Is it possible to have an estimation on when the fix will be released?

So that we can decide if it's worth investing some time in an AWS CLI script or not.

[Seiya6329]

@desoss - we are looking at 1.0 - 1.5 month to deploy all changes.

[Seiya6329]

Quick update: We are deploying changes to CloudFormation to include Priority field.

I think we are looking at end of November as a target for full CDK update completion.

[Seiya6329]

Priority field is now available in CloudFormation. (link)
It should be becoming available for CDK L1 this week.

For CDK L2 support, we are still at end of November.

Submitted the PR for supporting Gateway Route Priority in CDK L2 construct: #17694
