Cloudformation-coverage-roadmap: AWS::ElasticLoadBalancingV2::TargetGroup-ProtocolVersion

[intercept6]

2. Scope of request

AWS::ElasticLoadBalancingV2::TargetGroup-ProtocolVersion can create resources via API, but not via CloudFormation.

ElasticLoadBalancingV2 CreateTargetGroup now supports the ProtocolVersion parameter for gRPC or HTTP2. CloudFormation needs support for this as well.

3. Expected behavior

In Create, it should include the ProtocolVersion, like the console.

5. Helpful Links to speed up research and evaluation

• Updated API docs at https://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_CreateTargetGroup.html

6. Category (required) - Will help with tagging and be easier to find by other users to +1

1. Networking & Content (VPC, Route53, API GW,...)

When will this be available?

I have created a custom resource to do this in the meantime; if anyone is interested i'm happy to share it.

If you wouldn't mind please Dennis. Thanks

@dennisroche I would be very happy to see that too. I tried to create my own but it looks like the API doesn't allow to modify the Protocol Version on an existing TargetGroup at all.

Update requires Replacement, i.e. ProtocolVersion can only set on creation.

I have created a minimal example of HTTP2 Target Group custom resource https://gist.github.com/dennisroche/287915ca6a0874157d71b0903ec3999b

Luckily it turned out - with the help of the AWS Support - that it's only a documentation issue. You can use the ProtocolVersion in the CloudFormation template. For example this worked for me:
