Use Cloud Control API

[ineffyble]

It should be possible to use the new AWS Cloud Control API, both to simplify the methods used to find resources, and to find resources that aren't currently found (and potentially to make it so that new resource types work without any code changes).

As janky as it is to scrape the API calls from boto3's model, it still seems like the best way to get complete coverage.

In theory Cloud Control is a great idea and a service long overdue from AWS's side. But in practice the resource coverage is incomplete.

The documented resource types that support Cloud Control API today shows that 584 resource types are supported by Cloud Control and 526 of those support the List operation.

CloudFormation's ListTypes API lists today 898 public resource types in the "AWS::" namespace.

aws cloudformation list-types \
--visibility PUBLIC \
--type RESOURCE \
--query 'TypeSummaries[?starts_with(TypeName, `AWS::`)].[TypeName]' \
--output text \
| wc -l

And of course there are many more resource types that CloudFormation still does not support. I'm not even sure where to get an authoritative list for those.

Well, this is interesting! It would definitely be easier for the types known to CloudFormation, but given that some "legacy" types will probably never be supported I guess the basic heuristic will be required for quite some time.

I'll leave this open as an enhancement in case someone wants to work on this - it does have the possibility to remove some of the edge cases.

Cloud Control still doesn't even support EC2 instances ☹️

[iainelder]

aws-list-resources discovers resources that are currently supported by the AWS Cloud Control API and offer support for the List operation. It is further restricted to those resources where the List operation does not expect any additional parameters.

@JohannesEbke, since that implementation exists, I don't think you need to change aws_list_all use Cloud Control.

@ineffyble, today Cloud Control still doesn't support EC2 instances :-)
