Add Serverless API Template for Ruby Runtimes (3.2 and 3.3)

[toydestroyer]

Description of changes:

Adding Serverless API template for Ruby runtimes (both 3.2 and 3.3).

This template implements the following CRUD functions:

• CreateItemFunction with DynamoDBCrudPolicy, exposed through the POST / endpoint.
• GetAllItemsFunction and GetItemByIdFunction with DynamoDBReadPolicy, exposed through the GET / and GET /{id} endpoints, respectively.
• UpdateItemFunction with DynamoDBCrudPolicy, exposed through the PUT /{id} endpoint.
• DeleteItemFunction with DynamoDBCrudPolicy, exposed through the DELETE /{id} endpoint.

Each function is tested with minitest and includes corresponding JSON events in the events/ directory for local invocation.

P.S. I took the liberty of moving the Runtime, Architectures, MemorySize, and Timeout directives to the Globals section. Please let me know if you prefer these to be explicitly defined for each function, as they are in the nodejs20.x/web template.

Thanks for creating this PR! It looks fine in general, no issues from me with using the Globals section for all those properties.

Could you add the templates into our testing framework? The logic itself won't be tested since this requires AWS credentials, but we just want to make sure that its included in the CI checks.

There are two locations:

• https://github.com/aws/aws-sam-cli-app-templates/blob/master/tests/integration/unit_test/test_unit_test_ruby3_2.py
• https://github.com/aws/aws-sam-cli-app-templates/blob/master/tests/integration/unit_test/test_unit_test_ruby3_3.py

These two files are pretty much identical. Basically, these two test files will run the Ruby test files inside of the new template file.

While that is happening, I can validate the behaviour of the template itself.

Done in 1e362fd. I wasn’t sure which name to include in the TODO comment, so I left it blank.

Actually, does this mean that ruby3.3 is now supported by cfn-lint?

https://github.com/aws-cloudformation/cfn-lint/blob/4a57bc9f626992e3d9a67fc68f995d669279eac8/src/cfnlint/data/schemas/providers/us_east_1/aws-lambda-function.json#L429

Should I remove should_test_lint = False altogether?

[lucashuy]

Yup, it looks like sam validate --lint works fine with Ruby 3.3 functions, so we should remove that line in the tests now.

[toydestroyer]

Removed 👍

Hm, I see that test failed because it couldn't find aws-sdk-dynamodb, but I'm not sure if b026283 will help

[toydestroyer]

I’ve checked the CI on my repo, and yes, b026283 does help! @lucashuy, could you please take another look at this PR?

Thanks for your contribution.

Could you please also add tests in the files below:

• https://github.com/aws/aws-sam-cli-app-templates/blob/master/tests/integration/build_invoke/ruby/test_ruby_3_2.py
• https://github.com/aws/aws-sam-cli-app-templates/blob/master/tests/integration/build_invoke/ruby/test_ruby_3_3.py

@hawflau thanks for the review!

Added build_invoke tests in 6b2b4c0. I had to introduce a new BuildInvoke class because I have more JSON events than node/dotnet versions.

LGTM. Thanks for your contribution!
