The AWS CDK lets you define cloud infrastructure in a real language instead of hand-writing CloudFormation. Until now the choices have been TypeScript, Python, Java, Go and C#, never Ruby. There’s now a working implementation of Ruby support.

It covers the whole of aws-cdk-lib and passes the standard jsii compliance suite. The work is tracked here:

• RFC to make Ruby an official CDK language: https://github.com/aws/aws-cdk-rfcs/pull/939
• Implementation tracking issue: https://github.com/aws/jsii/issues/5129
• The long-standing request this addresses: https://github.com/aws/jsii/issues/3923

If Ruby CDK support is something you’d use, a comment on the RFC with your use case helps more than anything. Prerelease gems are available for anyone who wants to try it and report back; ask on the tracking issue.
