tausolutionsmx/cfn-lint repository overview

⁠cfn-lint

Containerized cfn-lint⁠ — validates AWS CloudFormation templates against the AWS resource specification, catching invalid resource properties, bad intrinsic function usage (Ref, Fn::GetAtt, Fn::Sub, Fn::Join), malformed YAML/JSON, and region-specific availability issues before you deploy.

Packaged as an image so local runs and CI use the identical linter version — no Python toolchain or virtualenv needed on the host.

⁠Usage

Lint a single template:

docker run --rm -v "$PWD":/work -w /work <your-namespace>/cfn-lint:latest template.yaml
