Decrease installation size

Is this feature request related to a new rule or cfn-lint capabilities?

No response

Describe the feature you’d like to request

I tried running cfn-lint with pre-commit on its CI service, pre-commit.ci. I got this error:

clone of https://github.com/aws-cloudformation/cfn-lint@v0.66.1 exceeds tier max size 100MiB: 142.1MiB

Oh no.

Describe the solution you’d like

I’d like the repo to be smaller, similar to the motivations in #2368.

The src/cfnlint/data/CloudSpecs directory is huge, as I think you’re aware. Gzipping it takes it from 141MB to 8.5MB. The decompress time on read is probably worth it. Also most users will only need the files from a couple of regions.

This will also save developer machines’ disk space, where there may be several cfn-lint versions installed, between several projects.

Additional context

I suggested similar to botocore: https://github.com/boto/botocore/issues/2365

Is this something that you’d be interested in working on?

Nice work, thank you!

Okay, thanks for the update. To workaround the issue, I made a fork with many of the specs that my project doesn’t need removed: https://github.com/ev-energy/cfn-lint/commit/aa45e3a2a161f1fcdc35ce1bceeb652009394e17
