No caching for dynamically generated Dockerfile

[bayerlse]

Hey there 👋

I'm having following issue:

Actual behavior When dynamically generating a Dockerfile within the deployment process (which is our default behaviour in our deployment pipeline), kaniko doesn't match the cache layer (because of mtime, i guess)

Expected behavior If the dockerfile content is not changed within the generated Dockerfile, cache should be used.

Is there any possibility to be able to cache generated Dockerfiles?

Thanks in advance!
