@jjbustamante Hope you had a good new years! I was wondering if you could take a look at this PR? I am trying to upgrade a bunch of buildpack libraries to the newer docker version. As a followup to this PR I plan to create a new pull request to upgrade docker for buildpacks/pack.

Hi @alphanota

Thanks for this PR! Why should we change the upstream kaniko dependency to the osscontainertools repo?. We moved to chainguard based on their blog post and they are releasing patches.

Could you provide more information about the osscontainertool organization?

Hey @jjbustamante,
I’m Martin, core maintainer of osscontainertools. Unlike the Chainguard fork, our community fork actively evolves kaniko with bug fixes, performance and usability improvements. Our goal is bring kaniko to feature parity with buildkit. We are currently a team of 5 maintainers working on the project.
Happy to help with any questions.
