I want to implement this function. How should I prepare? Are there any detailed reference steps?

@cubxxw thank you for your interest! This issue is actually intended for the Google Summer of Code mentorship project (I've marked it blocked for now). If you're just interested in getting involved with pack, I'd suggest checking out one of our "good first issues". Or, if you are interested in applying to GSoC, here is some additional background about this issue that might be helpful:

Dockerfiles in the CNB spec is a relatively new and rather niche feature, but it unlocks a lot of use cases. Some prior knowledge of buildpacks will be useful in the implementation. See the tutorial here: https://buildpacks.io/docs/extension-author-guide/create-extension/ and the RFC here: https://github.com/buildpacks/rfcs/blob/main/text/0105-dockerfiles.md

Hey @natalieparellano, I am Samyak Jain, a final year student pursuing B.Tech in Mathematics and Computing from Delhi Technological University. I find this project really interesting for GSOC'23. Could you help me out in getting started?

Hey @natalieparellano , I am Nandini, a second year student pursuing B.E in Information and Technology and I am interested in this project for GSOC 2023. I want to work on this. I am familiar with the technology that is required for this project.

Hi @natalieparellano, I am a master from Zhejiang University, familiar with cloud native, kubernetes, docker and Go, I am also interested in this project and hope to participate in the community through this issue.

Hi @natalieparellano , currently I am doing my research on cloud securtiy (specifically for conatainer security) , let me know if I can use my skill in contributing this issue.

for now I am going through the https://github.com/buildpacks/rfcs/blob/main/text/0105-dockerfiles.md
Please share if something else requires to be done beforehand

Dear team @natalieparellano , I am a master student from Shanghai Jiao Tong Unversity and TUM. I have great interests in this project. Do you still accept student to apply GSoC with this project? Should we solve the good first issue and then we can apply? Thank you very much.

Closing this issue as our findings from #1791 showed that the added complexity from this change may not be worth the performance benefit
