Docker Image pack:base does not include shell

[kaiomatico]

Summary

Running the command docker run --rm --it --entrypoint sh buildpacksio/pack:0.33.2-base works fine, but docker run --rm --it --entrypoint sh buildpacksio/pack:base results in the error that sh could not be found in $PATH

---

Reproduction

Steps

See above

Current behavior

sh could not be found in $PATH on the base image without version tag

Expected behavior

sh should be included in the base image tag just like it is on the 0.33.2-base image tag

Environment

pack info

docker info

Docker 24.0.5 on Linux

I think the problem is in this line

We expect to retag the base, jammy image to :base but we are using an image reference without the ${{ matrix.suffix }} and we ended up copying the tiny image (based on distroless)

I am relatively new to this repository, and although this issue does not have a 'good first issue' label, may I still try to tackle it?

I understand that testing a fix for this issue, especially within a GitHub Action job, is not a simple task. For now, I'm thinking of creating a repository with the necessary files to reproduce it and checking the changes to eliminate the problem in the repo.

Is there any recommendation for the testing procedure?

@hhiroshell we would love to have your help with this!

For testing stuff out with GitHub Actions (especially jobs that only run after a release) sometimes building out a fork is the only way to do it. But, you might remove the jobs that are irrelevant to what you are testing or require cumbersome setup (see here what we do for the lifecycle including stripping out all tests). Let us know if you run into any issues with it, so that we can unblock you if we can.

@natalieparellano Thank you so much for such helpful information. I'll give it a try to do the same!

@natalieparellano
I encountered some issues with the tools/test-fork.sh script in the lifecycle repository when I tried to run it, so I created a PR to fix them. Could you please review it?

[hhiroshell]

@natalieparellano
I created a PR adding a script for the same purpose as the tools/test-fork.sh in the lifecycle repository.

I apologize for the repeated requests, but could you please review it?

@natalieparellano
Thank you for reviewing the series of PRs.

It was also beneficial to study the release process for my understanding.
