Publish Homebrew bottles for this tap

[mislav]

I've taken a stab at publishing Homebrew bottles for formula in this repo: rbenv/tap/[email protected] and rbenv/tap/[email protected]

On macOS Sequoia 15 arm64, running brew install for any of these formulae should install "bottles" from this organization, which are basically pre-built packages for a certain OS & architecture.

What follows are some of my notes on how this is done.

Important

If you were getting errors such as these in the last 24 hours:

Error: [email protected]: Failed to download resource "[email protected]"
Download failed: https://ghcr.io/v2/rbenv/tap/openssl/1.1/blobs/sha256:***

that was because I've messed things up in the process, but it should be fixed now. If you're still getting those errors consistently, please comment here or open a new issue. 🙏

How I did it

First off, my local environment:

export HOMEBREW_DEVELOPER=1
export HOMEBREW_NO_AUTO_UPDATE=1
export HOMEBREW_NO_INSTALL_FROM_API=1
export HOMEBREW_NO_INSTALL_CLEANUP=1
export HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK=1
export HOMEBREW_GITHUB_PACKAGES_USER="mislav"
export HOMEBREW_GITHUB_PACKAGES_TOKEN="***"

The steps:

1. brew uninstall [email protected] [email protected]
2. brew install --build-bottle rbenv/tap/[email protected]
3. brew install --build-bottle rbenv/tap/[email protected]
4. brew bottle --json rbenv/tap/[email protected] --root-url="https://ghcr.io/v2/rbenv/tap"
5. brew bottle --json rbenv/tap/[email protected] --root-url="https://ghcr.io/v2/rbenv/tap"
6. brew pr-upload --root-url="https://ghcr.io/v2/rbenv/tap"
7. Manually edit the bottle ... section in formula files to declare root_url "https://ghcr.io/v2/rbenv/tap"
8. git push

Notes:

• brew bottle produces a *.tar.gz package and a *.bottle.json
• brew pr-upload takes all *.bottle.json files, edits the local formulae to add the bottle ... section to them, and uploads the tarballs to GitHub Packages using HOMEBREW_GITHUB_PACKAGES_TOKEN

TODO

• publish bottles for machines other than macOS Sequoia arm64
• make a reusable GitHub Action for this
• figure out how to run this in CI after formula updates
• ⚠️ figure out the problem of GitHub Packages being published as private by default https://docs.github.com/en/packages/learn-github-packages/configuring-a-packages-access-control-and-visibility
• ⁉️ find out what sha256 values in the "bottle" section mean and how to verify that the corresponding containers are actually available from ghcr.io
