Publish mac darwin compatible binaries

What steps did you take:

probably an easy fix, just need to support arm64 i think in the brew publication process?

GOOS=darwin GOARCH=arm64 go build -o  ...

brew install ytt kbld kapp imgpkg kwt vendir

==> Downloading from https://github-releases.githubusercontent.com/173207060/7e47b79b-a02d-48f2-87b5-604

What happened:
looks like the 64 intel brew is the only one supported?

Thanks for surfacing this. I think you're right and that all we'd have to do is update our homebrew formulas. Ideally, we'll automate this so it doesn't add ongoing toil. I created a couple of issues in that repo to address this work. For now, we can keep this issue open to increase visibility on this.

Also, the install script currently selects the AMD64-targeted version of our tools...

https://github.com/vmware-tanzu/carvel/blob/5e8da622826935aded946c4d4f53e38a3695de29/site/static/install.sh#L28-L36

Let's update that script as part of this work as well so that if you install on an M1, you get ARM64 binaries through all install paths.

Added a Apple Silicon-targeted version for our latest release. There is a PR updating our scripts to do this for future releases.

Made a PR to vmware-tanzu/homebrew-carvel updating the formula for kapp.
Looks like vendir needs a similar change.
Homebrew formulas for kbld, imgpkg and kwt seem to not check for amd64-targeted binaries at all, just like the install script. They should be updated once these binaries are available, they are not built as of now (for both Linux and Darwin).

imgpkg and kbld next release will generate a mac arm binary

See the below PRs for details
imgpkg PR
kbld PR

The next time an imgpkg or kbld release occurs, in addition to modifying the homebrew formula and install.sh with the new version and sha, a change to also include the mac arm binary will need to be made (similar to the PR made above by @100mik)

I'm not sure how to best capture this 'one-off' release step.

I'm not sure how to best capture this 'one-off' release step.

@DennisDenuto note the list of issues in the description ... there's one for each tool, respectively... is that a good place to capture the release step?

[DennisDenuto]

Yes I think so. However when a release is being performed (in the future), I think ultimately, the person conducting the release will need to remember to also make additional updates to the homebrew formula and install.sh (which are in separate repos).

brew install vmware-tanzu/carvel/kwt
kwt: The x86_64 architecture is required for this software.
Error: kwt: An unsatisfied requirement failed this build.

[aaronshurley]

Thanks, @vangie. We haven't yet updated kwt's build process but have an issue tracked here: carvel-dev/kwt#28.

I'll drop a mention in our slack channel just so that folks are aware and in case someone has bandwidth to knock this out. As always, PRs are welcome :)
