What happens if you replace the version with a version strategy?

Dear lord, of course. I changed the issue, PR and commit to reflect this.

Whilst I'd prefer more output in the testing section - the minimal output to provide is created by running the provided command - this change looks reasonable to me.

@alexellis do you want to take this, or prefer that it be addressed as an aside in a future change?

@toredash I see a 404 on the windows side of things despite the asset being available in the releases.

Can we get the template updated to fix windows and accommodate the arm64 variant?

There was a reason why it was done this way - I think because semver had issues locating the proper release - since the kustomize repo was releasing multiple releases all with different suffixes and a version strategy could pick the wrong one depending on what was released last.

I assume that is still the case.

I would advise checking back and seeing.

[rgee0]

Its a good spot Alex.

Although releases/latest resolves to: https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize/v5.6.0 and the version strategy approach uses version := loc[strings.LastIndex(loc, "/")+1:] the fact it works looks to be more luck than judgment.

The irregular approach to tagging that is used on kustomize appears to be accommodated by the arkade approach to resolving the version, but https://github.com/kubernetes-sigs/kustomize/releases show you where the potential dragons are.

Its particularly easy to fall into the trap since the version strategy approach was introduced 8 months ago while the last time the kustomize version was updated was 2 years ago, leading you to believe that the previous problem may have been alleviated by more recent changes, however, I'm of the view that if one of the other tag prefixes found itself being provided by latest/releases then we'd find a version like v0.19.0 which would then fail to be found when looking for kustomize at that version.

Thank you for your contribution. unfortunately, one or more of your commits are missing the required "Signed-off-by:" statement. Signing off is part of the Developer Certificate of Origin (DCO) which is used by this project.

Read the DCO and project contributing guide carefully, and amend your commits using the git CLI. Note that this does not require any cryptography, keys or special steps to be taken.

💡 Shall we fix this?

This will only take a few moments.

First, clone your fork and checkout this branch using the git CLI.

Next, set up your real name and email address:

git config --global user.name "Your Full Name"
git config --global user.email "[email protected]"

Finally, run one of these commands to add the "Signed-off-by" line to your commits.

If you only have one commit so far then run: git commit --amend --signoff and then git push --force.
If you have multiple commits, watch this video.

Check that the message has been added properly by running "git log".

@rgee0 Updated the binary template as requested, and the test tool is expanded to cover the arm cases.
