Expected behavior
A clear and concise description of what you expected to happen.

kyverno CLI installed and working in my MacBook Air M1.

[chipzoller]

plugin "kyverno" does not offer installation for this platform

Kyverno CLI is not currently built for Apple silicon.

[scraly]

The problem is that when an user/a developer follow the official procedure, he have this error message.
On the official documentation I haven't found any relevant message about "Kyverno CLI is not currently built for Apple silicon." 🙂

However, by following the build from binaries procedure, I was able to install it on my MacBook M1.

So is it possible to allow the possibility to M1 users to install the kyverno plugin or add a message on the website?

Thanks

[scraly]

I've just saw commits that add arm64 on GoReleaser and Krew configuration files 👍
So hope in the next release kyverno plugin will be available for M1, is it right?

Thx

@scraly that is correct. This was recently fixed in #3002 which is merged and will be made available in the 1.6 release. I am closing this issue and adding it to the 1.6 tracker :)
