pls update the yamls in test/testdata

Heya @hzxuzhonghu! Thanks for this! Have we validated that the resultant image from this change, and the manifests all work?

Understood that this is a massive PR, but I think with such a large change I just want to make sure we aren't breaking ourselves

Have we validated that the resultant image from this change, and the manifests all work?

Good point, i do think we need to update the image to support v1alpha2. So who can trigger that?

[ahg-g]

Can you please update the yamls in the repo to point to v1alpha2? I will run the e2e test once you do.

[ahg-g]

I updated the yamls in #420 and test this PR with the one that updates the yamls, works as expected
