LGTM

Thanks @relu 🏅

Hey 👋 I believe this will trigger #1201 . We should warn somewhere that an upgrade will trigger a rollout of every canary.

As a solution for the previous issue could we change the hash function so that it doesn't change during a lib upgrade? Thanks

[stefanprodan]

The serialisation seems to be same, otherwise the CI would fail in this PR.

[joaosilva15]

Can you point me to the test that is doing it for the deployment spec? I could not find it and doing local tests we did end up with differences using the lib for k8s 1.27 vs 1.30

[relu]

There is one important addition from K8s 1.28 that could cause the above-mentioned issue: sidecar container support via the new .initContainers[].restartPolicy field. This is the reason that prompted me to submit the PR in the first place 😄

I've updated the kind node version used in e2e tests. Pinned to v1.29.2 as that's the latest stable version available.

lgtm! thanks a lot @relu, i tried to get this done a couple of times but couldn't get it over the finish line, much obliged 🙇

[stefanprodan]

@relu there is a new kind release that supports 1.30, please update the workflow to https://github.com/kubernetes-sigs/kind/releases/tag/v0.23.0
