This has been discussed in #33664

using :latest tag IMO is not the best practice as it's hard to track what image is really in use in your pod. I think tagging images by versions or using the digests is strictly better than reusing the same tag. Is it really such a hassle to do that?

The recommended way is to not use image tag :latest when using declarative deployment with kubectl apply.
