Doesn't Kubernetes deduplicate layers by hash? I thought the key to minimizing overhead was standardizing on a limited set of images across everything you'll be running on the same host.

Just from reading HN it seems like Alpine had a brief fad a few years ago but never got much traction.

the underlying container runtime (usually containerd) will dedupe shared layers, but there's a lot of things you don't get to directly control, like third party apps, and the bottleneck when spinning up new nodes is real. Plus, envs where there isn't that much caching, like CI.
