docker{,-rootful}.yaml: Enable the containerd image store by default

[norio-nomura]

To support building multi-platform images.
Use --set .param.containerdSnapshotter=false flag to disable it.

#3858 (comment)

https://docs.docker.com/desktop/features/containerd/

The containerd image store is enabled by default in Docker Desktop version 4.34 and later, but only for clean installs or if you perform a factory reset.

4.34 was released on 2024-08-29
https://docs.docker.com/desktop/release-notes/#4340

edit: remove "To support...", and "Use ..."

Thanks

To support building multi-platform images.

For this purpose, using containerd image store is not necessary, as it is supported by buildx

I don't think so, how would it even work? AFAIK the "classic" image store doesn't support multi-platform manifests.

And buildx refuse to build for me:

❯ docker buildx build --platform linux/arm/v7,linux/arm64/v8,linux/amd64 --tag multiarch .
[+] Building 0.0s (0/0)                                                                                    docker:lima-docker
ERROR: failed to build: Multi-platform build is not supported for the docker driver.
Switch to a different driver, or turn on the containerd image store, and try again.

Thanks, LGTM

You can't store multi-platform manifests, but you can still build and push them with a custom buildx instance.
(docker buildx create --use and docker buildx build --push)
