Does nerdctl support manifest command to build multi-arch images?

[gaussye]

What is the problem you're trying to solve

I am going to use nerdctl to replace docker for k8s containerd runtime. I also need to create both arm64 & x86 images for my applications. When i run nerdctl manifest command : nerdctl manifest create xxxx FATA[0000] unknown subcommand "manifest" for "nerdctl"

Describe the solution you'd like

Any command like 'docker manifest'?

HI @gaussye

It's unimplemented . https://github.com/containerd/nerdctl/blob/main/docs/command-reference.md#unimplemented-docker-commands

[gaussye]

hi @yankay thanks. Any plan for the unimplemented docker commands. For now any workaround for it?

[AkihiroSuda]

workaround

nerdctl build --platform=amd64,arm64 --output type=image,name=example.com/foo:latest,push=true .

https://github.com/containerd/nerdctl/blob/v1.6.0/docs/multi-platform.md#build--push

@AkihiroSuda for those of us not building the images, just the manifest, how would that workaround look to create just the manifest and push?

Manifest of what?

[FernandoMiguel]

@AkihiroSuda image manifest, so we can have two arch images linked

Hi,

In some scenarios, we may prefer/need to build images independently for each arch to avoid emulation when building an arch on a different arch (single command is nice but emulation is often not efficient). Then we need to combine these images in a manifest list. The current workaround is more to use manifest-tool, origin of docker manifest commands.

thanks for the link to that amazing tool @jlamande
