try something like `linux/arm/v7,linux/arm64/v8,linux/amd64` for the  `platform` argument: <https://www.pulumi.com/registry/packages/docker/api-docs/image/#platform_nodejs>

I tried, but this is rejected by the regex :
```Error response from daemon: "v8,linux" is an invalid component of "linux/arm64/v8,linux/amd64": platform specifier component must match "^[A-Za-z0-9_-]+$": invalid argument```

from <https://github.com/pulumi/pulumi-docker/issues/296> I'm guessing that this isn't supported at the moment

No, that should be supported. What version of the provider are you using?

As a workaround, you can definitely create 2 single-platform images and combine them with `docker manifest`, which you could call using the Pulumi Command provider.

It might just be that the validation is too strict.

I know it's not ideal, but this example should give you an idea of the syntax: <https://github.com/pulumi/pulumi-docker/issues/296>

I have the manifest creation working using `local.Command`as you suggested. That'll work for now :slightly_smiling_face: thanks.

Can you also file an issue here? The intent is definitely that multi-arch build should work. It's either a bug, or it's not sufficiently documented. In either case, Pulumi would like make this smooth: <https://github.com/pulumi/pulumi-docker/issues>

Ugh. I see that was closed as dupe. That's my fault as I am aware of the referenced issue. I just wasn't sure it was the same issue.

In other news, I just realized that I sent you the wrong link for an example of how to use `docker manifest`. This is what I meant to link you to: <https://github.com/pulumi/pulumi-docker-containers/blob/main/.github/workflows/release.yml#L198-L204>
