Unable to build multi-arch via Podman CURL / API.

[cdrage]

Issue Description

When trying to pass in --platform equivalent within the API, I am getting this parsing error:

{"cause":"invalid argument","message":"failed to parse query parameter 'platform': \"linux/arm64,linux/amd64\": invalid platform syntax for --platform=\"linux/arm64,linux/amd64\": \"arm64,linux\" is an invalid component of \"linux/arm64,linux/amd64\": platform specifier component must match \"^[A-Za-z0-9_-]+$\": invalid argument","response":400}

Steps to reproduce the issue

Steps to reproduce the issue

1. Package any Containerfile (tar -czf context.tar.gz -C dir .)
2. Use the below CURL command:

curl --unix-socket ~/.local/share/containers/podman/machine/applehv/podman.sock -X POST \
     -H "Content-Type: application/tar" \
     -H "Content-Encoding: gzip" \
     --data-binary "@context.tar.gz" \
     "http://d/v4.0.0/libpod/build?platform=linux/arm64,linux/amd64&t=quay.io/mytestcontainer"

{"cause":"invalid argument","message":"failed to parse query parameter 'platform': \"linux/arm64,linux/amd64\": invalid platform syntax for --platform=\"linux/arm64,linux/amd64\": \"arm64,linux\" is an invalid component of \"linux/arm64,linux/amd64\": platform specifier component must match \"^[A-Za-z0-9_-]+$\": invalid argument","response":400}

Describe the results you received

Getting a platform error (see above).

Describe the results you expected

Passing, similar to:

podman build --platform="linux/arm64,linux/amd64" -t mytestcontainer .

[cdrage]

Closing this as this is intentional in the API and not a bug.

To create multi-platform / multi-arch, it's creating a manifest, then building, then adding it to manifest.

[nalind]

It should work, by setting a "manifest" parameter and passing two "platform" parameters.

[nalind]

(Whether needing to set "manifest" rather than "t" and needing to supply elements of the platforms list in separate "platform" arguments is a bug is not something I'm enough of an expert to weigh in on.)

[mheon]

I'll reopen given Nalin's comments

A friendly reminder that this issue had no activity for 30 days.

[Luap99]

The docker API seems to accept comma separated values so we must match this in the API.
