      .Building multi-architecture images is fully supported

      The `podman farm build` command that creates multi-architecture container images is now fully supported.

      A farm is a group of machines that have a unix Podman socket running in them. The nodes in the farm can have different machines of various architectures. The `podman farm build` command is faster than the `podman build --arch --platform` command.

      You can use `podman farm build` to perform the following actions:

      * Build an image on all nodes in a farm.
      * Bundle an image on all nodes in a farm up into a manifest list.
      * Execute the `podman build` command on all the farm nodes.
      * Push the images to the registry specified by using the `--tag` option.
      * Locally create a manifest list.
      * Push the manifest list to the registry.

      The manifest list contains one image per native architecture type present in the farm.

      Description

      In some environments, developers need to be able to produce the same container image for multiple CPU architectures. We want to enable developers with access to hardware of various architectures to be able to take advantage of podman's remoting capabilities to create multi-arch ready builds on that hardware in an easy to use way. For RHEL 8.10 and RHEL 9.4 (Podman v4.9), this will be a Tech Preview Feature in RHEL.

       

      As this feature was completed as a Tech Preview in RHEL 8.10/9.4, the work for this feature will mostly consist of adjusting the RHEL documentation to show it is now GA, and to also possibly add a release note.  For QE, it will just be a test to make sure the multi-arch build functionality is still working.

      Requirements

      Have one podman environment be able to hand off builds for other architectures to systems connected via podman system connections. Once connections are properly established, it should be a single command to trigger builds on all enabled architectures.
