Effectively, this is an ability to take an image already pulled to the system, and automatically mount it into one or more containers defined in Kubernetes YAML accepted by `podman play`. Requirements: - The image must already exist in storage. - The image must have at least 1 volume directive. - The path given by the volume directive will be mounted from the image into the container. For example, an image with a volume at `/test/test_dir` will have `/test/test_dir` in the image mounted to `/test/test_dir` in the container. - Multiple images can be specified. If multiple images have a volume at a specific path, the last image specified trumps. - The images are always mounted read-only. - Images to mount are defined in the annotation "io.podman.annotations.kube.image.automount/$ctrname" as a semicolon-separated list. They are mounted into a single container in the pod, not the whole pod. As we're using a nonstandard annotation, this is Podman only, any Kubernetes install will just ignore this. Underneath, this compiles down to an image volume (`podman run --mount type=image,...`) with subpaths to specify what bits we want to mount into the container.
