"""Run a local Linux VM from a trycua OCI registry image with the Cua Sandbox SDK.

async with Sandbox.ephemeral(

Image.from_registry("ghcr.io/trycua/cua-xfce:latest"),

|
|
|
|
TartRuntime uses Apple's Virtualization.framework (via Tart CLI) to run OCI VM images.
|
|
Image.from_registry() is required — TartRuntime only works with OCI registry references.
|
|
|
|
Contrast:
|
|
Image.linux("ubuntu", "24.04", kind="vm") + local=True -> QEMU VM, managed Cua image
|
|
Image.from_registry("ghcr.io/trycua/...") + local=True + TartRuntime -> Tart VM, OCI registry image (macOS only)
|
|
Image.from_registry("ghcr.io/trycua/...") + local=False -> Cua cloud VM
