Using gRPC Swift for Container Agents in Apple Containerization
summary
Apple Containerization uses a VM-backed container runtime where a VM init agent (VMD) hosts a gRPC server to orchestrate runtime setup: gRPC over a VZ virtio socket carries create/start/process RPCs, mount/unmount for Rosetta x86 emulation, and netlink-based IP/configuration. The stack moves from Swift+Go to a Swift-only runtime stack, uses protos evolved v1→v2→v3 for safe versioning, and the system is implemented and reported to work with quick container startup and cross-architecture process lifecycle control.
