clank-host

Overview ¶

clank-host is the Host plane binary. It owns the BackendManagers and SessionBackends and serves the host HTTP API on either a Unix socket (default for laptop hubs) or a TCP listener (for cloud sandboxes / in-process LocalLauncher tests).

In production it is spawned as a child process by clankd (the Hub). clankd connects via internal/host/client and routes every HUB-tagged operation through the wire.

Usage:

clank-host --socket /path/to/host.sock
clank-host --listen tcp://127.0.0.1:0    # auto-pick port

On startup prints "listening on <addr>" — parents that picked port 0 read this to discover the bound address.

On SIGINT/SIGTERM the server shuts down gracefully and host.Service stops every registered backend.
