subprocess

Documentation

Overview

Command subprocess is the canonical parent→child spec handoff: the parent process mints a tunnel spec and passes it to a spawned child through the LIBTUNNEL_SPEC environment variable; the child provides the listener, connects the tunnel, and serves; the parent then requests the child's public URL.

It needs network access (it mints a tunnel from api.trycloudflare.com); the e2e harness only runs it when LIBTUNNEL_E2E_LIVE=1.
