Sozu Command API
The Sozu Command API provides programmatic control of the Sōzu HTTP reverse proxy at runtime. External tools communicate with the Sozu main process through a secure Unix socket using a protobuf-based binary protocol (IPC). The sozu-command-lib crate ships the protobuf schema, configuration parser, replicated state, channels, and file descriptor passing helpers. This enables dynamic cluster configuration, certificate management, and backend routing changes without restarts.
