sozu, a HTTP proxy
This project wraps the
sozu_lib library to make it scalable and dynamically
configured. Each single threaded event loop is started in a worker process that
receives configuration commands through anonymous unix sockets.
This executable requires a configuration file in the TOML format, that describes the worker types and numbers, along with global information. This file can describe the applications handled by the proxy, but it is more recommended to use the command unix socket, through which the proxy listens for orders or configuration changes. The path of that unix socket is set in the configuration file.
Command socket message format
The proxy receives order through a unix socket. The path to this unix socket can
be defined by the
command_socket option in the TOML configuration file.
The messages are sent as JSON messages, separated by the 0 byte.
Their format is defined in
../command/README.md. Additionally, the
sozu_command_lib crate in
../command already provides the necessary
structures, serialization and deserialization code to communicate with
the command socket.
