It may be used to bi-directionally + forward traffic from a local listening socket to a local or remote + destination socket. + + One use of this tool is to provide socket activation support + for services that do not natively support socket activation. On + behalf of the service to activate, the proxy inherits the socket + from systemd, accepts each client connection, opens a connection + to a configured server for each client, and then bidirectionally + forwards data between the two. + This utility's behavior is similar to + socat1. + The main differences for systemd-socket-proxyd + are support for socket activation with + Accept=no and an event-driven + design that scales better with the number of + connections. + + + Options + The following options are understood: + + + + + + + + Sets the maximum number of simultaneous connections, defaults to 256. + If the limit of concurrent connections is reached further connections will be refused. + + + + + + + Sets the time before exiting when there are no connections, defaults to + infinity. Takes a unit-less value in seconds, or a time span value such + as 5min 20s. + + + + + + + Exit status + On success, 0 is returned, a non-zero failure + code otherwise. + + + Examples + + Simple Example + Use two services with a dependency and no namespace + isolation. + + proxy-to-nginx.socket + + + + proxy-to-nginx.service + + + + nginx.conf + + + + + + Enabling the proxy + + + If nginx.service has StopWhenUnneeded= set, then + passing to systemd-socket-proxyd allows + both services to stop during idle periods. + + + Namespace Example + Similar as above, but runs the socket proxy and the main + service in the same private namespace, assuming that + nginx.service has + PrivateTmp= and + PrivateNetwork= set, too. + + proxy-to-nginx.socket + + + + proxy-to-nginx.service + + + + nginx.conf + + + + Enabling the proxy + + + + + + See Also + + systemd1, + systemd.socket5, + systemd.service5, + systemctl1, + socat1, + nginx1, + curl1 + + + -- cgit v1.2.3
