Start HTTP server with aptly REST API. The server can listen to either a port
|

or Unix domain socket. When using a socket, Aptly will fully manage the socket

file. This command also supports taking over from a systemd file descriptors to
|
|
enable systemd socket activation.

$ aptly api serve -listen=:8080

$ aptly api serve -listen=unix:///tmp/aptly.sock
