SystemdDaemon

sd-daemon bindings for ruby!

Installation

We need to have libsystemd-dev and libsystemd0 installed in order to compile systemd-daemon, once those are in place add the following line to your application's Gemfile:

gem 'systemd-daemon'

And then execute:

$ bundle

Or install it yourself as:

$ gem install systemd-daemon

Usage

Ready

SystemdDaemon::Notify.ready

Notify with fds

Sending one fd

read_fd, write_fd = IO.pipe
state = {
  FDSTORE: 1,
  FDNAME: pid
}
SystemdDaemon::Notify.notify_with_fds(0, state, read_fd.to_i)

Sending an array of fds

read_fd1, write_fd1 = IO.pipe
read_fd2, write_fd2 = IO.pipe

fds = [read_fd1.to_i, read_fd2.to_i]
state = {
  FDSTORE: 1,
  FDNAME: "testgroup"
}

SystemdDaemon::Notify.notify_with_fds(0, state, fds)

Listen fds with names

fds_hash = SystemdDaemon::Notify.listen_fds_with_names
# fds_hash = {"listening_socket_a"=>3, "listening_socket_b"=>4, "listening_socket_c"=>5}
