Go bindings to systemd. The project has three packages:
Go docs for the entire project are here:
http://godoc.org/github.com/coreos/go-systemd
An example HTTP server using socket activation can be quickly setup by following this README on a Linux machine running systemd:
https://github.com/coreos/go-systemd/tree/master/examples/activation/httpserver
Using this package you can submit journal entries directly to systemd's journal taking advantage of features like indexed key/value pairs for each log entry.
The D-Bus API lets you start, stop and introspect systemd units. The API docs are here:
http://godoc.org/github.com/coreos/go-systemd/dbus
Create /etc/dbus-1/system-local.conf
that looks like this:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <policy user="root"> <allow eavesdrop="true"/> <allow eavesdrop="true" send_destination="*"/> </policy> </busconfig>
