clj-systemd

Basic interface to systemd in Clojure via dbus. For now only basic service and timer functions are implemented.

Usage

With danielsz.system or com.stuartsierra.component

(:require (...)
          [clj-systemd.component :refer [new-systemd]
          [clj-systemd.manager :as manager]])

(defsystem my-system
           (...)
           :systemd (new-systemd :instance-type :system))

(manager/get-service (:systemd system) "my-service.service")

Standalone

(:require (...)
          [clj-systemd.systemd :as systemd]
          [clj-systemd.manager :as manager])
 
(let [systemd (systemd/get-systemd :system)
      manager (-> (systemd/get-systemd :system)
                  (manager/get-manager)]
  (...)
  ;; Clean up after, this will disconnect all :system managers
  ;; as `manager` is implemented as singleton in Java
  (manager/disconnect :system)
