Version 1

workshop: Writing services the systemd way

Harnessing systemd's high-level functionality to make services simpler

Pantheon fist color2

Historically, services have handled forking, privilege dropping, logging, monitoring, and sandboxing either on their own, using a language-specific framework, or binaries like daemontools. With systemd, this is no longer necessary. In this workshop, we'll create a service from scratch that has systemd handle everything except the core functionality.

In this workshop, we will build a basic application (framework/language to be determined) that uses:


  • Socket activation

  • The journal

  • Type=notify for state tracking

  • Watchdog for availability monitoring

  • Advanced unit configuration for sandboxing/isolation

We will primarily be using C and autotools, but the concepts are the same for most languages. Don't worry if you're not fluent in C or autotools; we'll start from scratch.
