Question:
I want to install a systemd service from a Jinja2 template. How do I do this?
Do I have to use copy module to copy the file to /lib/systemd/system and then use systemd module to enable it?
Is there a better way?
Answer:
I use the template module to install the .service file into the /etc/systemd/system. /lib/systemd/system should be reserved for packages bundled with the OS itself, and third party services should be defined in /etc/systemd/system.
With ansible’s systemd module I’d start the service with daemon_reload=yes.
Prior to Ansible 2.2: I do a systemctl daemon-reload afterward (can use an ansible handler for this if appropriate) to prod systemd to pick up the new file.
