Defining the following ensures that even after system restart your service is restarted
# /lib/systemd/system/torrent_top_10.service [Unit] Description=Run top 10 torrent service # Wait until the network is available After=network.target [Service] # Run the binary that was generated by mix release ExecStart=/home/pi/redacted-discord-bot/redacted-discord-bot-main/_build/prod/rel/app/bin/app start User=pi RemainAfterExit=yes [Install] WantedBy=multi-user.target
# Before doing this make sure your environment has the necessary variables that are accessible. I recommend using direnv to manage this MIX_ENV=prod mix release
# Reload the daemon (pronounce it with me de-mon) so it picks up on the .service file sudo systemctl daemon-reload # Start your new service sudo systemctl start torrent_top_10 # Check the status of the service to make sure it's healthy sudo systemctl status torrent_top_10 # Here's some example output ● torrent_top_10.service - Run top 10 torrent service Loaded: loaded (/lib/systemd/system/torrent_top_10.service; e Active: active (running) since Sun 2021-12-12 18:31:44 MST; 5 Main PID: 18293 (beam.smp) Tasks: 27 (limit: 4915) CGroup: /system.slice/torrent_top_10.service ├─18293 /home/pi/redacted-discord-bot/redacted-discor ├─18334 erl_child_setup 1024 ├─18370 inet_gethost 4 └─18371 inet_gethost 4
I'm curious to see how the
daemon option would work and if that would be better than passing
start to the mix release.
