Make alarm clocker by using combine of systemD, python, and slackbot
Create SystemD service
- The service will start along with your machine and running background process to check clocker
⚡ $ cat Clocker.service
[Unit]
Description=Polling check clocker alarm
Requires=network.target
After=multi-user.target
[Service]
Type=forking
PIDFile=/var/run/clocker_polling.pid
ExecStart=/opt/ops/clocker_polling.sh
StandardOutput=/var/log/clocker-alarm.log
StandardError=/var/log/clocker-alarm.error
Restart=on-failure
RestartSec=5s
[Install]
WantedBy=multi-user.target
Create wrapper script to start service
⚡ $ cat /opt/ops/clocker_polling.sh
#!/bin/bash
rm -f /var/run/clocker_polling.pid
python3 /opt/ops/clocker.py &
echo $! > /var/run/clocker_polling.pid
⚡ $ sudo chmod +x /opt/ops/clocker_polling.sh
Python script to run process
⚡ $ cat /opt/ops/clocker.py
