Docker image update checker with discord/gotify webhook integration

🇫🇷 Version Française 🇫🇷

A little script that will notify you on your discord server, here is what you can expect for discord :

And for gotify :

For help recovering your discord webhook url see below :

If like me you would rather use gotify, see here to recover the token that also needs to be put at the 3rd line of the script.

• Installation

  sudo apt install jq curl wget
  cd && mkdir image_checker && cd image_checker
  wget https://raw.githubusercontent.com/methatronc/checker/main/checker.sh
  chmod +x checker.sh
  su [the user that will execute this cron and that MUST NOT have any special privileges since we are retrieving external data]
  crontab -e
  

And add the following line for instance :

0 5 * * * /home/[your_username]/image_checker/checker.sh > /home/[your_username]/image_checker/cron.log 2>&1

• Now you will have your daily report at 5am on your discord server if any image currently used on the host executing the cron gets updated.

• Do not forget to specify the gotify/discord token at the 3rd line or else nothing will happen.

• If you have anything to add please do, some images might need other particular treatment.
