log-to-telegram Docker

A docker container for reading growing log files and sending notifications via the telegram API based on items in a trigger list. Inspired by JVCubed/log-to-telegram. I mostly use it to send Pi-Hole events to Telegram.

Setup Docker run

• Copy the config.yml

    $ docker run --rm --entrypoint cat dickverbunt/log-to-telegram  /app/config.yml > config.yml
  

• Add TelegramBot api and chatID to config.yml

• Add triggers to the list to config.yml

• Run

    $ docker run -v {location of config.yml}:/app/config.yml -v {location of log file}:/app/file.log dickverbunt/logtotelegram
  

• Ready! When a line gets added to the log file and matches a trigger it will send this to Telegram.

Docker compose

• Copy the config.yml

    $ docker run --rm --entrypoint cat dickverbunt/log-to-telegram  /app/config.yml > config.yml
  

• Add TelegramBot api and chatID to config.yml

• Add triggers to the list to config.yml

• Add to docker-compose.yml

log-to-telegram:
    image: dickverbunt/log-to-telegram
    container_name: log-to-telegram
    volumes:
      - /{path-to}/config.yml:/app/config.yml
      - /{path-to-log-file}:/app/file.log
    restart: unless-stopped

• Run

    $ docker-compose up -d
  

• Ready! When a line gets added to the log file and matches a trigger it will send this to Telegram.

Notes

• In config.yml it's possible to edit the timeout period.
• Logs will be printed to the terminal. There's also a /app/debug.log file.
