tg44/docker-tag-notification repository overview

⁠docker-tag-notification

A simple service which periodically check docker tags, and if they modified it post them to discord.

⁠Config syntax

The app works with one conf.json which looks like this;

{
    "repos": [
        {
            "name": "alpine",
            "tag": "latest"
        }
    ]
}

⁠Running the app

⁠Local install / dev

You need node 12, start with npm i and then node app.js. For setting the discord server url you need to export DISCORD="mydiscordhookurl" before the service start.

For enable debugging you can export IS_VERBOSE=true

(Or you can add these to a .env file.)

⁠Docker and compose

For docker you can run;

docker run -e DISCORD="mydiscordhookurl" -v ${PWD}/conf:/home/node/app/conf tg44/docker-tag-notification

For docker compose;

version: '3.1'
services:
  docker-tag-notification:
    image: tg44/docker-tag-notification
    restart: unless-stopped
    volumes:
      - /otp/docker-tag-notification/:/home/node/app/conf
    environment:
      - DISCORD=mydiscordhookurl

In the early config/template writing/testing phase, you can add the IS_VERBOSE env var too.

You can also add CRON_EXPRESSION and CRON_TIMEZONE if you want to override the default ones (every 30 minute, Eu/Budapest). The cron starts with seconds!
