teleglogger

Watches docker logs for regexp and sends a Telegram message when matching. Also sends a message when container dies.

It's something like logspout, but simpler, only with one adapter/route - a Telegram bot chat. I dug most of the code from lospout actually.

Usage

Use ./rebuild.sh to rebuild the project into image tomk/teleglogger.

See docker-compose.yml for usage with containers.

Prerequisities

Before you can use this, you need to create a Telegram bot and get a token (sth like 5747861481:AAfsdfFfgdfgdFGDFGdfgDFGdfg). Then, you need to send a message to the bot and find out chat ID of the conversation.

You can find the chat ID by HTTP request to the Bot API,

$ curl https://api.telegram.org/5747861481:AAfsdfFfgdfgdFGDFGdfgDFGdfg/getUpdates

Look for result[0][message][from][id] in the response JSON.

{
  "ok": true,
  "result": [
    {
      "update_id": 542980616,
      "message": {
        "message_id": 4,
        "from": {
          "id": 568975557, <<<<< This

Environment variables

Teleglogger is configured with envvars, you can see it from the code, but the most important are:

• TG - if unset or "0", it will not send Telegram messages. I.e. you must set it to for example "1" if you want to have Telegram messages sent.
• TG_CHAT - Telegram ChatID
• TG_TOKEN - Telegram Bot token
• MATCHRE - Golang regexp for matching message that you want to be sent to Telegram
• DEBUG - Set to "1" for more verbosity
