pipe2slack

Simple script that outputs all data inserted into a named pipe to slack via an incoming webhook (https://api.slack.com/incoming-webhooks).

Dependencies

This script uses a couple python libraries

requests
configparser
argparse

Installation

A couple things need to be done to get everything up and running

Install dependencies
Download the source (I choose to place it in /opt/pipe2slack and symlink it to /usr/local/bin/pipe2slack)
Create the following tmpfiles.d(5) fragment: p /run/syslog-slack 0770 root root - -
Named pipes can also be created adhoc with mknod(1): mknod NAME p or mkfifo(1): mkfifo NAME
Setup the daemon using the supplied pipe2slack.service
Create a environment file in /etc/default/pipe2slack

To set this up with syslog just pipe the output of syslog to the pipe like this: *.* |/run/syslog-slack

DO NOT DO THIS EXACTLY, THIS WILL LOG EVERYTHING TO SLACK*, WHICH IS A TERRIBLE IDEA* Think about what you want to send to slack.

Environment File

PIPE=/run/syslog-slack
HOOK=<slack webhook url>
CHANNEL=General
NICKNAME=Syslog-bot

Config file format

[config]
pipe = path to pipe

[slack]
hook = WEBHOOK URL 
channel = Channel name 
nickname = Nick used to post

For example:

[config]
pipe = ./pipe

[slack]
hook = https://hooks.slack.com/services/...
channel = general
nickname = log

This will send the messages written to the named pipe './pipe' to the incoming webhook at https://hooks.slack.com/services/... to the #general channel with the messages labeled as from the user 'log'.
