Slacker is simple email-to-slack gateway. It support basic rules for routing messages to different slack channels from different bots.
Main purpose of slacker is to redirect messages from old-school systems which doesn't support messaging other than email. For example cron and monit (https://mmonit.com/monit/) support only emails as the only system for notifications.
Slacker can be easily built and run via docker:
docker build .Slacker supports simple list of rules for configuring target slack channel, bot name and its avatar depending on email content.
There are two sections:
- default: this is default options for sending message to slack.
- rules: list of rules for matching email message against 'from', 'to' and/or 'subject'.
Each rule in list tested in order. First matched rule is used to update options values from 'default' section of config.
Example config.yml for redirecting email to two channels: #monit and #cron:
# default values for channel, bot name, avatar url, slack token and debug mode
default:
channel: '#general'
username: slacker
icon_url: ''
slack_token: xoxb-00000000000-aaaaaaaaaaaaaaaaaaaaaaaa
debug: false
# list of rules
rules:
- name: Monit rule
from: monit@.* # all emails from monit@localhost will match this rule
options:
username: monit
channel: '#monit'
icon_url: 'https://bitbucket.org/tildeslash/monit/avatar/128'
debug: false
- name: Cron rule
from: root@localhost
subject: Cron.* # cron email subject starts with "Cron..."
options:
username: cron
channel: '#cron'
icon_url: ''
debug: true # will output full email with all X-headers
