sentinel-notify-slack

Basics

This script is intended to be used as notification handler for redis-sentinel. It will pass sentinel notifications to Slack channel as specified in configuration.

Prerequisites

1. Slack token created by adding custom integration at https://YOURSLACK.slack.com/apps/manage where YOURSLACK is your slack subdomain component. It might look like this: https://mycompany.slack.com

2. Ruby (tested on 2.4.0)

3. Bundler gem ($ gem install bundler)

Setup

1. Install dependencies from Gemfile ($ bundle install)
2. Copy example config to config.yml (it's the location that shell wrapper expects) and setup token and slack channel

Testing

You can test this script by calling it directly and passing -c config.file and two additional parameters - notification type and notification content. E.g:

./sentinel-notify-slack -c test.yml -- '-odown' 'master mymaster 127.0.0.1 6379'

Running from redis-sentinel

There's additional shell script intended to be used by redis-sentinel. (shell_wrapper.sh)

You can enable it by putting something like this in your sentinel.conf:

sentinel notification-script test /path/to/cloned/repo/shell_wrapper.sh

or at runtime from when connected to your sentinel via redis-cli by calling something like this:

$ redis-cli -p 26379
127.0.0.1:26379> sentinel set mymaster notification-script /path/to/cloned/repo/shell_wrapper.sh
