hubot-redis-brain

A hubot script to persist hubot's brain using redis

See src/redis-brain.js for full documentation.

Installation

In hubot project repo, run:

npm install hubot-redis-brain --save

Then add hubot-redis-brain to your external-scripts.json:

``json
[
"hubot-redis-brain"
]
`

Configuration

hubot-redis-brain requires a redis server to work. It uses the REDIS_URL environment variable for determining
where to connect to. The default is on localhost, port 6379 (ie the redis default).

The following attributes can be set using the REDIS_URL

* authentication
* hostname
* port
* key prefix

For example, export REDIS_URL=redis://:password@192.168.0.1:16379/prefix would
authenticate with password, connecting to 192.168.0.1 on port 16379, and store
data using the prefix:storage key.

For a UNIX domain socket, export REDIS_URL=redis://:password@/var/run/redis.sock?prefix would authenticate with password, connecting to /var/run/redis.sock, and store data using the prefix:storage key.

If you need to install and
run your own, most package managers have a package for redis:

* Mac OS X with homebrew: brew install redis
* Ubuntu/Debian with apt: apt-get install redis-server
* Compile from source: http://redis.io/topics/quickstart

$3

If you are using boxen to manage your environment,
hubot-redis-brain will automatically use the boxen-managed redis (ie by using BOXEN_REDIS_URL).

$3

If you are deploying on Heroku, you can add the
Redis Cloud or Redis To Go addon to have automatically configure itself to use it:

* Redis Cloud
* Redis To Go


Other redis addons would need to be configured using REDIS_URL until support
is added to hubot-redis-brain (or hubot-redis-brain needs to be updated to look
for the environment variable the service uses)

$3

If you are using Twemproxy to cluster redis,
you need to turn off the redis ready check which uses the unsupported INFO cmd.

REDIS_NO_CHECK = 1`
