Riak with Docker: Brain Dump

Note

This document _tries_ to outline important items that need to be covered in order to get riak running with docker.

Update system packages -- will migrate system forward to CentOS 5.8. (Optional?)

$ sudo yum update

Install the EPEL Repo:

	var express = require('express')
	, mongoskin = require('mongoskin')

	var app = express()
	app.use(express.bodyParser())

	var db = mongoskin.db('localhost:27017/test', {safe:true});

	app.param('collectionName', function(req, res, next, collectionName){
	req.collection = db.collection(collectionName)

	#!/bin/sh
	TABLE_SCHEMA=$1
	TABLE_NAME=$2

	mytime=`date '+%y%m%d%H%M'`
	hostname=`hostname \| tr 'A-Z' 'a-z'`
	file_prefix="trimax$TABLE_NAME$mytime$TABLE_SCHEMA"
	bucket_name=$file_prefix
	splitat="4000000000"
	bulkfiles=200
