# Offering alternative Chef + Vagrant Riak cluster setup to the following blog post at basho:
# http://blog.basho.com/2011/02/04/creating-a-local-riak-cluster-with-vagrant-and-chef/

# Assumes Vagrant 0.7.0+ and VirtualBox 4.0+

# Now you should be able to launch your X (where X=4 in this case) vagrant VMs with the following:
# % vagrant up db1
# % vagrant up db2
# % vagrant up db3
# % vagrant up db4
# % vagrant up webapp
