Vagrantfile

# Vagrantfile for a test 3-node autoradio cluster.
#
# By default it will pull autoradio packages from the public
# repository. Set the environment variable LOCAL to a non-empty value
# if you want to use local packages, in which case the 'etcd' and
# 'autoradio' packages should be placed in the same directory as this
# file.
#
# If you have an APT proxy available, you can set the APT_PROXY environment
# variable to its host:port address, and the VMs will use it to retrieve
# Debian packages. This will make the setup step faster.

API_VERSION = "2"

# Note: we shouldn't need to create a host entry for 'etcd' but it is
# faster to set up the cluster this way.
