# coreos-vagrant is configured through a series of configuration
# options (global ruby variables) which are detailed below. To modify
# these options, first copy this file to "config.rb". Then simply
# uncomment the necessary lines, leaving the $, and replace everything
# after the equals sign..
# Change basename of the VM
# The default value is "core", which results in VMs named starting with
# "core-01" through to "core-${num_instances}".
#$instance_name_prefix="core"
# Official CoreOS channel from which updates should be downloaded
#$update_channel='alpha'
$update_channel='stable'
# Log the serial consoles of CoreOS VMs to log/
# Enable by setting value to true, disable with false
# WARNING: Serial logging is known to result in extremely high CPU usage with
# VirtualBox, so should only be used in debugging situations
#$enable_serial_logging=false
# Enable port forwarding of Docker TCP socket
# Set to the TCP port you want exposed on the *host* machine, default is 2375
# If 2375 is used, Vagrant will auto-increment (e.g. in the case of $num_instances > 1)
# You can then use the docker tool locally by setting the following env var:
# export DOCKER_HOST='tcp://127.0.0.1:2375'
#$expose_docker_tcp=2375
# Enable NFS sharing of your home directory ($HOME) to CoreOS
# It will be mounted at the same path in the VM as on the host.
# Example: /Users/foobar -> /Users/foobar
#$share_home=false
# Customize VMs
#$vm_gui = false

# For example,
# $shared_folders = {'/path/on/host' => '/path/on/guest', '/home/foo/app' => '/app'}
# or, to map host folders to guest folders of the same name,
# $shared_folders = Hash[*['/home/foo/app1', '/home/foo/app2'].map{|d| [d, d]}.flatten]
