# 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..

# Size of the CoreOS cluster created by Vagrant
$num_instances=1

# Official CoreOS channel from which updates should be downloaded
$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

# Setting for VirtualBox VMs
#$vb_gui = false
#$vb_memory = 1024
#$vb_cpus = 1
