My k3OS Vagrant box and vagrantfile

1. Build the vagrant box image using Packer:

packer build template.json

2. Run the Vagrant box:

vagrant up

You can then login to the box using vagrant ssh. See Vagrant Docs for more details on how to use Vagrant.

The generated box does not have the Virtualbox Guest Additions installed. Most of the configuration options will not work. this is specially true for:

• config.vm.hostname
• config.vm.synced_folder
• config.vm.network

The shell provisioner is working but requires some tweaking. The provisioning shell script will be put into /tmp/vagrant-shell. The file can be written but can not be executed. To mitigate this limitation, one have to set the upload_path option.

config.vm.provision 'shell',
  upload_path: '/home/rancher/vagrant-shell',
  inline: <<-SHELL
mkdir -p /mnt
mount /dev/sda1 /mnt
cat <<EOF > /mnt/k3os/system/config.yaml
k3os:
  token: EbvX0V38syjPQBZJ71tb9EIHbyL5mISBqDSTa2aJt7LSCF1JEW
  password: rancher
EOF
reboot
SHELL

The above example also shows how the k3OS config can be changed. When you do so, you have to set the password to rancher. If this is not the case, vagrant will not be able to login.
