Example yaml file

image:
  distribution: ubuntu # required
  release: artful # optional
  variant: default # optional
  description: Ubuntu Artful # optional
  expiry: 30d # optional: defaults to 30d
  architecture: x86_64 # optional: defaults to local architecture

source:
  downloader: ubuntu-http
  url: http://cdimage.ubuntu.com/ubuntu-base
  keys:

  keyserver: hkps.pool.sks-keyservers.net # optional

targets:
  lxc:
    create-message: |-
      You just created an Ubuntu container (release=artful, arch=amd64, variant=default)

      To enable sshd, run: apt-get install openssh-server

      For security reason, container images ship without user accounts
      and without a root password.

      Use lxc-attach or chroot directly into the rootfs to set a root password
      or create user accounts.
