bifrost-create-dib-image
This role uses diskimage-builder to create a bootable disk image or ramdisk.
Requirements
This role requires:
- Ansible 2.0
Role Variables
The role can use the disk-image-create or ramdisk-image-create scripts. Which script is used is controlled by the build_ramdisk variable. The default is false.
build_ramdisk: false
The dib_env_vars are settings for the diskimage-builder environment variables which allow settings to be passed to elements that are being utilized to build a disk image. More information on diskimage-builder can be found at: http://git.openstack.org/cgit/openstack/diskimage-builder/
dib_env_vars: DIB_CLOUD_INIT_DATASOURCES: "ConfigDrive" ELEMENTS_PATH: "/opt/stack/diskimage-builder/elements"
The final destination of the image is specified by dib_imagename.
dib_imagename: "/path/to/image.qcow2"
dib_os_element controls which OS will be used to build the image.
dib_os_element: "ubuntu"
dib_elements is a space-separated list of elements that will be added to the resulting disk image.
dib_elements: "vm serial-console simple-init"
dib_packages is a comma-separated list of packages to be installed on the resulting disk image.
dib_packages: "traceroute,python-devel"
dib_os_release can be utilized to set the DIB_RELEASE environment
variable for semi-dynamic disk image creation by a user or the
test script. By default, it is not set, but an example if
dib_os_element is set to debian, then a user could choose
the jessie release.
dib_os_release: jessie
