To facilitate offline installs, any explicit URLs should be moved to a location where they can be easily overridden with a local equivalent. That way, a default install will use the canonical location, but a user can easily override this behavior in inventory. (Such gymnastics are not necessary for apt/yum/pip, because those can be configured to point to local/alternate repositories independently). ** WIP - Needs *better* documentation ** Change-Id: I9dada2fe769e30abc06dac092b9f47b99969a954 Closes-Bug: #1464787 |

Role Name
This role installs a standalone ironic deployment with all required substrate in order for it to be utilized, including MySQL, RabbitMQ, dnsmasq, nginx. Additionally, it utilizes diskimage-builder to create a bootable disk image.
Requirements
This role requires:
- Ansible 1.9
- Internet Access
Role Variables
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
Testing mode is intended to help facilitate testing of the Bifrost roles and Ironic by utilizing virtual machines on the localhost and the agent_ssh driver. This variable should be set globally for playbooks utilizing the install-ironic role.
testing: false
Node cleaning, which was a feature added to Ironic during the Kilo cycle, removes the previous contents of a node once it has been deleted. Bifrost sets this to true by default, however if testing mode is enabled,
cleaning: true
The Ironic python client and shade libraries can be installed directly from GIT. The default is to utilize pip to install the current versions in pypi, however testing may require master branch or custom patches.
ironicclient_source_install: false shade_source_install: 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/. Additionally, an extra_dib_elements setting exists which is a space separated list of elements to incorporate into the image.
dib_env_vars: DIB_CLOUD_INIT_DATASOURCES: "ConfigDrive" ELEMENTS_PATH: "/opt/stack/diskimage-builder/elements" extra_dib_elements: ""
As for controlling if a partition image is utilized or an image is created with diskimage-builder, the following two settings which are mutually exclusive, can allow a user to choose which logic is utilized.
create_image_via_dib: true transform_boot_image: false
By default this role installs dnsmasq to act as a DHCP server for provisioning hosts. In the event this is not required, set the following configuration:
include_dhcp_server: false
In the event of an external DHCP server being used, the user will need to configure their DHCP server such that PXE, and iPXE chain loading occurs. For additional information for setting up DHCP in this scenario refer to the Bifrost documentation file doc/source/deploy/dhcp.rst. Additional default variables exist in defaults/main.yml, however these are mainly limited to settings which are unlikely to be modified, unless a user has a custom Ironic Python Agent image, or needs to modify where the httpboot folder is set to.
Dependencies
None at this time.
Example Playbook
- hosts: localhost
