Building or downloading a deploy ramdisk image
==============================================

Ironic depends on having an image with the
:ironic-python-agent-doc:`ironic-python-agent (IPA) <>`
service running on it for controlling and deploying bare metal nodes.

Two kinds of images are published on every commit from every branch of
:ironic-python-agent-doc:`ironic-python-agent (IPA) <>`

* DIB_ images are suitable for production usage and can be downloaded from
  https://tarballs.openstack.org/ironic-python-agent/dib/files/.

  * For Train and older use CentOS 7 images.
  * For Ussuri and newer use CentOS 8 images.

  .. warning:: CentOS 7 master images are no longer updated and must not be
               used.

* TinyIPA_ images are suitable for CI and testing environments and can be
  downloaded from
  https://tarballs.openstack.org/ironic-python-agent/tinyipa/files/.
