build-images

An Ansible role for building TripleO undercloud and overcloud images. The role can either operate directly against a host (direct) or setup a build environment inside of a libvirt guest using libguestfs-tools (isolated).

It starts by creating the overcloud images from the provided yaml files. It then uses the convert-image role from tripleo-quickstart to turn the overcloud-full.qcow2 image into an undercloud image. Finally, it injects the previously created overcloud-full and ironic-python-agent images into this new undercloud image.

Requirements

• convert-image role from tripleo-quickstart (if building an undercloud image)
• fetch-images role from tripleo-quickstart (if using isolated build)
• modify-image role from tripleo-quickstart-extras
• repo-setup role from tripleo-quickstart-extras

Role Variables

• images_working_dir -- Directory on the host where images and logs will be placed
• images_destroy_working_dir -- Whether to destroy the previous image directory before starting. (Default true)
• overcloud_image_build_script -- Template used for the overcloud image build
• overcloud_image_build_log -- Log file for output from the image build script.
• build_image_isolated -- Whether to use libguestfs to create an isolated build environment. (Default true)
• build_isolation_image_url -- URL for image to use as the isolated build environment. (Currently requires an .md5 file in the same location because the fetch-images role from quickstart is used to get the image)
• build_undercloud -- Whether to build an undercloud image. (Default true)
• package_images -- Whether to create tarballs and md5s for all of the produced images. (Default true)
• overcloud_repo_paths -- List of repo paths that will be passed to DIB for package installs in the overcloud images. These repos will also be copied on to the undercloud image.
• image_build_yaml_paths -- List of yaml files to be passed to the overcloud image build. (Defaults to yamls packaged in tripleo-common. In order to produce security hardened images, the alternate overcloud-hardened-images need to be used instead of the overcloud-images ones).
• image_build_extract_list -- List of artifacts to extract from the isolated build environment after building.
• inject_images -- List of artifacts to inject into the undercloud image
• skip_build_images -- skip building images if there present or cached (default: true), setting it to false will add '--no-skip' option to openstack image build command.

Example Usage
