When using the customizable filter to modify variables, if a template overrides file is shared between multiple sets of images, it is sometimes possible that a customised variable does not exist for a set of images. A specific example: My template overrides file has this: {% set ironic_inspector_packages_append = ["python-pip"] %} Normally I build binary/centos images. kolla-build -t binary Sometimes however I build a bifrost centos/source image, because bifrost does not support binary images. kolla-build -t source bifrost The ironic inspector image does not define ironic_inspector_packages for the source build, since it does not need any. {% elif install_type == 'source' %} {% if base_distro in ['debian', 'ubuntu'] %} {% set ironic_inspector_packages = ['iptables'] %} {% endif %} {{ macros.install_packages(ironic_inspector_packages | customizable("packages")) }} The install_packages macro copes with the undefined variable, however the customizable filter does not handle the base variable being undefined if a customised example exists. This change allows the customizable filter to ignore undefined variables, even if they have been customised. Change-Id: Ibe2fc91f5b6ceee8f937dd73c235128b2db525b1 Closes-Bug: #1809491 |
