The 'kayobe * host configure' commands no longer use the 'kolla-ansible bootstrap-servers' command, and associated 'baremetal' role in Kolla Ansible. The functionality provided by the 'baremetal' role has been extracted into the openstack.kolla Ansible collection, and split into separate roles. This allows Kayobe to use it directly, and only the necessary parts. This change improves failure handling in these Kayobe commands, and aims to reduce confusion over which '--limit' and '--tags' arguments to provide. This ensures that if a host fails during a host configuration command, other hosts are able to continue to completion. Previously, if any host failed during the Kayobe playbooks, the 'kolla-ansible bootstrap-servers' command would not run. This is useful at scale, where host failures occur more frequently. This change has implications for configuration of Kayobe, since some variables that were previously in Kolla Ansible are now in Kayobe. Several parts of the baremetal role have been split out and used here: * apparmor-libvirt: disable AppArmor rules for libvirt on Ubuntu. * docker: Docker installation & configuration. The docker role in openstack.kolla combines functionality from kolla-ansible and kayobe. * etc-hosts: it proved difficult to generalise this, so we have some almost duplicated the code from kolla-ansible here. Requires delegated fact gathering for the case when --limit is used. * firewall: support to disable UFW, for feature parity. * kolla-packages: miscellaneous package installs & removals. The addition of the stack user to the docker group has been moved to the user bootstrapping playbook, and the docker SDK installation has been moved to the virtualenv setup playbook.
