If Ansible is run in check mode, the async_results items will not contain failed or finished keys, Ansible will fail:
TASK [tripleo-container-manage : Show all container commands for /var/lib/tripleo-config/container-startup-config/step_1] *****************
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'all_containers_commands' is undefined\n\nThe error appears to be in '/usr/share/ansible/roles/tripleo-container-manage/tasks/main.yml': line 92, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n include_tasks: create.yml\n - name: \"Show all container commands for {{ tripleo_container_manage_config }}\"\n ^ here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes. Always quote template expression brackets when they\nstart a value. For instance:\n\n with_items:\n - {{ foo }}\n\nShould be written as:\n\n with_items:\n - \"{{ foo }}\"\n"}
