The program has currently tested with TOSCA templates. -The only required argument is ``--template-file``. By default, the ``--template-type`` is set to ``tosca`` which is the only supported template type at present. -The value to the ``--template-file`` is a path to the file that needs to be translated. The file, flat YAML template or CSAR, can be specified as a local file in your -system or via URL. - -For example, a TOSCA hello world template can be translated by running the following command from the project location:: - - python heat_translator.py --template-file=translator/tests/data/tosca_helloworld.yaml - -This should produce a translated Heat Orchestration Template on the command line. The translated content can be saved to a desired file by setting --output-file=<path>. -For example: :: - - python heat_translator.py --template-file=translator/tests/data/tosca_helloworld.yaml --template-type=tosca --output-file=/tmp/hot_helloworld.yaml - -An optional argument can be provided to handle user inputs parameters. Also, a template file can only be validated instead of translation by using --validate-only=true -optional argument. The command below shows an example usage:: - - python heat_translator.py --template-file=<path to the YAML template> --template-type=<type of template e.g. tosca> --validate-only=true - -Alternatively, you can install a particular release of Heat-Translator as available at https://pypi.python.org/pypi/heat-translator. -In this case, you can simply run translation via CLI entry point:: - heat-translator --template-file=translator/tests/data/tosca_helloworld.yaml --template-type=tosca - -Things To Consider ------------------- -* When use Heat-Translator in an OpenStack environment, please ensure that you have one or more preferred flavors and images available in your OpenStack - environment. To find an appropriate flavor and image, that meets constraints defined in the TOSCA template for the HOST and OS capabilities of TOSCA Compute node, - the Heat-Translator project first runs a query against Nova flavors and Glance images. During the query call, it uses the metadata of flavors and images. - If call to Nova or Glance can not be made or no flavor or image is found, the Heat-Translator project will set flavor and image from a pre-defined set of values (as listed in /home/openstack/heat-translator/translator/hot/tosca/tosca_compute.py) - with the best possible match to the constraints defined in the TOSCA template. -* The ``key_name`` property of Nova server is irrelevant to the TOSCA specification and can not be used in TOSCA template. In order to use it in - the translated templates, the user must provide it via parameters, and the heat-translator will set it to all resources of ``OS::Nova::Server`` type. -* Since properties of TOSCA Compute OS and HOST capabilities are optional, the user should make sure that either they set these properties correctly - in the TOSCA template or provide them via CLI parameters in order to find best match of flavor and image. -* The ``flavor`` and ``image`` properties of ``OS::Nova::Server`` resource is irrelevant to the TOSCA specification and can not be used in the TOSCA - template as such. Heat-Translator sets these properties in the translated template based on constraints defined per TOSCA Compute OS and HOST - capabilities. However, user may required to use these properties in template in certain circumstances, so in that case, TOSCA Compute can be extended - with these properties and later used in the node template. For a good example, refer to the ``translator/tests/data/test_tosca_flavor_and_image.yaml`` test - template. -* The Heat-Translator can be used to automatically deploy translated TOSCA template given that your environment has python-heatclient and python-keystoneclient. - This can be achieved by providing ``--deploy`` argument to the Heat-Translator. You can provide desired stack name by providing it as ``--stack-name <name>`` - argument. If you do not provide ``--stack-name``, an unique name will be created and used. - Below is an example command to deploy translated template with a desired stack name:: - heat-translator --template-file translator/tests/data/tosca_helloworld.yaml --stack-name mystack --deploy -* The Heat-Translator supports translation of TOSCA templates to Heat Senlin - resources (e.g. ``OS::Senlin::Cluster``) but that requires to use a specific - TOSCA node type called ``tosca.policies.Scaling.Cluster``. - The ``tosca.policies.Scaling.Cluster`` is a custom type that derives from - ``tosca.policies.Scaling``. For example usage, refer to the - ``tosca_cluster_autoscaling.yaml`` and ``hot_cluster_autoscaling.yaml`` - provided under the ``translator/tests/data/autoscaling`` and - ``translator/tests/data/hot_output/autoscaling`` directories respectively in - the heat-translator project (``https://github.com/openstack/heat-translator``). - When you use ``tosca.policies.Scaling`` normative node type, the - Heat-Translator will translate it to ``OS::Heat::AutoScalingGroup`` Heat - resource. Related example templates, ``tosca_autoscaling.yaml`` and - ``hot_autoscaling.yaml`` can be found for reference purposes under the same - directory structure mentioned above. -* With the version 0.7.0 of Heat-Translator, output of multiple template files - (for example, nested templates in autoscaling) can be accessed via newly - introduced API called ``translate_to_yaml_files_dict(<output_filename>)`` - where ``<output_filename>`` is the name of file where you want to store parent - HOT template. The return value of this API call will be a dictionary in HOT - YAML with one or multiple file names as keys and translated content as values. - In order to use this on the command line, simply invoke Heat-Translator with - ``--output-file`` argument. Here, the parent template will be stored in the - value specified to the ``--output-file``. Whereas, child templates, if any, - will be saved at the same location of the parent template. - - Below is an example of how to call the API in your code, where - ``translator`` is an instance of Heat-Translator:: - - yaml_files = translator.translate_to_yaml_files_dict(filename) - - Below is an example of how to use this on the command line:: - - heat-translator --template-file translator/tests/data/autoscaling/tosca_autoscaling.yaml --output-file /tmp/hot.yaml
