Welcome to heat-translator's documentation! Welcome to tosca-parser's documentation!
=========================================== ===========================================
The heat-translator tool is aimed to translate non-heat templates to OpenStack The TOSCA Parser is developed to parse TOSCA Simple Profile in YAML. It reads
Heat Orchestration Template (HOT). Initially the tool is aimed to translate the TOSCA templates and creates an in-memory graph of TOSCA nodes and their
OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) relationship.
to HOT. However, the tool can be easily extended to support any non-heat
template format to produce HOT.

Installation Installation
============ ============
Assuming that OpenStackClient (OSC) is available in your environment, you can easily install Heat-Translator to use with OSC by following three steps:: TOSCA Parser is going to made available as a PyPi library.
git clone https://github.com/openstack/heat-translator
cd heat-translator
python setup.py install
You can also clone the project and use it without any specific OpenStack environment set up as below::
git clone https://github.com/openstack/heat-translator

Usage Usage
===== =====
Use Heat-Translator with OpenStackClient (OSC) The TOSCA Parser can be used as a library by any client program, for example,
---------------------------------------------- OpenStack heat-translator uses it to translate TOSCA to Heat Orchestration
Assuming that OpenStackClient (OSC) is available in your environment, you can easily install Heat-Translator to use with OSC by following three steps:: Template (HOT).
git clone https://github.com/openstack/heat-translator
cd heat-translator
python setup.py install
Once installation is complete, Heat-Translator is ready to use. Currently you can use it in following two ways.
Translate and get output on command line. For example: ::
openstack translate template --template-file /home/openstack/heat-translator/translator/toscalib/tests/data/tosca_helloworld.yaml --template-type tosca
Translate and save output of translated file to a desired destination. For example: ::
openstack translate template --template-file /home/openstack/heat-translator/translator/toscalib/tests/data/tosca_helloworld.yaml --template-type tosca --output-file /tmp/hot_hello_world.yaml
You can learn more about available options by running following help command::
openstack help translate template
Use Heat-Translator on its own
------------------------------
Heat-Translator can be used without any specific OpenStack environment set up as below::
git clone https://github.com/openstack/heat-translator
python heat_translator.py --template-file==<path to the YAML template> --template-type=<type of template e.g. tosca> --parameters="purpose=test"
The heat_translator.py test program is at the root level of the project. The program has currently tested with TOSCA templates.
It requires two arguments::
1. Path to the file that needs to be translated
2. Type of translation (e.g. tosca)
An optional argument can be provided to handle user inputs parameters.
For example, a TOSCA hello world template can be translated by running the following command from the directory where you have cloned the project::
python heat_translator.py --template-file=translator/toscalib/tests/data/tosca_helloworld.yaml --template-type=tosca
This should produce a translated Heat Orchestration Template on the command line. In the near future, new options will be added to save the output
to destination file.
When deploy the translated template with Heat, please keep in mind that you have image registered in the Glance. The Heat-Translator
project sets 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. If there is no possible match found, a null value is set for now.
Per the future plan, an image and flavor will be provided from an online repository.
