This program provide a good usage to test the Heat-Translator tool on the command line with expection of similar usage via Heat python client in near future. The TOSCA hello world use case is implemented for quick testing as well. implements blueprint tosca-translator-cli-test-utility Change-Id: Ia4ddf65aafcbe440ea9551ccc2648de4a7c88c97

Test the heat-translator from command line as:
|
|
#python heat_translator.py
|
|
--template-file=<path to the YAML template>
|
|
--template-type=<type of template e.g. tosca>
|
|
--parameters="purpose=test"
|
|
Takes three user arguments,
|
|
1. type of translation (e.g. tosca) (required)
|
|
2. Path to the file that needs to be translated (required)
|
|
3. Input parameters (optional)
|
|
|
|
This should be only used for testing purpose. The proper use of
|
|
Heat-Translator tool is via python-heatclient once it made available there.
