A Heat Teamplate Validator
Heat Template Validator
Heat Template Validator (HTV) is a tool created to validate Heat templates (yaml files) and check the parameters' existence in the Openstack server.
What does it do?
The main script htv will analyze every single file from the dir /htv/TemplateLocalStorage. It moves the valid files into the dir /htv/ValidHeatFiles. It moves the warning files into the dir /htv/WarnHeatFiles. It moves the error files into the dir /htv/ErrorHeatFiles and for each file of the error and warn groups it creates a log and then it moves all log files into the dir /htv/Log. At the very beginning of the installation HTV will also create crontab lines inside the /htv/list_cron.txt file.
HTV requires python>=3.5 and pip in order to run. Open the terminal and download the application through pip:
$ pip install htv
Then install and configure the package via htv -i or htv --install:
$ htv -i
This command will create the htv into your home directory with the relative subdirectories (Log, TemplateLocalStorage and so on). There are few simple steps to follow in order to correctly use HTV:
- Move the Heat files into the ./TemplateLocalStorage dir
- Move the open.rc files into the ./rc_files dir After this transfer execute htv -s or htv --shadow:
$ htv -s
Then the application will prompt you the Openstack server password. Remember to enter this command only once: during the HTV installation, or everytime you need to change the Openstack passwords or openrc.hs files. The htv -s command will also generate a list of crontabs in the list_cron.txt file that you can use in your system crontab file depending on which openrc.sh file is needed.
You can choose to run the application using the crontabs created in list_cron.txt. Or to run it no-interactively via htv:
Or in the interactive mode where the application will ask for which openrc file to use for the Openstack authentication:
$ htv /Path/To/The/Openrc/File.sh
After this you are ready to go, the Heat templates will be moved accordingly with their warnings or errors and logs will be created and moved to the /htv//Log dir.
Whenever you want to use htv you first need to move the yaml files to the /htv/TemplateLocalStorage dir.
In case the application directory changes
In case you move the HeatTemplateValidator directory to a different path it is necessary to do as follows:
$ htv -i $ htv -s
This is a requirement in order to generate the new crontabs and having the whole application working.
This application fully functions on Ubuntu and MacOS with python3, pip and python-dev installed. All advice welcome!
