This Repo will be able store for all the Jinja2 templates, that can be referenced to quickly without having to think about too much :D
To use this Repo you will need to have the following as a miniuium:
- Python 3.6+
- pip
It is recommended to run this within a dev environment, to protect your host system.
I use virtualenv but there plenty of over ways methods can be googled! To install virtualenv and activate your dev environment, please check the docs here
Note: I set my environment, so python 3 is default, if is not default then you will need to python3 and pip3
The necessay modules to run this renderer can be installed by running:
(env)$ pip install -r requirements.txt
Once your environment is set, jinja2 template and YMAL data have been created. You will need to run the command below:
python3 renderer.py yaml_file j2_template
The python script will render YAML data and Jinja2 template and print the output to screen.
(env)$ python3 renderer.py network/junos/vlan/data.yml network/junos/vlan/vlan.j2
set vlans Second_Floor description "VLAN SECOND FLOOR"
set vlans Second_Floor vlan-id 2
set vlans Fourth_Floor description "VLAN FOURTH FLOOR"
set vlans Fourth_Floor vlan-id 4
set vlans Management description "VLAN MANAGEMENT"
set vlans Management vlan-id 10
set vlans First_Floor description "VLAN FIRST FLOOR"
set vlans First_Floor vlan-id 1
set vlans Third_Floor description "VLAN THIRD FLOOR"
set vlans Third_Floor vlan-id 3
To help with troubleshooting or ensuring templates are correct when adding for loops or if statement, for some (like myself) find it easier to have a json output to work out what is happening
$ python3 yaml2dict.py test.yml
