################################
Configuring Vyos with cloud-init
################################
Vyos uses cloud-init to configure itself automatically in cloud environments.
There is a Meta-Data module ``cc_vyos.py`` that takes care of the
cloud-specific configuration.
Additional module ``cc_vyos_userdata.py`` introduces a new parameter
``vyos_config_commands`` into User-Data (``#cloud-config``). This parameter
should be a list of VyOS configuration commands that will be applied during
deployment. This module will run last.
Commands requirements:
* one command per line
* if command ending by value, it must be inside single quotes:
``set some option 'value'``, ``delete some option 'value'``
* a single-quote symbol is not allowed inside command or value
The commands' list produced by the ``show configuration commands`` command on a
VyOS router should comply with all the requirements, so it is easy to get a
proper commands' list by copying it from another router.
Usage example (User-Data content):
.. code-block:: none
#cloud-config
vyos_config_commands:
- set system host-name 'demo123'
- set system ntp server 1.pool.ntp.org
- set system ntp server 2.pool.ntp.org
- delete interfaces ethernet eth2 address
- set interfaces ethernet eth2 address '192.0.2.1/24'
