External Systems support
-------------------------------------
Interaction with **external systems** is made **dynamic**, removing
development cycle to support new endpoint.
In order to define the external system information, TOSCA provides
**dsl_definitions**. Link to TOSCA spec `info 1
<http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html#_Toc494454160>`_,
`info 2 <http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html#_Toc494454173>`_.
Use cases:
* Resource resolution using **REST** (see tab Node Type) or **SQL** (see tab Node Type) external systems
* **gRPC** is supported for remote execution
* Any REST endpoint can be dynamically injected as part of the scripting framework.
Here are some examples on how to populate the system information within the package:
.. list-table::
:widths: 100
:header-rows: 1
* - token-auth
* - .. code-block:: JSON
{
. . .
"dsl_definitions": {

"type": "token-auth",
"url": "http://netbox-nginx.netprog:8080",
"token": "Token 0123456789abcdef0123456789abcdef01234567"
}
}
.. list-table::
:widths: 100
:header-rows: 1
