Sample session using curl
|
|
=========================
|
|
|
|
You need to read the :doc:`glossary`, and :doc:`general` before.
|
|
|
|
Full endpoints list is available: :doc:`endpoints`
|
|
|
|
.. warning::
|
|
|
|
Beware the output of this sample is truncated in order
|
|
to simplify the understanding. Please read the
|
|
documentation for the exact output.
|
|
|
|
You can check the server version with a simple curl command:
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl "http://localhost:3080/v2/version"
|
|
{
|
|
"version": "2.0.0dev1"
|
|
}
|
|
|
|
|
|
List computes
|
|
##############
|
|
|
|
We will list the computes node where we can run our nodes:
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl "http://localhost:3080/v2/computes"
|
|
[
|
|
{
|
|
"compute_id": "local",
|
|
"connected": true,
|
|
"host": "127.0.0.1",
|
|
"name": "Local",
|
|
"port": 3080,
|
|
"protocol": "http",
|
|
"user": "admin"
|
|
}
|
|
]
|
|
|
|
In this sample we have only one compute where we can run our nodes. This compute as a special id: local. This
|
|
mean it's the local server embed in the GNS3 controller.
|
|
|
|
Create project
|
|
###############
|
|
|
|
The next step is to create a project.
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl -X POST "http://localhost:3080/v2/projects" -d '{"name": "test"}'
|
|
{
|
|
"name": "test",
|
|
"project_id": "b8c070f7-f34c-4b7b-ba6f-be3d26ed073f",
|
|
}
|
|
|
|
Create nodes
|
|
#############
|
|
|
|
With this project id we can now create two VPCS Node.
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes" -d '{"name": "VPCS 1", "node_type": "vpcs", "compute_id": "local"}'
|

{

}
|
|
|
|
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes" -d '{"name": "VPCS 2", "node_type": "vpcs", "compute_id": "local"}'
|

{

|
|
}
|
|
|
|
The properties dictionnary contains all setting specific to a node type (dynamips, docker, vpcs...)
|
|
|
|
Link nodes
|
|
###########
|
|
|
|
Now we need to link the two VPCS by connecting their port 0 together.
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/links" -d '{"nodes": [{"adapter_number": 0, "node_id": "f124dec0-830a-451e-a314-be50bbd58a00", "port_number": 0}, {"adapter_number": 0, "node_id": "83892a4d-aea0-4350-8b3e-d0af3713da74", "port_number": 0}]}'

|
|
},
|
|
{
|
|
"adapter_number": 0,

"project_id": "b8c070f7-f34c-4b7b-ba6f-be3d26ed073f"
|
|
}
|
|
|
|
Start nodes
|
|
###########
|
|
|
|
Now we can start the two nodes.
|
|
|
|
.. code-block:: shell-session

Connect to nodes
|
|
#################
|
|
|

Everything should be started now. You can connect via telnet to the different Node.
|
|
The port is the field console in the create Node request.

Stop nodes

|

And we stop the two nodes.

Add a visual element
|
|
######################
|
|
|
|
When you want add visual elements to the topology like rectangle, circle, images you can just send a raw SVG.
|
|
This will display a red square in the middle of your topologies:
|
|
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/drawings" -d '{"x":0, "y": 12, "svg": "<svg width=\"50\" height=\"50\"><rect width=\"50\" height=\"50\" style=\"fill: #ff0000\"></rect></svg>"}'
|
|
|
|
Tips: you can embed png/jpg... by using a base64 encoding in the SVG.
|
|
|
|
|
|
Add filter to the link
|
|
######################
|
|
|
|
Filter allow you to add error on a link.
|
|
|
|
.. code-block:: shell-session
|
|
curl -X PUT "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/links/007f2177-6790-4e1b-ac28-41fa226b2a06" -d '{"filters": {"frequency_drop": [5]}}'
|

Creation of nodes
|
|
#################
|
|
|
|
Their is two way of adding nodes. Manual by passing all the information require for a Node.
|
|
|
|
Or by using an appliance. The appliance is a node model saved in your server.
|
|
|
|
Using an appliance
|
|
------------------
|
|
|
|
First you need to list the available appliances
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl "http://localhost:3080/v2/appliances"
|
|
|
|
[
|
|
{
|
|
"appliance_id": "5fa8a8ca-0f80-4ac4-8104-2b32c7755443",
|
|
"category": "guest",
|
|
"compute_id": "vm",
|
|
"default_name_format": "{name}-{0}",
|
|
"name": "MicroCore",
|
|
"node_type": "qemu",
|
|
"symbol": ":/symbols/qemu_guest.svg"
|
|
},
|
|
{
|
|
"appliance_id": "9cd59d5a-c70f-4454-8313-6a9e81a8278f",
|
|
"category": "guest",
|
|
"compute_id": "vm",
|
|
"default_name_format": "{name}-{0}",
|
|
"name": "Chromium",
|
|
"node_type": "docker",
|
|
"symbol": ":/symbols/docker_guest.svg"
|
|
}
|
|
]
|
|
|
|
Now you can use the appliance and put it at a specific position
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# curl -X POST http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f -d '{"x": 12, "y": 42}'
