Sample sessions using curl¶
Read the Glossary, and General pages first.
A list of all endpoints is available in Endpoints
Warning
Note that the output of the samples can be truncated in order to simplify their understanding. Please read the documentation for the exact output meaning.
Server version¶
Check the server version with a simple curl command:
# curl "http://localhost:3080/v2/version"
{
"local": false,
"version": "2.1.4"
}
List computes¶
List all the compute servers:
# curl "http://localhost:3080/v2/computes"
[
{
"compute_id": "local",
"connected": true,
"host": "127.0.0.1",
"name": "local",
"port": 3080,
"protocol": "http",
"user": "admin"
}
]
There is only one compute server where nodes can be run in this example. This compute as a special id: local, this is the local server which is embedded in the GNS3 controller.
Create a project¶
The next step is to create a project:
# curl -X POST "http://localhost:3080/v2/projects" -d '{"name": "test"}'
{
"name": "test",
"project_id": "b8c070f7-f34c-4b7b-ba6f-be3d26ed073f",
}
Create nodes¶
Using the project id, it is now possible to create two VPCS nodes:
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes" -d '{"name": "VPCS 1", "node_type": "vpcs", "compute_id": "local"}'
{
"compute_id": "local",
"console": 5000,
"console_host": "127.0.0.1",
"console_type": "telnet",
"name": "VPCS 1",
"node_id": "f124dec0-830a-451e-a314-be50bbd58a00",
"node_type": "vpcs",
"project_id": "b8c070f7-f34c-4b7b-ba6f-be3d26ed073f",
"status": "stopped"
}
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes" -d '{"name": "VPCS 2", "node_type": "vpcs", "compute_id": "local"}'
{
"compute_id": "local",
"console": 5001,
"console_host": "127.0.0.1",
"console_type": "telnet",
"name": "VPCS 2",
"node_id": "83892a4d-aea0-4350-8b3e-d0af3713da74",
"node_type": "vpcs",
"project_id": "b8c070f7-f34c-4b7b-ba6f-be3d26ed073f",
"properties": {},
"status": "stopped"
}
Link nodes¶
The two VPCS nodes can be linked together using their port number 0 (VPCS has only one network adapter with one port):
# 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}]}'
{
"capture_file_name": null,
"capture_file_path": null,
"capturing": false,
"link_id": "007f2177-6790-4e1b-ac28-41fa226b2a06",
"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
}
],
"project_id": "b8c070f7-f34c-4b7b-ba6f-be3d26ed073f"
}
Start nodes¶
Start the two nodes:
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes/f124dec0-830a-451e-a314-be50bbd58a00/start" -d "{}"
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes/83892a4d-aea0-4350-8b3e-d0af3713da74/start" -d "{}"
Connect to nodes¶
Use a Telnet client to connect to the nodes once they have been started. The port number can be found in the output when the nodes have been created above.
# telnet 127.0.0.1 5000

Stop nodes¶
Stop the two nodes:
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes/f124dec0-830a-451e-a314-be50bbd58a00/stop" -d "{}"
# curl -X POST "http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/nodes/83892a4d-aea0-4350-8b3e-d0af3713da74/stop" -d "{}"
Add visual elements¶
Visual elements like rectangle, ellipses or images in the form of raw SVG can be added to a project.
This will display a red square in the middle of your canvas:
# 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>"}'
Tip: embed PNG, JPEG etc. images using base64 encoding in the SVG.
Add a packet filter¶
Packet filters allow to filter packet on a given link. Here to drop a packet every 5 packets:
Node creation¶
There are two ways to add nodes.
- Manually by passing all the information required to create a new node.
- Using an appliance template stored on your server.
Using an appliance template¶
List all the available appliance templates:
# 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"
}
]
Use the appliance template and add coordinates to select where the node will be put on the canvas:
# curl -X POST http://localhost:3080/v2/projects/b8c070f7-f34c-4b7b-ba6f-be3d26ed073f/appliances/9cd59d5a-c70f-4454-8313-6a9e81a8278f -d '{"x": 12, "y": 42}'
