Cisco Modeling Labs (CML) API Demo for simulation lifecycle

Overview

CML2.0 is network simulation platform by Cisco including Routers/Switches/Servers and more.
CML2.0 supports lightweight and easy-to-use GUI as well as over 130 APIs
Not only getting lab simulations information but also creating/deleting labs with configuration files by code
CML APIs helps CI/CD, NetDevOps :-)
To start learning CML APIs, it would be great to start following five demos/hands-on.
Five demos are python3 script on your machine and connecting to your CML2.x server
Enjoy!

Installation

1. Clone the repo

git clone https://github.com/kikuta/CML-Lifecycle-Demo.git

2. cd into directory

cd CML-Lifecycle-Demo

3. Create the virtual environment in a sub dir in the same directory

python3 -m venv venv

4. Start the virtual environment and install requirements.txt and cd into script directory

source venv/bin/activate
pip install -r requirements.txt
cd CMLDemo

5. Change env_lab.py.yourifle to env_lab.py

mv env_lab.py.yourconfig env_lab.py

env_lab.py must include the ip address of your CML, username, and password. You have to change the filename and host/username/password in it.

% cat env_lab.py.yourconfig 
CML = {
    "host": "<cml_ip_address>",
    "username": "<username>",
    "password": "<password>"
}

Demo 1. Get authentication Token

auth.py

% python auth.py 
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJjb20uY2lzY28udmlybCIsImlhdCI6MTU5NjQzNzc0NywiZXhwIjoxNTk2NTI0MTQ3LCJzdWIiOiIxMDEifQ.-csBly7oKqiN8WOcpm7uQFPL2PDiVp__sHAkaLk3NMc

Demo 2. Get Simulated labs information on CML

hellocml.py

% python hellocml.py

% python import.py test-topology.yaml 
Please input an lab title [type q to quit]: test-by-kikuta
test-topology.yaml
<Response [200]>

delete.py

% python delete.py                   
Please input lab ID to be deleted? [type q to quit]: 42aaf9
<Response [200]>

Demo 5. Get a testbed file (yaml) for pyATS

pyats_testbed.py

% python pyats_testbed.py 
Please input lab ID to be deleted? [type q to quit]: 48cadf
