## YANG Suite Resources

DevNet landing page: [developer.cisco.com/yangsuite](https://developer.cisco.com/yangsuite)

Documentation: [developer.cisco.com/docs/yangsuite](https://developer.cisco.com/docs/yangsuite)

## Prerequisites

To use the resources in this repository, you must install Docker on the system where you want to run YANG Suite. In addition, since this YANG Suite repository uses Docker Compose, your system needs Docker Compose. Docker Desktop for Mac and Docker Desktop for Windows installations include Compose and you can install those using instructions at https://docs.docker.com/install. For Linux, follow [these specific instructions to install Docker Compose on Linux systems](https://docs.docker.com/compose/install/#install-compose-on-linux-systems).

## Quick Start with Docker:

1. Clone this repository

2. Run start_yang_suite.sh

3. Access the tool at http://localhost or https://localhost:8443

` git clone https://github.com/CiscoDevNet/yangsuite cd yangsuite/docker/ ; ./start_yang_suite.sh `

Docker-based YANG Suite Installation

The yangsuite/docker/start_yang_suite.sh script performs the following:

• Prompts for username, password, and email which will be the superuser to yangsuite.

• Gives the choice of creating test SSL/TLS certificate and key.

• Creates an environment file needed for the yangsuite docker container install.

• Runs docker-compose up.

Self-signed Certificate for testing

The SSL/TLS certificates installed with the nginx container should be obtained or generated using a trusted certificate authority. As a convenience the yangsuite/docker/start_yang_suite.sh script will generate a self-signed certificate/key to get you going quickly.

WARNING: Official SSL/TLS certificate/key should be obtained and copied to yangsuite/docker/nginx directory rather than using the test SSL/TLS certificate/key generated by the start_yang_suite.sh script.

Customization

The yangsuite/docker/yangsuite/production.py file contains Django settings. The possible settings are extensive and information can found at https://www.djangoproject.com/.

Adding/Updating plugins can be done through the Admin–>Manage plugins page or by copying the plugin wheels into the yangsuite/docker/yangsuite/ directory, uncomment the appropriate lines in the yangsuite/docker/yangsuite/dockerfile, and run:

docker-compose up –build

Access YANG Suite Docker Install with web browser

• The nginx container redirects port 80 to port 8443 which is used to interface with the yangsuite core. Connect to http://localhost or https://localhost:8443. NOTE: A complaint about the certificate will appear if it was generated using “start_yang_suite.sh”.

• The yangsuite-restconf plugin uses port 443 to communicate to your Cisco device so enable restconf in the YANG Suite Device profile page for devices that support that protocol.

• If port 8443 is not available for use on the server, change the port number in the docker-compose.yml file and the nginx.conf file.

• If port 443 is not available for use on the server, change the port number in the docker-compose.yml file, configure the new restconf port on the Cisco device, and configure the correct restconf port in the YANG Suite Device profile.

• Login using username set during install.

Python Virtualenv Installation

WARNING: HTTPS support is not available unless a web server is installed like NGINX and frontended with uwsgi. Instructions for that can be found searching online.

• Create a Python 3.6, 3.7, or 3.8 virtural environment and activate it.

• Type pip install yangsuite[core]

• Use yangsuite to start the yangsuite server

• User is prompted to set superuser credentials.

• Use ctrl-c to stop the yangsuite server

• Connect to http://localhost:8480.

• Login using user set at install.

• Install other plugins using Admin–>Manage plugins page.

Configuring yangsuite Server

• Activate the virtual environment

• Type yangsuite -h
