GNS3 Control Tool

This repository holds the source to a control tool that can be used to manipulate GNS3 networks.

Creating a project/network

The load command is used to create a network as a GNS3 project. The input to this command is a YAML formated file that contains the declaration of the nodes and the links between those nodes. An example can be seen in the file example-network.yaml.

Configuration

The GNS3 command tool uses a configuration file that defaults to $HOME/.gns3ctl.yaml. This file can be used to establish persistent flags to the gns3ctl command, such as project, compute, or any of the Global Flags.

WIP - Work In Progress

This tool is very much a work in progress, so use the --help option to discover what can be done and don't be surprised if things break. Also, please feel free to submit issues and, better yet, sumbit a merge request.

Clean GIT History

While this project has been under development internally for a while, when it was made public in December 2022 it was done so without any commit history. This was done out of an abundance of caution to ensure nothing company propriary snuck in the history.

Help

The help command can be used to get more information about the tool's capabilities.
