GNS3-registry

This is the GNS3 registry where user can share appliances and symbols.

Policy for new appliances

We welcome pull requests for new appliances.

Regarding images / disks referenced in new appliance files, we accept links that point to well-known vendor websites or other trusted source websites.

For new contribution, we accept links depending on multiple criteria: the kind of appliance, who submits it and especially if scripts to build the images(s) are provided (packer scripts are recommended for Qemu appliances). Then we will build on our side, verify and upload the image(s) on the GNS3 Sourceforge account.

For Docker appliances, please provide a Dockerfile.

Adding a new appliance

There are two ways to create a new appliance:

• Copy and paste a JSON from the appliances directory
• Run new_appliance.py

After that you can send us a pull request on Github

In schemas/appliance.json you have a JSON with a schema for controlling the file and can be use as documentation for each field.

Versioning

GNS3 checks the schema version, if the schema of an appliance is not supported it shows the error "Please update GNS3 in order to install this appliance".

Schema	min. GNS3 version	Additions
2	1.4.0
3	1.5.0	docker
4	2.0.0	availability qemu/cpus qemu/hd?_disk_interface: sata versions/images/bios_image
5	2.1.0	qemu/console_type: spice
6	2.2.0	qemu/custom_adapters
7	2.2.36	qemu/tpm

Adding a new symbol

Look for examples in the symbols directory.

Docker container

This repository also contains the source of Docker container published by the GNS3 team and that can be used as an appliance in GNS3.

Tools

All tools require python3 and dependencies can be installed using pip:

python3 -m pip install -r requirements.txt

Check appliance files

python3 check.py
python3 check_urls.py

If imagemagick is installed, it will be used to check the symbol properties. Otherwise, an (experimental) internal function will do take care of it.

Create a new appliance

python3 new_appliance.py

Prettify appliances JSON

This will indent the JSON of all appliance and sort the key in same order as the JSON schema.

python3 prettify_appliances.py
