GNS3 Docker Summary
GNS3 Docker appliances are the easiest to import into GNS3 as they are simply pulled from the Docker Hub. Once you have the appliance file from the GNS3 Registry you can simply import it and go. Below we will cover importing some of the more useful docker appliances that are available.
Common Useful Appliances
- Open vSwitch – A simple container running a basic 16 port Open vSwitch. This is a lightweight, flexible switch that you can use when you do not need something heavier like a Cisco or Arista image.
- WebTerm – This is a simple container with a firefox install (Useful for Appliance GUI management), a terminal, and troubleshooting command line tools.
- Ubuntu – This is a simple Ubuntu Xenial container that can be used as end points in your simulations.
