CONTAINERlab is a Docker orchestration tool for creating virtual network topologies. This article describes how to build and monitor the leaf and spine topology shown above.
Note: Docker testbed describes a simple testbed for experimenting with sFlow analytics using Docker Desktop, but it doesn't have the ability to construct complex topologies.
multipass launch --cpus 2 --mem 4G --name containerlab
multipass shell containerlab
The above commands use the multipass command line tool to create an Ubuntu virtual machine and open shell access.
sudo apt update
sudo apt -y install docker.io
bash -c "$(curl -sL https://get-clab.srlinux.dev)"
Type the above commands into the shell to install CONTAINERlab.
Note: Multipass describes how to build a Mininet network emulator to experiment with software defined networking.
