NETwork Containerized LAB is a tool for running testbeds with mix of VM and container images, e.g. Cisco csr1000v and Juniper cRPD or Nokia SR Linux.
It is based on kind Kubernetes cluster.
Network topologies are defined via k8s manifest files.
KubeVirt is used for VM support and Multus to have more network interfaces.
Install docker at first.
Then install kubectl and kind tool, e.g.
curl -LO "https://dl.k8s.io/release/$(curl -sL https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
version=$(basename $(curl -s -w %{redirect_url} https://github.com/kubernetes-sigs/kind/releases/latest))
curl -Lo ./kind https://kind.sigs.k8s.io/dl/${version}/kind-linux-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind
Run netclab installation script:
bash <(curl -Ls "https://raw.githubusercontent.com/mbakalarski/netclab/main/netclab_install.sh") kubevirt
or
bash <(curl -Ls "https://raw.githubusercontent.com/mbakalarski/netclab/main/netclab_install.sh") nokubevirt
Expose VM images via http access, e.g.:
docker run --name www -dt --mount type=bind,source=$HOME/images,target=/usr/share/nginx/html -p 8080:80 nginx:latest
To create topology:
cd <Lab folder>
kubectl apply -f ./manifests/
Then connect to console:
virtctl console <router name>
*) virtctl - KubeVirt project; easy installation
and/or for containerized router:
kubectl exec -ti <router name> -- bash
