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.
Linux host or VM with docker (rootless) installed.
Install kubectl and minikube or kind tool, e.g.
curl -LO "https://dl.k8s.io/release/$(curl -sL https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
minikube:
curl -LO https://github.com/kubernetes/minikube/releases/latest/download/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube && rm minikube-linux-amd64
or kind:
unset version
version=$(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
Expose VM images via http access, e.g.:
docker run --name www -dt --mount type=bind,source=$HOME/images,target=/usr/share/nginx/html -p 8080:80 nginx:latest
Run netclab installation script:
bash <(curl -Ls "https://raw.githubusercontent.com/mbakalarski/netclab/main/netclab-kind.sh")
or
bash <(curl -Ls "https://raw.githubusercontent.com/mbakalarski/netclab/main/netclab-minikube.sh")
with kubevirt arg for netclab with VM images.
To create topology:
cd <Lab folder>
kubectl apply -f ./manifests/
Then connect to console.
For VMs install virtctl:
unset version
version=$(kubectl get kubevirt.kubevirt.io/kubevirt -n kubevirt -o=jsonpath="{.status.observedKubeVirtVersion}")
curl -L -o virtctl https://github.com/kubevirt/kubevirt/releases/download/${version}/virtctl-${version}-linux-amd64
chmod +x virtctl
sudo mv ./virtctl /usr/local/bin/virtctl
and connect:
virtctl console <router name>
For containerized router:
kubectl exec -ti <router name> -- bash
