KubeNetLab (KNL) is a k8s operator creates and manages virtual network topology consists of VNF/CNF for learning and testing purposes.
### [Check here](https://hujun-open.github.io/knldoc/) for installation & usage guide.
KNL has following key features:
1. Running on top of k8s with capability of to scale out to entire k8s cluster. e.g. a single lab topology could span across multiple servers.
2. Topology is defined via KNL `Lab` CR, standard k8s tool like `kubectl` or `k9s` could be used to create/manage labs, while KNL cli tool `knlcli` provides more user friendly CLI operations.
3. Supports both CNF and VNF, following are node types supported today:
- Nokia vSIM
- Nokia SR-SIM
- Nokia VSR-I
- Nokia MAG-c
- Nokia SRLinux
- General Virtual Machine
- General pod
Follow YAML defines a simple example-lab contains a Nokia SR-SIM and a Nokia vSIM, with default chassis configuration, connects to each other via a virtual link `link1`.
```yaml
apiVersion: knl.kubenetlab.net/v1beta1
kind: Lab
metadata:
name: example-lab
namespace: knl-system
spec:
links:
link1:
nodes:
- node: srsim-1
- node: vsim-1
```
Use KNL command line tool `knlcli` to check the created Lab, the two lab nodes(`srsim-1` and `vsim-1`) run on two different servers (`worker-1` and `worker-2`), `link1` spans across these two servers.
```bash
user@svr-1:~$ knlcli show
example-lab:
Node Type Chassis Pods Worker/PodIP
srsim-1 SRSIM SR-7 example-lab-srsim-1 worker-1/10.244.2.92
vsim-1 VSIM SR-7 virt-launcher-example-lab-vsim-1-1-cjfn6 worker-2/10.244.0.95
virt-launcher-example-lab-vsim-1-a-lvhqd worker-2/10.244.0.115
Link Nodes
link1 srsim-1
vsim-1
```
## knlcli
`knlcli` is the command line tool for the KNL, [download from here](https://github.com/hujun-open/knlcli/releases)
