# L2S-M Installation Guide (Custom Installation)
This guide provides detailed steps for installing the L2S-M Kubernetes operator, enabling you to create and manage virtual networks within your Kubernetes cluster. This custom installation is intended for debugging or understanding the L2S-M components and their functionality.
## Introduction
The L2S-M custom installation is designed for debugging purposes and gaining a deeper understanding of the L2S-M components. Follow the steps below to install the L2S-M Kubernetes operator and configure virtual networks.
## Prerequisites
Before proceeding, ensure that you meet the prerequisites outlined in the [Prerequisites section](./deployment/README.md). Refer to the [./deployment/README.md](./deployment/README.md) file for detailed instructions on meeting these requirements.
## Custom Installation Steps
Follow the steps below to perform the custom installation of L2S-M:
1. Create the virtual interface definitions using the following command:
```bash
kubectl create -f ./deployments/custom-installation/interfaces_definitions
```
2. Create the Kubernetes account Service Account and apply their configuration by applying the following command:
```bash
kubectl create -f ./deployments/config/
```
3. Create the Kubernetes Persistent Volume by using the following kubectl command:
```bash
kubectl create -f ./deployments/custom-installation/mysql/
```
4. Before deploying the L2S-M operator, it is neccessary to label your master node as the "master" of the cluster. To do so, get the names of your Kubernetes nodes, select the master and apply the "master" label with the following command:
```bash
kubectl get nodes
kubectl label nodes [your-master-node] dedicated=master
```
5. Deploy the L2S-M Controller by using the following command:
```bash
kubectl create -f ./deployments/custom-installation/deployController.yaml
```
You can check that the deployment was successful if the pod enters the "running" state using the *kubectl get pods* command.
6. After the previous preparation, (make sure the controller is running) you can deploy the operator in your cluster using the YAML deployment file:
```bash
kubectl create -f ./deployments/custom-installation/deployOperator.yaml
```
Once these two pods are in running state, you can finally deploy the virtual switches and custom CRD
7. This is done by:
**First deploying the virtual OVS Daemonset:**
```bash
kubectl create -f ./deployments/custom-installation/deploySwitch.yaml
```
And check there is a pod running in each node, with ```kubectl get pods -o wide```
8. And launch the CRD definition by:
```bash
kubectl create -f ./deployments/custom-installation/l2sm-network-crd.yaml
```
## Configuring Vxlans
Each node enables the creation of custom L2S-M networks, as can be seen in the [examples section](../../examples/) section. But for communicating pods that are in different Nodes of the cluster, additional configuration must be done, of configuring the Vxlan tunnels between them.
You can proceed to configure Vxlans by following the steps outlined in [the vxlan configuration guide.](../deployment/vxlans.md)

# L2S-M VxLAN configuration guide
In order to connect the switches between themselves, an additional configuration must be done. A configuration file specifying which nodes we want to connect and which IP addresses their switches have will be made, and then a script will be run in each **l2sm-switch**, using this configuration file.
a. Create a file anywhere or use the reference in ./configs/sampleFile.json. In this installation, this file will be used as a reference.
b. In this file, you will specify, using the template shown in the reference file, the name of the nodes in the cluster and the IP addresses of **the switches** running on them. For example:
```bash
$ kubectl get pods -o wide
>NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
>l2sm-controller-d647b7fb5-lpp2h 1/1 Running 0 30m 10.1.14.55 l2sm1 <none> <none>
>l2sm-operator-7d487d8468-lhgkx 2/2 Running 0 2m11s 10.1.14.56 l2sm1 <none> <none>
>l2sm-switch-8p5td 1/1 Running 0 71s 10.1.14.58 l2sm1 <none> <none>
>l2sm-switch-xdkvz 1/1 Running 0 71s 10.1.72.111 l2sm2 <none> <none>
```
In this example we have two nodes: l2sm1 and l2sm2, with two switches, with IP addresses 10.1.14.58 and 10.1.72.111.
We want to connect them directly, so we modify the reference file, ./configs/sampleFile.json:
```json
[
{
"name": "<NODE_SWITCH_1>",
"nodeIP": "<IP_SWITCH_1>",
"neighborNodes": ["<NODE_SWITCH_2>"]
},
{
"name": "<NODE_SWITCH_2>",
"nodeIP": "<IP_SWITCH_2>",
"neighborNodes": ["<NODE_SWITCH_1>"]
}
]
```
Note: The parameters to be changed are shown in the NODE and IP columns of the table above.
Example of how it looks:
```json
[
{
"name": "l2sm1",
"nodeIP": "10.1.14.58",
"neighborNodes": ["l2sm2"]
},
{
"name": "l2sm2",
"nodeIP": "10.1.72.111",
"neighborNodes": ["l2sm1"]
}
]
```
Note: Any number of nodes can be configured, as long as the entry is in this file. The desired connections are under the neighborNodes field, in an array, such as this other example, where we add a neighbor to l2sm2: ["l2sm1","l2sm3"]
Once this file is created, we inject it to each node using the kubectl cp command:
```bash
kubectl cp ./configs/sampleFile.json <pod-name>:/etc/l2sm/switchConfig.json
```
And then executing the script in the switch-pod:
```bash
kubectl exec -it <switch-pod-name> -- /bin/bash -c 'l2sm-vxlans --node_name=$NODENAME /etc/l2sm/switchConfig.json'
```
This must be done in each switch-pod. In the provided example, using two nodes, l2sm1 and l2sm2, we have to do it twice, in l2-ps-8p5td and l2-ps-xdkvz.
When the exec command is done, we should see an output like this:
```bash
kubectl exec -it l2sm-switch-8p5td -- /bin/bash -c 'l2sm-vxlans --node_name=$NODENAME /etc/l2sm/switchConfig.json'
Defaulted container "l2sm-switch" out of: l2sm-switch, wait-for-l2sm-controller (init)
Created vxlan between node l2sm1 and node l2sm2.
```

# Vlink 'ping-pong' example
## Introduction
This document provides a guide for L2S-M users. It focuses on creating a virtual link (`vlink`) network and managing traffic flows between pods across different nodes using L2S-M components.
## Prerequisites
- A Kubernetes cluster
- Multus CNI installed
- L2S-M and all of its components deployed
## Overview of Components
- **L2S-M Operator**: A Kubernetes operator that listens for Kubernetes events and manages network configurations programmatically. It interacts with the L2S-M Controller and uses a database to store network configurations and state.
- **L2S-M Controller**: An SDN controller based on ONOS, leveraging OpenFlow 1.3 to communicate with L2S-M Switches and manage network flows.
- **L2S-M Switch**: Pods that facilitate traffic flows as per the L2S-M Controller's instructions, ensuring isolated and direct connectivity between specific pods.
## Creating a Vlink Network
The first step involves creating a `vlink` network, named "vlink-sample", using our L2SMNetwork CRD. This network facilitates direct, isolated communication between pods across different nodes, through custom paths.
```yaml
apiVersion: l2sm.k8s.local/v1
kind: L2SMNetwork
metadata:
name: vlink-sample
spec:
type: vlink
config: |
{
"overlay-parameters": {
"path": {
"name": "first-path",
"FromEndpoint": "node-a",
"ToEndpoint": "node-e",
"links": ["link-ac","link-cd","link-de"],
"capabilities": {
"bandwidthBits": "20M",
"latencyNanos": "8e5"
}
},
"reverse-path": {
"name": "second-path",
"fromEndpoint": "node-e",
"toEndpoint": "node-a",
"links": ["link-ed","link-db","link-ba"]
}
}
}
```
### Process Overview
1. **Vlink Creation**: Deploy the `vlink-sample` YAML configuration to define the vlink network.
2. **L2SM Operator Activation**: Upon recognizing the new network configuration, the L2SM operator initiates, contacting the L2SM controller. This process includes saving the network path information for future use.
3. **L2SM Controller**: The controller is informed about the new network but does not initiate traffic flow immediately. It waits for pods to be connected to the network.
## Deploying Pods with Network Annotations
Deployment involves creating pods with specific annotations to connect them to the `vlink-sample` network. This section explains how PodA and PodB are deployed and managed within the network.
### Deploying pod 'ping'
```yaml
apiVersion: v1
kind: Pod
metadata:
name: ping
labels:
app: ping-pong
annotations:
l2sm/networks: '[
{ "name": "vlink-sample",
"ips": ["192.168.1.2/24"]
}]'
spec:
containers:
- name: router
command: ["/bin/ash", "-c", "trap : TERM INT; sleep infinity & wait"]
image: alpine:latest
securityContext:
capabilities:
add: ["NET_ADMIN"]
nodeName: NodeA
```
- **Pod Configuration**: Pod 'ping' is defined with the `vlink-sample` annotation and an "ips" argument specifying its IP address. If no IP is specified, the connection defaults to layer 2.
- **Connection to L2SM-Switch**: Pod 'ping' is attached via Multus to an L2S.M component known as the l2sm-switch, controlled by the L2S-M controller. This grants 'ping' two network interfaces: the default (provided by Flannel or Calico) and the new vlink interface.
### Deploying PodB
```yaml
apiVersion: v1
kind: Pod
metadata:
name: pong
labels:
app: ping-pong
annotations:
l2sm/networks: '[
{ "name": "vlink-sample",
"ips": ["192.168.1.3/24"]
}]'
spec:
containers:
- name: router
command: ["/bin/ash", "-c", "trap : TERM INT; sleep infinity & wait"]
image: alpine:latest
securityContext:
capabilities:
add: ["NET_ADMIN"]
nodeName: NodeE
```
- **Node Placement**: Pod 'pong' is created on NodeE with the `vlink-sample` network annotation but uses a different IP address than pod 'ping'.
- **Network Connectivity**: The L2SM controller then establishes the necessary intents and flows, ensuring traffic between 'ping' and 'pong' traverses the predefined nodes. This setup guarantees direct, isolated connectivity between the two pods.
