Having fun with SDN in chain of NFV with some Docker ! :hear_no_evil:

SDNFV101

Introduction

Steps

Initiation

1. Install docker on each VM
2. Install OVS on each VM

sudo apt install openvswitch-switch
sudo apt install ovn-common

3. Install ONOS on each VM

sudo docker pull onosproject/onos

Connectivity test with containrs on OVS + OpenFlow

based on Open Virtual Networking With Docker.

1. Create bridge interface

sudo ovs-vsctl add-br ovs-br1

2. Provide ip address to host ovs-br1 bridge

sudo ifconfig ovs-br1 173.16.1.1 netmask 255.255.255.0 up

3. Create docker instances

sudo docker run -t -i --name container1 1995parham/ubuntu-network /bin/bash
sudo docker run -t -i --name container2 1995parham/ubuntu-network /bin/bash

4. Connect them together and VSwitch

sudo ovs-docker add-port ovs-br1 eth1 container1 --ipaddress=173.16.1.2/24
sudo ovs-docker add-port ovs-br1 eth1 container2 --ipaddress=173.16.1.3/24

5. Turn the OpenFlow on

sudo ovs-vsctl set-controller br0 tcp:`docker-ip onos-1`:6653

Let's build tunnels between OVSs

based on Configuring VXLAN and GRE Tunnels on OpenvSwitch

1. Create bridge interface

sudo ovs-vsctl add-br ovs-br1

2. Create tunnels 😂

sudo ovs-vsctl add-port ovs-br1 vx1 -- set interface vx1 type=vxlan options:remote_ip=?

ONOS cluster

based on Running the published Docker ONOS images.

1. Run your docker image

$ sudo docker run  -t -d --name onos1 onosproject/onos
<cid>
$ sudo docker run  -t -d --name onos2 onosproject/onos
<cid>
$ sudo docker run  -t -d --name onos3 onosproject/onos
<cid>

2. Cluster-ize your instances

# Forms ONOS cluster using REST API of each separate instance.
wget https://raw.githubusercontent.com/opennetworkinglab/onos/master/tools/package/bin/onos-form-cluster

chmod u+x onos-form-cluster

./onos-form-cluster -u karaf -p karaf `docker-ip onos1` `docker-ip onos2` `docker-ip onos3`

3. Connect to your ONOS !

ssh -p 8101 karaf@`docekr-ip onso3`

Protocol	Port
SSH	8101
HTTP	8181

Service chaining based on docker

We want to create 3 containers that thier network chains together.

1. Create docker network if necessary

sudo docker netowrk create --driver=bridge bridge-name

2. Create a normal container in each subnet

sudo docker run -ti --rm --name=c1 ubuntu
sudo docker run -ti --rm --name=c3 --network=bridge ubuntu

3. Create middlebox container

sudo docker build --no-cache -t middlebox containers/middlebox
sudo docker run -ti --rm --name=c2 middlebox eth0
