Mesos Centos OVN and OVS

OVS/OVN installation on Centos:
==============================

# Get the kernel module RPM build for your specific kernels and install them on all the hosts. e.g:
sudo rpm -ivh kmod-openvswitch-2.8.2-1.el7.centos.x86_64.rpm openvswitch-kmod-2.8.2-1.el7.centos.x86_64.rpm

# Building the above kernel rpms. The instructions are at the below link. You only need to build the kernel module rpms. 
# You can ignore about the need to read the fedora instructions for RHEL 7.x series.

MASTER INSTALL OVS and OVN
==========================


if [ ! -f /etc/yum.repos.d/delorean-deps.repo ] ; then
    curl https://trunk.rdoproject.org/centos7/delorean-deps.repo | sudo tee /etc/yum.repos.d/delorean-deps.repo
fi

sudo yum install -y openvswitch openvswitch-ovn-central openvswitch-ovn-host
sudo service openvswitch start
sudo service ovn-northd start
sudo service ovn-controller start

# Install git and pip
sudo yum install git python-pip -y
git clone https://github.com/shettyg/ovn-mesos
cd ovn-mesos
sudo pip install -r requirements.txt
sudo sh install_dcos.sh

# Dangerous next step. May loose mgmt connectivity.
sudo bin/ovn-mesos-util nics-to-bridge eth0

cd ..


PREP ALL HOSTS (both agent and master)
================

CENTRAL_IP=10.10.0.128   # This is the IP of the master
LOCAL_IP=10.10.0.128     # This is the IP of the host. In this example, we are running it on master.
ENCAP_TYPE=geneve

sudo ovs-vsctl set Open_vSwitch . external_ids:ovn-remote="tcp:$CENTRAL_IP:6642" \
  external_ids:ovn-nb="tcp:$CENTRAL_IP:6641" \
  external_ids:ovn-encap-ip=$LOCAL_IP \
  external_ids:ovn-encap-type="$ENCAP_TYPE"

# Below two commands only for master. For SSL, we will need more steps.
sudo ovn-nbctl set-connection ptcp:6641
sudo ovn-sbctl set-connection ptcp:6642


AGENT INSTALL OVS AND OVN
=========================
