Neutron (the project formerly known as Quantum) – Network

Couch To OpenStack

- Deploy an additional node- Modify resource allocations as needed- … Let’s take a look:

Vagrantfile Review

- BEFORE you vagrant up:- Make sure you have at least 8 GB RAM available

just for the VMs- You can decrease RAM required by modifying the

Vagrantfile- git clone

https://github.com/bunchc/Couch_to_OpenStack.git - cd Couch_to_OpenStack- vagrant up

The Rest of the Series

Use the automated Cinder Install and manually install Quantum

Remember we have a G+ Support group here:http://bit.ly/C2OSGooglePlus

Homework Review

- Creates the Controller, Compute, Cinder and Quantum Nodes

- Sets variables required for Quantum deployment

- Creates a Quantum Service and Endpoint in Keystone

- Updates MySQL- Creates a Quantum DB- Assigns the Quantum User to the DB

- Installs Quantum- Configures Quantum settings

Build – What’s it doing?

- Networking Services for Cloud Instances

- Replaces nova-network

- Advanced capabilities such as plugins for managing network vendor gear and software, load balancing, API for applications to interact with and respond to network management

Neutron Intro

Cinder Architecture

Neutron ComponentsComponent Purpose

neutron-server Allow API access for users and other OpenStack services

neutron-*-plugin-agent

Allow Neutron to dictate network policy to Open vSwitch

neutron-l3-agent Provide L3 Services to the OpenStack Instances

neutron-dhcp-agent Provide DHCP addressing to the Instances

ovs-vswitchd* Open vSwitch – provide networking for the Instances

Thanks Sean Winn for helping out with the Neutron Session tonight. I look forward to him coming back for a session of his own on a future podcast.

Thank you Dan Wendlandt and your team at VMware for the great workflow that I used in the Neutron lab. Viewers can see the VMware Team’s OpenStack Summit session on the OpenStack Foundation YouTube Channel: http://www.youtube.com/watch?v=_pLPtGiGh9M

Acknowledgements

For next week’s session, we will be having C2OS Office Hours. This will allow us to review what we have accomplished up until this point

1. If you have not had a chance to try out the test environments, now is the perfect time to do so.

2. If you are already caught up with what we’ve done so far, try extending your environment add another node to the deployment:

1. Additional Nova nodes2. Additional Cinder nodes

3. Post ideas, questions, comments on the Google Plus Community: http://bit.ly/C2OSGooglePlus

Homework!
