OpenStack Cloud with Calico Networking

This bundle deploys a small OpenStack Cloud (Mitaka release) on Ubuntu 16.04
LTS (Xenial) with Layer 3 networking by Project Calico, providing
Dashboard, Compute, Network, Block Storage, Identity and Image services.

Requirements

This bundle deploys to Juju-managed VMs and/or bare metal servers; it requires
at least 9 VMs and/or bare metal servers.

Servers should have:

  • A minimum of 4GB of physical RAM.
  • Enough CPU cores to support your capacity requirements.

Deployment

juju quickstart u/project-calico/openstack-calico

Components

By default this bundle deploys:

  • 1 node for each OpenStack controller service
  • 2 compute nodes.

Neutron API, Nova Compute and Etcd services are designed to be horizontally
scalable.

To scale Nova Compute:

juju add-unit nova-compute # Add one more unit
juju add-unit -n5 nova-compute # Add 5 more units

To scale Neutron API:

juju add-unit neutron-api # Add one more unit
juju add-unit -n2 neutron-api # Add 2 more unitsa

To scale Etcd:

juju add-unit etcd # Add one more unit
juju add-unit -n2 etcd # add 2 more units

Ensuring it's working

To ensure your cloud is functioning correctly, deploy this bundle and then run
through the following sections.

All commands are executed from within the expanded bundle.

Install OpenStack client tools

In order to configure and use your cloud, you'll need to install the
appropriate client tools:

sudo apt-get -y install python-novaclient python-keystoneclient \
    python-glanceclient python-neutronclient

Accessing the cloud

Check that you can access your cloud from the command line:

source novarc
keystone catalog

You should get a full listing of all services registered in the cloud - which
should include identity, compute, image and network.

Configuring an image

In order to run instances on your cloud, you'll need to install an image to
boot instances from:

mkdir -p ~/images
wget -O ~/images/trusty-server-cloudimg-amd64-disk1.img \
    http://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img
glance image-create --name="trusty" --visibility=public --progress \
    --container-format=bare --disk-format=qcow2 \
    < ~/images/trusty-server-cloudimg-amd64-disk1.img

Configure networking

For the purposes of a quick test, we'll setup a network on an internal subnet.

neutron net-create --shared calico-net
neutron subnet-create calico-net 10.208.168.0/21 --name calico-subnet

This will allow VMs to communicate with each other; the easiest way to allow
external connectivity is to add a route to that subnet pointed at any of the
nova-compute instances.

In a production deployment you'd want to BGP peer your router into the deployed
route reflector. For more information please consult the
Calico External Connectivity documentation.

Booting an instance

First generate a SSH keypair so that you can access your instances once you've
booted them:

nova keypair-add mykey > ~/.ssh/id_rsa_cloud

Note: you can also upload an existing public key to the cloud rather than
generating a new one:

nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey

You can now boot an instance on your cloud:

nova boot --image trusty --flavor m1.small --key-name mykey \
    trusty-test

Configuring and managing services on an OpenStack cloud is complex; take a look
a the OpenStack Admin Guide for a complete reference on how to configure an
OpenStack cloud for your requirements.
