Overview
|
|
--------
|
|
|
|
Neutron provides flexible software defined networking (SDN) for OpenStack.
|
|
|
|
This charm is designed to be used in conjunction with the rest of the OpenStack
|
|
related charms in the charm store) to virtualized the network that Nova Compute
|
|
instances plug into.
|
|
|
|
Its designed as a replacement for nova-network; however it does not yet
|
|
support all of the features as nova-network (such as multihost) so may not
|
|
be suitable for all.
|
|
|
|
Neutron supports a rich plugin/extension framework for propriety networking
|
|
solutions and supports (in core) Nicira NVP, NEC, Cisco and others...
|
|
|
|
The Openstack charms currently only support the fully free OpenvSwitch plugin
|
|
and implements the 'Provider Router with Private Networks' use case.
|
|
|
|
See the upstream [Neutron documentation](http://docs.openstack.org/trunk/openstack-network/admin/content/use_cases_single_router.html)
|
|
for more details.

Usage
|
|
-----
|
|
|
|
In order to use Neutron with Openstack, you will need to deploy the
|
|
nova-compute and nova-cloud-controller charms with the network-manager
|
|
configuration set to 'Neutron':
|
|
|
|
nova-cloud-controller:
|
|
network-manager: Neutron
|
|
|
|
This decision must be made prior to deploying Openstack with Juju as
|
|
Neutron is deployed baked into these charms from install onwards:
|
|
|
|
juju deploy nova-compute
|
|
juju deploy --config config.yaml nova-cloud-controller
|
|
juju add-relation nova-compute nova-cloud-controller
|
|
|
|
The Neutron Gateway can then be added to the deploying:
|
|
|
|
juju deploy quantum-gateway
|
|
juju add-relation quantum-gateway mysql
|
|
juju add-relation quantum-gateway rabbitmq-server
|
|
juju add-relation quantum-gateway nova-cloud-controller
|
|
|
|
The gateway provides two key services; L3 network routing and DHCP services.
|
|
|
|
These are both required in a fully functional Neutron Openstack deployment.

TODO
|
|
----
|
|
|
|
* Provide more network configuration use cases.
|
|
* Support VLAN in addition to GRE+OpenFlow for L2 separation.
