Networking Attributes
Basic networking configuration is controlled with the following attributes:
openstack["compute"]["network"]["network_manager"]
- Defaults to "nova.network.manager.FlatDHCPManager". Set to "nova.network.manager.VlanManager" to configure VLAN Networking.openstack["compute"]["network"]["dmz_cidr"]
- A CIDR for the range of IP addresses that will NOT be SNAT'ed by the nova network controlleropenstack["compute"]["network"]["public_interface"]

- If True, send a dhcp release on instance termination. (Default is false on "fedora", "redhat", "centos")
You can have the cookbook automatically create networks in Nova for you by adding a Hash to the openstack["compute"]["networks"]
Array.
Note: The openstack-compute::nova-setup
recipe contains the code that creates these pre-defined networks.
Each Hash must contain the following keys:
ipv4_cidr
- The CIDR representation of the subnet. Supplied to the nova-manage network create command as--fixed_ipv4_range
label
- A name for the network
In addition to the above required keys in the Hash, the below keys are optional:
num_networks
- Passed as-is tonova-manage network create
as the--num_networks
option. This overrides the defaultnum_networks
nova.conf value.network_size
- Passed as-is tonova-manage network create
as the--network_size
option. This overrides the defaultnetwork_size
nova.conf value.bridge
- Passed as-is tonova-manage network create
as the--bridge
option.bridge_interface
-- Passed as-is tonova-manage network create
as the--bridge_interface
option. This overrides the defaultvlan_interface
nova.conf value.dns1
- Passed as-is tonova-manage network create
as the--dns1
option.dns2
- Passed as-is tonova-manage network create
as the--dns2
option.multi_host
- Passed as-is tonova-manage network create
as the--multi_host
option. Values should be either 'T' or 'F'vlan
- Passed as-is tonova-manage network create
as the--vlan
option. Should be the VLAN tag ID.
By default, the openstack["compute"]["networks"]

-
openstack["compute"]["networks"]["public"]["label"]
- Network label to be assigned to the public network on creation -
openstack["compute"]["networks"]["public"]["ipv4_cidr"]

Testing
Please refer to the TESTING.md for instructions for testing the cookbook.
Berkshelf
Berks will resolve version requirements and dependencies on first run and
store these in Berksfile.lock. If new cookbooks become available you can run
berks update
to update the references in Berksfile.lock. Berksfile.lock will
be included in stable branches to provide a known good set of dependencies.
Berksfile.lock will not be included in development branches to encourage
development against the latest cookbooks.
