Build Status

Description

This cookbook installs the OpenStack Network service (formerly project-named Quantum, current name is Neutron) as part of a Chef reference deployment of OpenStack.

More information about the OpenStack Network service is available here

Usage

OpenStack Network's design is modular, with plugins available that handle L2 and L3 networking for various hardware vendors and standards.

Requirements

Chef 11.4.4 or higher required (for Chef environment use)

Cookbooks

The following cookbooks are dependencies:

  • identity
  • openstack-common >= 8.0.0

Recipes

client

  • Install the network client packages

server

  • Installs the openstack-network API server

Identity-registration

  • Registers the OpenStack Network API endpoint and service user with Keystone

Attributes

  • openstack['network']['service_provider'] - Array of service providers (drivers) for advanced services like loadbalancer, VPN, Firewall.

  • openstack["network"]["mq"]["qpid"]["reconnect_limit"] - The limit for the number of times to reconnect before considering the connection to be failed.

  • openstack["network"]["mq"]["qpid"]["reconnect_interval_min"] - Minimum number of seconds between connection attempts.

  • openstack["network"]["mq"]["qpid"]["reconnect_interval_max"] - Maximum number of seconds between connection attempts.

  • openstack["network"]["mq"]["qpid"]["reconnect_interval"] - Equivalent to setting qpid_reconnect_interval_min and qpid_reconnect_interval_max to the same value.

  • openstack["network"]["mq"]["qpid"]["heartbeat"] - Seconds between heartbeat messages sent to ensure that the connection is still alive.

  • openstack["network"]["mq"]["qpid"]["protocol"] - Protocol to use. Default tcp.

  • openstack["network"]["mq"]["qpid"]["tcp_nodelay"] - Disable the Nagle algorithm. default disabled.

Linuxbridge plugin attributes

  • openstack['openstack']['network']['linuxbridge']['tenant_network_type'] - Type of network to allocate for tenant networks. (default 'local')
  • openstack['openstack']['network']['linuxbridge']['network_vlan_ranges'] - Comma-separated list of <physical_network>[:<vlan_min>:<vlan_max>] tuples enumerating ranges of VLAN IDs
  • openstack['openstack']['network']['linuxbridge']['physical_interface_mappings'] - (ListOpt) Comma-separated list of <physical_network>:<physical_interface> tuples mapping physical network names
  • openstack['openstack']['network']['linuxbridge']['enable_vxlan'] - (BoolOpt) enable VXLAN on the agent. (default false)
  • openstack['openstack']['network']['linuxbridge']['ttl'] - (IntOpt) use specific TTL for vxlan interface protocol packets
  • openstack['openstack']['network']['linuxbridge']['tos'] - (IntOpt) use specific TOS for vxlan interface protocol packets

  • openstack['openstack']['network']['linuxbridge']['firewall_driver'] - Firewall driver for realizing neutron security group function

Modular Layer 2 Plugin Configuration

  • openstack['openstack']['network']['ml2']['type_drivers'] - (ListOpt) List of network type driver entrypoints to be loaded from the neutron.ml2.type_drivers namespace.

DHCP Agent Configuration

  • openstack['openstack']['network']['dhcp']['dhcp_delete_namespaces'] - (StrOpt) If True, namespaces will be deleted when a dhcp server is disabled.

L3 Agent Configuration

  • `openstack['openstack']['network']['l3']['router_delete_namespaces'] - (StrOpt) If True, namespaces will be deleted when a router is destroyed.

The following attributes are defined in attributes/default.rb of the common cookbook, but are documented here due to their relevance:

  • openstack['endpoints']['network-api-bind']['host'] - The IP address to bind the api service to
  • openstack['endpoints']['network-api-bind']['port'] - The port to bind the api service to
  • openstack['endpoints']['network-api-bind']['bind_interface'] - The interface name to bind the api service to

If the value of the 'bind_interface' attribute is non-nil, then the network service will be bound to the first IP address on that interface. If the value of the 'bind_interface' attribute is nil, then the network service will be bound to the IP address specified in the host attribute.

Templates

  • api-paste.ini.erb - Paste config for OpenStack Network server
  • neutron.conf.erb - Config file for OpenStack Network server
  • ml2_conf.ini.erb - Configuration of Network ML2 Plugins

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.
