options: debug: type: boolean default: False description: Enable debug logging. verbose: type: boolean default: False description: Enable verbose logging. use-syslog: type: boolean default: False description: | Setting this to True will allow supporting services to log to syslog. rabbit-user: type: string default: neutron description: Username used to access RabbitMQ queue rabbit-vhost: type: string default: openstack description: RabbitMQ vhost data-port: type: string default: description: | Space-delimited list of bridge:port mappings. Ports will be added to their corresponding bridge. The bridges will allow usage of flat or VLAN network types with Neutron and should match this defined in bridge-mappings. . Ports provided can be the name or MAC address of the interface to be added to the bridge. If MAC addresses are used, you may provide multiple bridge:mac for the same bridge so as to be able to configure multiple units. In this case the charm will run through the provided MAC addresses for each bridge until it finds one it can resolve to an interface name. Port can also be a linuxbridge bridge. In this case a veth pair will be created, the ovs bridge and the linuxbridge bridge will be connected. It can be useful to connect the ovs bridge to juju bridge. dpdk-bond-mappings: type: string default: description: | Space-delimited list of bond:port mappings. The DPDK assigned ports will be added to their corresponding bond, which in turn will be put into the bridge as specified in data-port. . This option is supported only when enable-dpdk is true. dpdk-bond-config: type: string default: ":balance-tcp:active:fast" description: | Space delimited list of bond:mode:lacp:lacp-time, where the arguments meaning is: . * bond - the bond name. If not specified the configuration applies to all bonds * mode - the bond mode of operation. Possible values are: - active-backup - No load balancing is offered in this mode and only one of the member ports is active/used at a time. - balance-slb - Considered as a static load-balancing mode. Traffic is load balanced between member ports based on the source MAC and VLAN. - balance-tcp - This is the preferred bonding mode. It offers traffic load balancing based on 5-tuple header fields. LACP must be enabled at both endpoints to use this mode. The aggregate link will fall back to default mode (active-passive) in the event of LACP negotiation failure. * lacp - active, passive or off * lacp-time - fast or slow. LACP negotiation time interval - 30 ms or 1 second disable-security-groups: type: boolean default: false description: | Disable neutron based security groups - setting this configuration option will override any settings configured via the neutron-api charm. . BE CAREFUL - this option allows you to disable all port level security within an OpenStack cloud. bridge-mappings: type: string default: 'physnet1:br-data' description: | Space-delimited list of ML2 data bridge mappings with format :. flat-network-providers: type: string default: description: | Space-delimited list of Neutron flat network providers. vlan-ranges: type: string default: "physnet1:1000:2000" description: | Space-delimited list of :: or specifying physical_network names usable for VLAN provider and tenant networks, as well as ranges of VLAN tags on each available for allocation to tenant networks. firewall-driver: type: string default: description: | Firewall driver to use to support use of security groups with instances; valid values include iptables_hybrid (default) and openvswitch (>= Mitaka on Ubuntu 16.04 or later). ext-port: type: string default: description: | Deprecated: Use bridge-mappings and data-port to create a network which can be used for external connectivity. You can call the network external and the bridge br-ex by convention, but neither is required A space-separated list of external ports to use for routing of instance traffic to the external public network. Valid values are either MAC addresses (in which case only MAC addresses for interfaces without an IP address already assigned will be used), or interfaces (eth0) enable-local-dhcp-and-metadata: type: boolean default: false description: | Enable local Neutron DHCP and Metadata Agents. This is useful for deployments which do not include a neutron-gateway (do not require l3, lbaas or vpnaas services) and should only be used in-conjunction with flat or VLAN provider networks configurations. dnsmasq-flags: type: string default: description: | Comma-separated list of key=value config flags with the additional dhcp options for neutron dnsmasq. Note, this option is only valid when enable-local-dhcp-and-metadata option is set to True. instance-mtu: type: int default: description: | Configure DHCP services to provide MTU configuration to instances within the cloud. This is useful in deployments where its not possible to increase MTU on switches and physical servers to accommodate the packet overhead of using GRE tunnels. dns-servers: type: string default: description: | A comma-separated list of DNS servers which will be used by dnsmasq as forwarders. This option only applies when the enable-local-dhcp-and-metadata options is set to True. prevent-arp-spoofing: type: boolean default: true description: | Enable suppression of ARP responses that don't match an IP address that belongs to the port from which they originate. . Only supported in OpenStack Liberty or newer, which has the required minimum version of Open vSwitch. . NOTE: this feature is deprecated and removed in Openstack >= Ocata. As of that point the only way to disable protection will be via the port security extension (see LP 1691080 for info). enable-dpdk: type: boolean default: false description: | Enable DPDK fast userspace networking; this requires use of DPDK supported network interface drivers and must be used in conjunction with the data-port configuration option to configure each bridge with an appropriate DPDK enabled network device. dpdk-socket-memory: type: int default: 1024 description: | Amount of hugepage memory in MB to allocate per NUMA socket in deployed systems. . Only used when DPDK is enabled. dpdk-socket-cores: type: int default: 1 description: | Number of cores to allocate to DPDK per NUMA socket in deployed systems. . Only used when DPDK is enabled. dpdk-driver: type: string default: description: | Kernel userspace device driver to use for DPDK devices, valid values include: . vfio-pci uio_pci_generic . Only used when DPDK is enabled. enable-sriov: type: boolean default: false description: | Enable SR-IOV NIC agent on deployed units; use with sriov-device-mappings to map SR-IOV devices to underlying provider networks. Enabling this option allows instances to be plugged into directly into SR-IOV VF devices connected to underlying provider networks alongside the default Open vSwitch networking options. sriov-device-mappings: type: string default: description: | Space-delimited list of SR-IOV device mappings with format . : . Multiple mappings can be provided, delimited by spaces. sriov-numvfs: type: string default: auto description: | Number of VF's to configure each PF with; by default, each SR-IOV PF will be configured with the maximum number of VF's it can support. Either use a single integer to apply the same VF configuration to all detected SR-IOV devices or use a per-device configuration in the following format . : . Multiple devices can be configured by providing multi values delimited by spaces. . NOTE: Changing this value will disrupt networking on all SR-IOV capable interfaces for blanket configuration or listed interfaces when per-device configuration is used. worker-multiplier: type: float default: description: | The CPU core multiplier to use when configuring worker processes for this services e.g. metadata-agent. By default, the number of workers for each daemon is set to twice the number of CPU cores a service unit has. When deployed in a LXD container, this default value will be capped to 4 workers unless this configuration option is set. # Network config (by default all access is over 'private-address') os-data-network: type: string default: "" description: | The IP address and netmask of the OpenStack Data network (e.g., 192.168.0.0/24) . This network will be used for tenant network traffic in overlay networks. .
