Puppet Class: neutron::agents::dhcp
- Defined in:
- manifests/agents/dhcp.pp
Overview
Class: neutron::agents::dhcp
Setups Neutron DHCP agent.
Parameters
- package_ensure
-
(optional) Ensure state for package. Defaults to ‘present’.
- enabled
-
(optional) Enable state for service. Defaults to ‘true’.
- manage_service
-
(optional) Whether to start/stop the service Defaults to true
- debug
-
(optional) Show debugging output in log. Defaults to $::os_service_default.
- state_path
-
(optional) Where to store dnsmasq state files. This directory must be writable by the user executing the agent. Defaults to ‘/var/lib/neutron’.
- resync_interval
-
(optional) The DHCP agent will resync its state with Neutron to recover from any transient notification or rpc errors. The interval is number of seconds between attempts. Defaults to 30.
- interface_driver
-
(optional) Defaults to ‘neutron.agent.linux.interface.OVSInterfaceDriver’.
- dhcp_driver
-
(optional) Defaults to $::os_service_default.
- root_helper
-
(optional) Defaults to ‘sudo neutron-rootwrap /etc/neutron/rootwrap.conf’. Addresses bug: bugs.launchpad.net/neutron/+bug/1182616 Note: This can safely be removed once the module only targets the Havana release.
- dnsmasq_config_file
-
(optional) Override the default dnsmasq settings with this file. Defaults to $::os_service_default
- dnsmasq_dns_servers
-
(optional) List of servers to use as dnsmasq forwarders. Defaults to $::os_service_default.
- dnsmasq_base_log_dir
-
(optional) base log dir for dnsmasq logging. Defaults to $::os_service_default.
- dnsmasq_local_resolv
-
(optional) Enables the dnsmasq service to provide name resolution for instances via DNS resolvers on the host running the DHCP agent. Defaults to $::os_service_default.
- dnsmasq_lease_max
-
(optional) Limit number of leases to prevent a denial-of-service. Defaults to $::os_service_default.
- dnsmasq_enable_addr6_list
-
(optional) Enable dhcp-host entry with list of addresses when port has multiple IPv6 addresses in the same subnet. Defaults to $::os_service_default.
- enable_isolated_metadata
-
(optional) enable metadata support on isolated networks. Defaults to false.
- enable_force_metadata
-
(optional) enable metadata support on all networks. Defaults to $::os_service_default
- enable_metadata_network
-
(optional) Allows for serving metadata requests coming from a dedicated metadata access network whose cidr is 169.254.169.254/16 (or larger prefix), and is connected to a Neutron router from which the VMs send metadata request. This option requires enable_isolated_metadata = True Defaults to false.
- dhcp_broadcast_reply
-
(optional) Use broadcast in DHCP replies Defaults to $::os_service_default.
- purge_config
-
(optional) Whether to set only the specified config options in the dhcp config. Defaults to false.
- availability_zone
-
(optional) The availability zone of the agent. Neutron will only schedule dhcp on the agent based on availability zone Defaults to $::os_service_default
- ovs_integration_bridge
-
(optional) Name of Open vSwitch bridge to use Defaults to $::os_service_default
- ovsdb_connection
-
(optional) The URI used to connect to the local OVSDB server Defaults to $::os_service_default
- ovsdb_agent_ssl_key_file
-
(optional) The SSL key file to use for Neutron agents to connect to OVSDB Defaults to $::os_service_default
- ovsdb_agent_ssl_cert_file
-
(optional) The SSL cert file to use for Neutron agents to connect to OVSDB Defaults to $::os_service_default
- ovsdb_agent_ssl_ca_file
-
(optional) The SSL CA cert file to use for Neutron agents to connect to OVSDB Defaults to $::os_service_default
- report_interval
-
(optional) Set the agent report interval. By default the global report interval in neutron.conf ([agent]/report_interval) is used. This parameter can be used to override the reporting interval for the dhcp-agent. Defaults to $::os_service_default
- rpc_response_max_timeout
-
(Optional) Maximum seconds to wait for a response from an RPC call Defaults to: $::os_service_default
