octavia.amphorae.drivers.noop_driver.driver module

class NoopAmphoraLoadBalancerDriver

Bases: AmphoraLoadBalancerDriver, VRRPDriverMixin

check(amphora, timeout_dict=None)

Check connectivity to the amphora.

Parameters:

• amphora – The amphora to query.

• timeout_dict – Dictionary of timeout values for calls to the amphora. May contain: req_conn_timeout, req_read_timeout, conn_max_retries, conn_retry_interval

Raises:

TimeOutException – The amphora didn’t reply

delete(listener)

Delete the listener on the vip.

Parameters:

listener (octavia.db.models.Listener) – listener object, need to use its protocol_port property

Returns:

return a value list (listener, vip, status flag–delete)

At this moment, we just build the basic structure for testing, will add more function along with the development.

finalize_amphora(amphora)

Finalize the amphora before any listeners are configured.

Parameters:

amphora (octavia.db.models.Amphora) – amphora object, need to use its id property

Returns:

None

At this moment, we just build the basic structure for testing, will add more function along with the development. This is a hook for drivers who need to do additional work before an amphora becomes ready to accept listeners. Please keep in mind that amphora might be kept in an offline pool after this call.

get_diagnostics(amphora)

Return ceilometer ready diagnostic data.

Parameters:

amphora (octavia.db.models.Amphora) – amphora object, need to use its id property

Returns:

return a value list (amphora.id, status flag–‘ge t_diagnostics’)

At this moment, we just build the basic structure for testing, will add more function along with the development, eventually, we want it run some expensive self tests to determine if the amphora and the lbs are healthy the idea is that those tests are triggered more infrequent than the health gathering.

get_info(amphora, raise_retry_exception=False)

Returns information about the amphora.

Parameters:

• amphora (octavia.db.models.Amphora) – amphora object, need to use its id property

• raise_retry_exception – Flag if outside task should be retried

Returns:

return a value list (amphora.id, status flag–‘info’)

At this moment, we just build the basic structure for testing, will add more function along with the development, eventually, we want it to return information as: {“Rest Interface”: “1.0”, “Amphorae”: “1.0”, “packages”:{“ha proxy”:”1.5”}} some information might come from querying the amphora

get_interface_from_ip(amphora, ip_address, timeout_dict=None)

Get the interface name from an IP address.

Parameters:

• amphora (octavia.db.models.Amphora) – The amphora to query.

• ip_address (string) – The IP address to lookup. (IPv4 or IPv6)

• timeout_dict (dict) – Dictionary of timeout values for calls to the amphora. May contain: req_conn_timeout, req_read_timeout, conn_max_retries, conn_retry_interval

post_network_plug(amphora, port, amphora_network_config)

Called after amphora added to network

Parameters:

• amphora (octavia.db.models.Amphora) – amphora object, needs id and network ip(s)

• port (octavia.network.data_models.Port) – contains information of the plugged port

• amphora_network_config (octavia.network.data_models. AmphoraNetworkConfig) – A data model containing information about the subnets and ports that an amphorae owns.

This method is optional to implement. After adding an amphora to a network, there may be steps necessary on the amphora to allow it to access said network. Ex: creating an interface on an amphora for a neutron network to utilize.

post_vip_plug(amphora, load_balancer, amphorae_network_config, vrrp_port, vip_subnet, additional_vip_data=None)

Called after network driver has allocated and plugged the VIP

Parameters:

• amphora (octavia.db.models.Amphora)

• load_balancer (octavia.common.data_models.LoadBalancer) – A load balancer that just had its vip allocated and plugged in the network driver.

• amphorae_network_config (octavia.network.data_models. AmphoraNetworkConfig) – A data model containing information about the subnets and ports that an amphorae owns.

• vrrp_port (octavia.network.data_models.Port) – VRRP port associated with the load balancer

• vip_subnet (octavia.network.data_models.Subnet) – VIP subnet associated with the load balancer

Returns:

None

This is to do any additional work needed on the amphorae to plug the vip, such as bring up interfaces.

reload(loadbalancer, amphora=None, timeout_dict=None)

Reload the listeners on the amphora.

Parameters:

• loadbalancer (octavia.db.models.LoadBalancer) – loadbalancer object to reload listeners

Returns:

return a value list (listener, vip, status flag–enable)

At this moment, we just build the basic structure for testing, will add more function along with the development.
