Bases:
object
- abstract get_add_vip_subflow()[source]¶
Get a subflow that adds a VIP to a distributor
- Requires
distributor_id (string) - The ID of the distributor to create the VIP on.
- Requires
vip (object) - The VIP object to create on the distributor.
- Requires
vip_alg (string) - The optional algorithm to use for this VIP.
- Requires
vip_persistence (string) - The persistence type for this VIP.
- Returns
A TaskFlow Flow that will add a VIP to the distributor
This method will return a TaskFlow Flow that adds a VIP to the distributor by perfoming the necessary steps to plug the VIP and configure the distributor to start receiving requests on this VIP.
- abstract get_create_distributor_subflow()[source]¶
Get a subflow to create a distributor
- Requires
load_balancer (object) - Load balancer object associated with this distributor
- Provides
distributor_id (string) - The created distributor ID
- Returns
A TaskFlow Flow that will create the distributor
This method will setup the TaskFlow Flow required to setup the database fields and create a distributor should the driver need to instantiate one. The flow must store the generated distibutor ID in the flow.
- abstract get_delete_distributor_subflow()[source]¶
Get a subflow that deletes a distributor
- Requires
distributor_id (string) - The ID of the distributor to delete
- Returns
A TaskFlow Flow that will delete the distributor
This method will return a TaskFlow Flow that deletes the distributor (if applicable for the driver) and cleans up any associated database records.
- abstract get_drain_amphorae_subflow()[source]¶
Get a subflow that drains connections from amphorae
- Requires
distributor_id (string) - The ID of the distributor to drain amphorae from
- Requires
amphorae (tuple) - Tuple of amphora objects to drain from distributor.
- Returns
A TaskFlow Flow that will drain the listed amphorae on the distributor
This method will return a TaskFlow Flow that configures the distributor to stop sending new connections to the amphorae in the list. Existing connections will continue to pass traffic to the amphorae in this list.
- abstract get_register_amphorae_subflow()[source]¶
Get a subflow that Registers amphorae with the distributor
- Requires
distributor_id (string) - The ID of the distributor to register the amphora on
- Requires
amphorae (tuple) - Tuple of amphora objects to register with the distributor.
- Returns
A TaskFlow Flow that will register amphorae with the distributor
This method will return a TaskFlow Flow that registers amphorae with the distributor so it can begin to receive requests from the distributor. Amphora should be ready to receive requests prior to this call being made.
- abstract get_remove_vip_subflow()[source]¶
Get a subflow that removes a VIP from a distributor
- Requires
distributor_id (string) - The ID of the distributor to remove the VIP from.
- Requires
vip (object) - The VIP object to remove from the distributor.
- Returns
A TaskFlow Flow that will remove a VIP from the distributor
This method will return a TaskFlow Flow that removes the VIP from the distributor by reconfiguring the distributor and unplugging the associated port.
- abstract get_unregister_amphorae_subflow()[source]¶
Get a subflow that unregisters amphorae from a distributor
- Requires
distributor_id (string) - The ID of the distributor to unregister amphorae from
- Requires
amphorae (tuple) - Tuple of amphora objects to unregister from distributor.
- Returns
A TaskFlow Flow that will unregister amphorae from the distributor
This method will return a TaskFlow Flow that unregisters amphorae from the distributor. Amphorae in this list will immediately stop receiving traffic.
