Introduce TaskFlowServiceController which uses taskflow jobboard feature and saves jobs info into persistence backend. Jobboard could be operated via RedisTaskFlowDriver or ZookeeperTaskFlowDriver, that could be set via the config. RedisTaskFlowDriver is intoduced as default backend for jobboard. Usage of jobboard allows to resume jobs in case of restart/stop of Octavia controller services. Persistence backend saves state of flow tasks that required in case of resuming job. SQLAlchemy backend is used here. Bump taskflow version to 3.7.1 and add dependency to SQLAlchemy-Utils (required for taskflow sqlalchemy backend support).

Available Provider Drivers
|
|
==========================
|
|
|
|
Octavia supports enabling multiple provider drivers via the Octavia v2 API.
|
|
Drivers, other than the reference Amphora driver, exist outside of the Octavia
|
|
repository and are not maintained by the Octavia team. This list is intended
|
|
to provide a place for operators to discover and find available load balancing
|
|
provider drivers.
|
|
|
|
This list is a **"best effort"** to keep updated, so please check with your
|
|
favorite load balancer provider to see if they support OpenStack load
|
|
balancing. If they don't, make a request for support!
|
|
|
|
.. Note:: The provider drivers listed here may not be maintained by the
|
|
OpenStack LBaaS (Octavia) team. Please submit bugs for these
|
|
projects through their respective bug tracking systems.
|
|
|
|
Drivers are installed on all of your Octavia API instances using pip and
|
|
automatically integrated with Octavia using `setuptools entry points`_. Once
|
|
installed, operators can enable the provider by adding the provider to the
|
|
Octavia configuration file `enabled_provider_drivers`_ setting in the
|
|
[api_settings] section. Be sure to install and enable the provider on all of
|
|
your Octavia API instances.
