Adds support for Layer 7 switching and shared pools
|
|
features to Neutron LBaaS v2. Neutron LBaaS v1 is
|
|
unaffected by this new feature.
|
|
|
|
* Layer 7 policies allow a tenant / user to define
|
|
actions the load balancer may take other than
|
|
routing requests to the default pool.
|
|
* Layer 7 rules control the logic behind whether a
|
|
given Layer 7 policy is followed.
|
|
* Works for HTTP and TERMINATED_HTTPS listeners.
|
|
* Shared pools allow listeners or Layer 7
|
|
REDIRECT_TO_POOL policies to share back-end
|
|
pools.
|
|
upgrade:
|
|
- |
|
|
Upgrade requires a database migration.
|
|
|
|
* Shared-pools introduces a new ``loadbalancer_id``
|
|
column into the ``lbaas_pools`` table.
|
|
* ``lbaas_pools.loadbalancer_id`` column is populated
|
|
from ``lbaas_listeners`` data using ETL in the
|
|
migration.
|
|
* Two new tables are created to handle Layer 7
|
|
switching. These are ``lbaas_l7policies`` and
|
|
``lbaas_l7rules``.
|
|
- |
|
|
Driver updates may be required.
|
|
|
|
* Maintainers of third-party drivers in the neutron-lbaas
|
|
code tree will need to update their drivers to take
|
|
advantage of the new Layer 7 switching features.
|
|
* Pains have been taken to ensure that all interfaces
|
|
(both API and internally) are compatible with the
|
|
new shared-pools feature. Nevertheless, maintainers of
|
|
third-party drivers should double-check their code to
|
|
ensure they haven't made assumptions about
|
|
listener-pool relationships which are now not true.
