Octavia is an open source, operator-scale load balancing solution designed to work with OpenStack. It accomplishes its delivery of load balancing services by managing a fleet of virtual machines, known as amphorae, which it spins up on demand.
Octavia is designed to “plug in” to Neutron LBaaS in the same way that any proprietary vendor solution would: through a Neutron LBaaS version 2 driver interface. Octavia plans to supplant Neutron LBaaS as the load balancing solution for OpenStack. At that time, third-party vendor drivers that presently “plug in” to Neutron LBaaS will plug in to Octavia instead. For end-users, this transition should be relatively seamless, because Octavia supports the Neutron LBaaS v2 API and it has a similar CLI interface.

group: octaviaEach openstack formula provide set of phases (logical bloks) that will help to
build flexible upgrade orchestration logic for particular components. The list of phases might and theirs descriptions are listed in table below:
+===============================+======================================================+ | <app>.upgrade.service_running | Ensure that all services for particular application | | | are enabled for autostart and running | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.service_stopped | Ensure that all services for particular application | | | disabled for autostart and dead | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.pkg_latest | Ensure that packages used by particular application | | | are installed to latest available version. | | | This will not upgrade data plane packages like qemu | | | and openvswitch as usually minimal required version | | | in openstack services is really old. The data plane | | | packages should be upgraded separately by apt-get | | | upgrade or apt-get dist-upgrade | | | Applying this state will not autostart service. | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.render_config | Ensure configuration is rendered actual version. + +-------------------------------+------------------------------------------------------+ | <app>.upgrade.pre | We assume this state is applied on all nodes in the | | | cloud before running upgrade. | | | Only non destructive actions will be applied during | | | this phase. Perform service built in service check | | | like (keystone-manage doctor and nova-status upgrade)| +-------------------------------+------------------------------------------------------+ | <app>.upgrade.upgrade.pre | Mostly applicable for data plane nodes. During this | | | phase resources will be gracefully removed from | | | current node if it is allowed. Services for upgraded | | | application will be set to admin disabled state to | | | make sure node will not participate in resources | | | scheduling. For example on gtw nodes this will set | | | all agents to admin disable state and will move all | | | routers to other agents. | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.upgrade | This state will basically upgrade application on | | | particular target. Stop services, render | | | configuration, install new packages, run offline | | | dbsync (for ctl), start services. Data plane should | | | not be affected, only OpenStack python services. | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.upgrade.post | Add services back to scheduling. | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.post | This phase should be launched only when upgrade of | | | the cloud is completed. | +-------------------------------+------------------------------------------------------+ | <app>.upgrade.verify | Here we will do basic health checks (API CRUD | | | operations, verify do not have dead network | | | agents/compute services) | +-------------------------------+------------------------------------------------------+
