--- features: - | The Stein release of Octavia introduces the octavia-lib python module. This library enables provider drivers to integrate easier with the Octavia API by providing a shared set of coding objects and interfaces. upgrade: - | The Stein release of Octavia adds the driver-agent controller process. This process is deployed along with the Octavia API process and uses unix domain sockets for communication between the provider drivers using octavia-lib and the driver-agent. When upgrading to Stein, operators should make sure that the /var/run/octavia directry is available for the driver-agent with the appropriate ownership and permissions for the driver-agent and API processes to access it. The operator may need to make sure the driver-agent process starts after installation. For example, a systemd service may need to be created and enabled for it.
