Pike Series Release Notes¶

16.0.4¶

Adds a new flag to enable Octavia V2 API (disabled by default) to facilitate to run Octavia stand alone (without Neutron)

Adds a new flag to toggle Octavia V1 API (the API needed to run in conjunction with Neutron) and enables it by default.

Adds iptables rules to block taffic from the octavia managment network to the octavia container for both ipv4 and ipv6.

Adds a way for the system to automatically create the Octavia management network if octavia_service_net_setup is enabled (DEFAULT). Additional parameters can control the setup.

Adds support for glance-image-id and automatic uploading of the image if octavia_amp_image_upload_enabled is True (Default is False). This is mostly tp work around the limitations of Ansible’s OpenStack support and should not be used in prodcution settings. Instead refer to the documentation to upload images yourself.

New variables have been added to allow a deployer to customize a octavia systemd unit file to their liking.

The task dropping the octavia systemd unit files now uses the config_template action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.

For the os_octavia role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the octavia_*_init_overrides variables which use the config_template task to change template defaults.

The octavia-api service has moved to run as a uWSGI application. You can set the max number of WSGI processes, the number of processes, threads, and buffer size utilizing the octavia_wsgi_processes_max, octavia_wsgi_processes, octavia_wsgi_threads, and octavia_wsgi_buffer_size. Additionally, you can override any settings in the uWSGI ini configuration file using the octavia_api_uwsgi_ini_overrides setting. The uWSGI application will listen on the address specified by octavia_uwsgi_bind_address which defaults to 0.0.0.0.

Deployers may provide a list of custom haproxy template files to copy from the deployment host through the octavia_user_haproxy_templates variable and configure Octavia to make use of a custom haproxy template file with with octavia_haproxy_amphora_template variable.

For the os_octavia role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the octavia_*_init_overrides variables which use the config_template task to change template defaults.

The octavia_keystone_auth_plugin variable has been deprecated. octavia_keystone_auth_type should be used instead to configure authentication type.

Remove octavia_rpc_backend option due to deprecation of rpc_backend option in oslo.messaging.
