Pike Series Release Notes

16.0.0

New Features

  • The os_swift role now supports the swift3 middleware, allowing access to swift via the Amazon S3 API. This feature can enabled by setting swift_swift3_enabled to true.

  • Capping the default value for the variable swift_proxy_server_workers to 16 when the user doesn’t configure this variable and if the swift proxy is in a container. Default value is half the number of vCPUs available on the machine if the swift proxy is not in a container. Default value is half the number of vCPUs available on the machine with a capping value of 16 if the proxy is in a container.

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

  • The task dropping the swift 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_swift 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 swift_*_init_config_overrides variables which use the config_template task to change template defaults.

  • Swift container-sync has been updated to use internal-client. This means a new configuration file internal-client.conf has been added. Configuration can be overridden using the variable swift_internal_client_conf_overrides.
