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
totrue
.
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 unitTimeoutSec
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. TheRestartSec
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 theswift_*_init_config_overrides
variables which use theconfig_template
task to change template defaults.
Swift container-sync has been updated to use
internal-client
. This means a new configuration fileinternal-client.conf
has been added. Configuration can be overridden using the variableswift_internal_client_conf_overrides
.
