Use copytruncate and 'hourly' log rotation by default. Increase the default max number of rotated files to 336, which corresponds to 14 days, so that default period retained as is. With the copytruncate option enabled, logs should be hourly rotated to decrease disk IO load when copying log files around. The default maxsize of 10M is better maintained for often rotations done within a day as well, so log files will not happen to become unexpectedly huge at the end of it. W/o copytruncate, the containerized logrotate sends no signals to processes, as files are only renamed and not unlinked. That makes the files deletion based filter failing, until the default period of 14 days expires. To fix that non-copytruncate case, post-rotate always sends HUP (USR1 for httpd) signals to all processes holding open files in the /var/log/containers host path. That also makes all services reloaded hourly (there is still a random splay applied by cron though) as a side effect. With copytruncate ON, each rotation ensures the old log files will also be deleted, so only affected services will be reloaded. Additionally, send USR1 instead of HUP to reload httpd in containers gracefully.

# == Class: tripleo::profile::base::logging::logrotate
|
|
#
|
|
# Installs a cron job that rotates containerized services logs.
|
|
#
|
|
# === Parameters

|
# [*ensure*]
|
|
# (optional) Defaults to present.
|
|
# Valid values are present, absent.
|
|
#
|
|
# [*minute*]
|
|
# (optional) Defaults to '0'. Configures cron job for logrotate.
|
|
#
|
|
# [*hour*]
|
|
# (optional) Defaults to '*'. Configures cron job for logrotate.
|
|
#
|
|

|
|
# (optional) Defaults to 336 (corresponds to 14 days).
|
|
# Configures the logrotate rotate parameter.
|
|
#
|
|
# [*purge_after_days*]
|
|
# (optional) Defaults to 14.
|
|
# Configures forced purge period for rotated logs.
|
|
# Overrides the rotation and rotate settings.
|
|
#
|
