logrotate is a subordinate charm that ensure that all logrotate.d configurations within /etc/logrotate.d/ folder are modified accordingly to a retention period defined in the charm
cd charm-logrotate
charm build
Add to an existing application using juju-info relation.
Example:
juju deploy ubuntu
juju deploy ./charm-logrotate
juju add-unit ubuntu
juju add-relation ubuntu logrotate
The user can configure the following parameters:
-
logrotate-retention(default:180): The logrotate retention period in days. The charm will go throughALLlogrotate entries in /etc/logrotate.d/ and set therotateconfig to the appropriate value, depending on the rotation interval used. For example if rotation is monthy and retention is 180 days ->rotate 6or rotation is daily and retention is 90 days ->rotate 90or rotation is weekly and retention is 21 days ->rotate 3Weekly will round up the week count, for example if retention is set to 180 days ->rotate 26(26 weeks x 7 days = 182 days) Yearly will put rotate to 1 and increase it with 1 for each 360 days. Monthly will round up, using 30 days for a month. Yearly will round up, adding a year for each 360 days. -
override: (default:[]): JSON formatted field containing a list of files that need to have custom logrotate interval and count. The format is as follows: [ {"path": "/etc/logrotate.d/rotatefile", "rotate": 5, "interval": "weekly"}, {}, ... ]
Mind the double quotes for the properties/values!
Valid options for rotate: any integer value
Valid options for interval: 'daily', 'weekly', 'monthly', 'yearly'
Unit tests have been developed to test return values from the charm helper class, while modifying pre-defined string entries with the logrotate syntax.
