Logrotate

Introduction

The logrotate utility is designed to simplify the administration of log files on a system which generates a lot of log files. Logrotate allows for the automatic rotation compression, removal and mailing of log files. Logrotate can be set to handle a log file daily, weekly, monthly or when the log file gets to a certain size.

Chart

Right now no public helm chart of logrotate exist, so we have created a PR for that. Till then we are using public chart from stakater-charts, with version 1.0.0 in our cluster. We use umbrella charts to deploy logrotate on our cluster. Currently we are using thisopen in new window repository for elasticsearch deployment

Image

Currently we are using this stakater/logrotate:3.13.0 stakater public image for logrotate in stakater. There is no official public image available for logrotate, that's why we have created our own logrotate public image.
