Docker containers log rotator for kubernetes

This simple tool was created to rotate docker container log files in kubernetes, because by default rotation do not happen and after awhile log file size might increase significally not allowing you to schedule storage anymore.

It works as daemonset to cover all possible nodes, mounts '/var/lib/docker/containers' directory launch simple log-cleanup.sh script and rotates logs.

Installation

git clone https://github.com/PlumTreeSystems/docker-logrotate.git
cd docker-logrotate
cd helm
helm install -n [namespace] [name] .

Logs are being rotated by default once every Tuesday (can be changed in values.yaml file)

This tool by default rotates logs once every Tuesday, but you can easily change that in helm values file by providing casual cron expression. For example: 0 7 * * 2 - it means it will be executed every Tuesday at 7AM

MUST KNOW

This is for self-managed kubernetes instances. It was NOT tested on AWS / Azure / GCloud etc
