核心功能

• 日志轮转管理：按自定义配置对指定日志文件执行轮转、保留、压缩等操作
• 定时调度：通过CRON_SCHEDULE设置日志轮转任务的执行频率
• 灵活适配：支持独立运行或作为Kubernetes Sidecar配合服务处理日志

使用场景

• 独立部署：处理本地或共享卷中的日志文件，实现自动轮转
• Kubernetes Sidecar：与Traefik等服务搭配，作为辅助容器管理服务日志

配置说明

部署示例

独立运行

sh
docker run -it --rm \
  --env CRON_SCHEDULE='* * * * *' \
  -v $(pwd)/example/logrotate.conf:/etc/logrotate.conf:ro \
  -v $(pwd)/example/logs:/logs \
  skymatic/logrotate
# 日志写入example/logs/example.log，每达到1MiB时触发轮转

Kubernetes Sidecar（Traefik示例）
