如何为 traefik 启用 logrotation？

Question

如何为日志文件启用日志轮换，例如access.log.

这是内置的吗？

文档只说 "This allows the logs to be rotated and processed by an external program, such as logrotate"

Answer 1

似乎没有 logrotation built-in 所以我在挂载了 traefik_access.log 的主机上启用了 logrotation。

为了在 traefik 在 docker 容器中运行时工作，您必须卷挂载包含日志文件 (/opt/traefik/logs) 的目录，而不是日志文件本身 (/traefik_access.log).

volumes:
  - /opt/traefik/logs:/logs

我的 logrotate-config for traefik 1.7.4 运行在容器中，卷安装到“/opt/traefik/logs”：

/opt/traefik/logs/*.log {
  daily
  rotate 30
  missingok
  notifempty
  compress
  dateext
  dateformat .%Y-%m-%d
  create 0644 root root
  postrotate
  docker kill --signal="USR1" $(docker ps | grep traefik | awk '{print }')
  endscript
}

Answer 2

Log Rotation

Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal. This allows the logs to be rotated and processed by an external program, such as logrotate.

Answer 3

如果你是运行 Traefik 在 Docker 容器中，那么你可以这样做：

检查是否安装了 logrotate

logrotate --version

在 /etc/logrotate.d/

中创建文件

vi /etc/logrotate.d/traefik

放下面的脚本，不要忘记填写容器名称

/var/log/traefik/*.log {
  size 10M
  rotate 5
  missingok
  notifempty
  postrotate
    docker kill --signal="USR1" <container-name>
  endscript
}

运行!

logrotate /etc/logrotate.conf --debug 
logrotate /etc/logrotate.conf
