由Docker Compose使用Syslog驱动程序创建的Docker容器生成的日志使用以下格式“docker / Container_ID”。

如果您将这些日志带到Splunk等日志服务器上，这太糟糕了。

我们如何更改标签的名称？

图片名称，包括版本
基于服务名称的容器名称
容器ID

那应该是这样的：

Answer 1

正如https://docs.docker.com/engine/admin/logging/log_tags/所述，更改日志标记名称的方法可以使用那里定义的变量......所以，你可以使用以下内容：

  log_driver: syslog
  log_opt:
    tag: "{{.ImageName}}/{{.Name}}/{{.ID}}"

/ var / log / messages 的输出如下（或系统日志输出记录到的任何地方）

Answer 2

对于当前的docker-compose（1.24.1）语法，另一个答案已过时。要设置必要的日志记录，您需要在docker-compose.yaml文件中为服务使用以下内容：

logging:
  driver: syslog
  options:
    tag: "{{.ImageName}}/{{.Name}}/{{.ID}}"

Docker-Compose中Docker Syslog标记中的映像名称，容器名称
