图片名称，Docker-Compose中的Docker Syslog标签中的容器名称

由Docker Compose使用Syslog驱动程序创build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logging到Splunk等日志服务器，那么这太糟糕了。

我们如何改变标签的名称？

• 图像名称，包括版本
• 基于服务名称的容器名称
• 容器ID

这应该是这样的：

正如https://docs.docker.com/engine/admin/logging/log_tags/中所logging的那样，更改日志标记名称的方法可以使用在那里定义的variables…因此，您可以使用以下内容：

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

/ var / log / messages的输出如下（或者你的系统日志输出日志的地方）
