如您所见,我希望我的日志可以在/app/logs/service.log 中找到,这就是我向我的 conf.d 提供的内容:

init_config:

在我的服务中,我使用 WinstonLogger 使用 JSON 格式的文件传输。
transports: [
new transports.File({
winston.format.json(),
filename: `${process.env.LOGS_PATH}/service.log`,
}),
]
process.env.LOGS_PATH = '/app/logs'
毕竟,在预期的/app/logs 文件夹中探索我的 pod 和 tail -f my service.log 时,我发现应用程序实际上按预期以 JSON 格式写入日志。
我的 DataDog 没有获取日志,并且它们没有显示在日志部分中..
注意::我不会在我的服务中装载任何卷..
我错过了什么?我应该将本地日志挂载到/var/log/pods/[service_name]/吗?
最佳答案
主要问题是您必须在应用程序容器和代理容器中安装该卷才能使其可用。这还意味着您必须在代理获取日志文件之前找到存储日志文件的位置。对每个容器执行此操作可能会变得难以维护且耗时。
另一种方法是将日志发送到 stdout
并让代理通过 Docker 集成收集它们。由于您将 logsConfigContainerCollectAll
配置为 true
,代理已配置为从每个容器输出收集日志,因此将 Winston 配置为输出到 stdout
应该可以正常工作。
