如何在kubernetes集群中拖尾所有日志

问题描述

我尝试了以下命令:

kubectl logs --tail

我收到此错误/帮助输出:

I got this error/help output:

Error: flag needs an argument: --tail


Aliases:
logs, log

Examples:
  # Return snapshot logs from pod nginx with only one container
  kubectl logs nginx

  # Return snapshot logs for the pods defined by label app=nginx
  kubectl logs -lapp=nginx

  # Return snapshot of previous terminated ruby container logs from pod web-1
  kubectl logs -p -c ruby web-1

  # Begin streaming the logs of the ruby container in pod web-1
  kubectl logs -f -c ruby web-1

  # Display only the most recent 20 lines of output in pod nginx
  kubectl logs --tail=20 nginx

  # Show all logs from pod nginx written in the last hour
  kubectl logs --since=1h nginx

  # Return snapshot logs from first container of a job named hello
  kubectl logs job/hello

  # Return snapshot logs from container nginx-1 of a deployment named nginx
  kubectl logs deployment/nginx -c nginx-1

嗯，我只想查看所有日志，这不是一件常见的事情吗?如何跟踪集群的所有日志?

ummm I just want to see all the logs, isn't this a common thing to want to do? How can I tail all the logs for a cluster?
