如何让 kubectl 日志与日志一起输出 pod 名称？

Question

I'm using the handy kubectl logs -l label=value command to get log from all my pods matching a label. I want to see which pod outputted what log, but only the log text is displayed. Is there a way to control the log format, or a command argument which will let me do this?

Answer 1

使用很棒的kubetail脚本

Answer 2

我使用 stern 显示来自所有 pod https://github.com/wercker/stern 的日志。

Answer 3

kubectl现在有一个--prefix选项，允许您在日志消息之前添加 pod 名称的前缀。

Answer 4

As simple as this:

for pod in $(kubectl get po -l key=value -oname); do echo $pod; kubectl logs $pod; done;

this will fetch the names of the pods by their label, then will one by one print the logs after writing the name of the pod. So, it will look like something like this:

pod1
log
log
log
pod2
log
log
log
...
podn
log
log
log
