Kubectl命令在Kubernetes中列出部署的Pod [英] Kubectl command to list pods of a deployment in Kubernetes

问题描述

是否可以使用kubectl仅列出属于部署的Pod? 目前，我这样做是为了获得豆荚:

Is there a way to use kubectl to list only the pods belonging to a deployment? Currently, I do this to get pods:

kubectl get pods| grep hello

但是，当我有兴趣仅了解给定部署的Pod时，获得所有Pod似乎是过大的选择.我使用此命令的输出来查看所有Pod的状态，然后可能执行其中的一个.

But it seems an overkill to get ALL the pods when I am interested to know only the pods for a given deployment. I use the output of this command to see the status of all pods, and then possibly exec into one of them.

我也尝试过kc get -o wide deployments hellodeployment，但是它不显示Pod名称.

I also tried kc get -o wide deployments hellodeployment, but it does not print the Pod names.

推荐答案

有一个选择器的窗格中的noreferrer>标签. a>在部署中.这就是部署对其吊舱进行管理的方式.例如，对于标签或选择器app=http-svc，您可以执行类似的操作，并避免使用grep并列出所有吊舱(当吊舱数量变得非常大时，此功能将非常有用):

There's a label in the pod for the selector in the deployment. That's how a deployment manages its pods. For example for the label or selector app=http-svc you can do something like that this and avoid using grep and listing all the pods (this becomes useful as your number of pods becomes very large):

$ kubectl get pods -l=app=http-svc

或

$ kubectl get pods --selector=app=http-svc
