如何使用Shell脚本等待Kubernetes Pod列表成功完成 [英] How to wait until Kubernetes list of pods are successful using shell script

问题描述

我试图找到一个命令或示例shell片段，在这里我可以等到Kubernetes Pod列表成功完成.我已经检查了答案，但是它没有给出任何输出.有人可以指导我或建议一种方法吗，我对kubernetes完全陌生.

I am trying to find a command or a sample shell snippet where I can wait until the list of Kubernetes pods is successful. I have checked the answer but it was not giving any output. Can someone guide me or suggest an approach, I am completely new to kubernetes.

kubectl -n test-ns get jobs -w

NAME     DESIRED   SUCCESSFUL   AGE
test-1    1         1            2d
test-2    1         1            2d
test-3    1         1            2d
test-4    1         1            2d


until kubectl get jobs -n test-ns  -o jsonpath='{.status.conditions[?(@.type=="Complete")].status}' | grep True ; do sleep 1 ; done

这没有给出任何输出

推荐答案

要等到pod运行起来，请检查"condition = ready"并按应用标签进行过滤，例如:

To wait until your pods are running, check for "condition=ready" and filter by app label, for example:

$ kubectl wait --for=condition=ready pod -l app=netshoot 
pod/netshoot-58785d5fc7-xt6fg condition met
