我正在尝试使用 kubectl get pods -o jsonpath=$JSONPATH 查询以下内容:
我尝试了以下 jsonpath:
JSONPATH={.items[*].status.containerStatuses[?(@.name=="some-appdeployment")].name}{"\t"}ready:{.items[*].spec.containers[?(@.name=="some-appdeployment")].phase}{"\n"}
还有这个:是否可以获取名称类似的项目，然后执行 grep '[some-appdeployment]' 来仅过滤那些容器
JSONPATH={.items[?(@.spec.containers[?(@.name=="some-appdeployment")])]}
最佳答案
如果您想要该输出，我的建议是执行如下命令:
kubectl get pods -n kube-system some-appdeployment -o jsonpath="Name: {.metadata.name} Status: {.status.phase}"
这对您的情况有用吗？
关于kubernetes - 如何获取特定 Pod 或容器的状态 : kubectl get pods using jsonpath，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45851945/
