我正在尝试使用
kubectl get pods -o jsonpath=$JSONPATH我尝试过以下jsonpath：
JSONPATH={.items[*].status.containerStatuses[?(@.name=="some-appdeployment")].name} {“”} 准备好： {.items[*].spec.containers[?(@.name=="some-appdeployment")].phase} {” “}
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")])]}
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？
以下命令对我有用，请尝试一下。
kubectl get pods <pod-name> --no-headers -o custom-columns=":status.phase"
我在下面使用的 openshift 效果非常好
oc get pods -l deploymentconfig='db' -o jsonpath='{.items[*].status.containerStatuses[0].ready}'
有点难看，但至少这不是想要的（如 Javier Salmeron 所做的），而是 Pod 的真实状态：
kubectl -n MYNAMESPACE describe pods MYPOD | grep ^Status: | head -1 | awk '{print $2}' | tr -d '\n'说明：我们对 Pod 进行描述，然后 grep 以
Status:我对这个问题的 2 美分，不要将 POD 状态与 Container 状态混为一谈（它们确实是相关的）。
PendingRunningSucceededFailed您可以使用以下方法检查 Pod 的状态（这是一个 PodStatus 对象）：
# status for pods from all namespaces use -n instead of -A for the desired namespace
kubectl get po -A -o jsonpath='{.items[*].status}'
# it's rather verbose so you can pipe it to jq (if installed)
kubectl get po -A -o jsonpath='{.items[*].status}' | jq .
statusphasePendingRunningSucceededFailed Unknow。您可以检查与 Running# check phase for pods in all namespaces
kubectl get po -A --field-selector=status.phase!=Running
当 Pod 被删除时，某些
TerminatingkubectlTerminatingPod内的容器状态，可以具有以下值之一：
Waiting RunningTerminated# check container related info use -n instead of -A for the desired namespace
kubectl get po -A -o jsonpath="{.items[*].status.containerStatuses[*].state}"
jq对于 Pod 状态，唯一的答案（Pod 可以正在运行但尚未准备好！）：
kubectl get pods -l <key=val> -o 'jsonpath={..status.conditions[?(@.type=="Ready")].status}'
对于单个容器状态（需要为“true”）：
kubectl get pod <pod_name> --output="jsonpath={.status.containerStatuses[*].ready}" | cut -d' ' -f2
kubectl get pods -n deployNamespace -ojson | jq '.spec.status.phase'
您将安装 jq。
status.phase 将返回 pod 状态而不是容器状态。但是 kubectl get pod 返回 pod 容器的状态，因此如果 pod 内的容器出现 crashloopbackoff 错误，它将在状态中显示这一点。
一个可能的解决方案是检查容器状态。 我已经定制了 @javier 评论来获得这个。我希望它有帮助
kubectl get pods -o jsonpath="名称：{.items[*].metadata.name} 阶段：{.items[*].status.phase} 容器状态：{.items[*].status.containerStatuses[*] .state}”
通常 Pod 名称后跟唯一的哈希/ID。 为了专门针对名称，请使用 --selector 标志：
kubectl get pods -n deployNamespace --selector=name=yourAppName -o jsonpath="{.items[*].status.phase}"
此示例将仅输出状态阶段。
我也遇到过同样的情况，我对 pod 特定的东西有一些价值，我编写了一个小的 bash 脚本来做到这一点。您可以使用以下命令获取它：
kubectl get pods -n ${NAMESPACES} | grep -dw ${POD_SPECIFIC_VALUE} | cut -w -f3
另一种选择
kubectl 描述 pod podname | grep -i 状态：
