如何获得kubernetes中命名空间中所有容器的自定义列资源限制和请求

我试过这个：

k get po -n myns -o=custom-columns=NAME:.spec.containers.name,MEMREQ:.spec.containers.resources.requests.memory,MEMLIM:.spec.containers.resources.limits.memory,CPUREQ:.spec.containers.resources.requests.cpu,CPULIM:.spec.containers.resources.limits.cpu

但它给了我这个：

    NAME     MEMREQ   MEMLIM   CPUREQ   CPULIM
    <none>   <none>   <none>   <none>   <none>
    <none>   <none>   <none>   <none>   <none>
    <none>   <none>   <none>   <none>   <none>
    <none>   <none>   <none>   <none>   <none>
    <none>   <none>   <none>   <none>   <none>
    <none>   <none>   <none>   <none>   <none>
    <none>   <none>   <none>   <none>   <none>

NAME MEMREQ MEMLIM CPUREQ CPULIM

注意，

容器

是一个列表，因此您必须为所有容器提供索引或

*

下面是我的环境中的一个示例，您可以调整命令的其余部分

kubectl get po -o=custom-columns=NAME:.spec.containers[*].name
NAME
nginx
nginx



kubectl get po -o=custom-columns=NAME:.spec.containers.name
NAME
<none>
<none>

---

这个问题可能更适合或。

kubectl get pod my-nginx-66b6c48dd5-gq6vd  -o jsonpath='{.spec.containers}'
