[英]I tried running a pod with nginx image. I am inside my VM, but the pod is not getting created
[英]Pod with Debian image is getting created but container is continuously crashing
下面是我的 Pod 清单:
apiVersion: v1
kind: Pod
metadata:
name: pod-debian-container
spec:
containers:
- name: pi
image: debian
command: ["/bin/echo"]
args: ["Hello, World."]
下面是这个 Pod 的“describe”命令的 output:

下面是另一个output:

以下是我的问题:
RESTARTS
