k8s 创建容器一直 container creating

Question

1. K8S 创建容器后，查看pod状态，一直是 ContainerCreating
2. 创建容器命令

kubectl run nginx --image=10.0.2.22:5080/general/ubuntu-nginx:16 --command -- nginx

1. 下面是 kubectl describe 信息

[root@localhost ~]# kubectl describe pods nginx

Answer 1

可能是k8s的api服务没装好。

Answer 2

Error syncing 可能是容器本身的问题。可以用 kubectl logs nginx-xxx来看一下

Answer 3

我也遇到这个问题。

应该去看对应 pod 所在节点的 kubelet 的日志，就能看到错误原因了。
