Question

在minikube hyper-v机器中，我使用sawtooth config file进行了锯齿0的部署。

现在，当我检查运行的Pod时，它似乎有一些默认的Pod，但在尝试与kubernetes shell容器连接时。

C:\Users\Debo>kubectl get --all-namespaces
You must specify the type of resource to get. Use "kubectl api-resources" for a complete list of supported resources.

error: Required resource not specified.
Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).
See 'kubectl get -h' for help and examples

如果我了解您的用例，您正在尝试从名称空间中给定Pod列表中筛选出sawtooth-0 Pod，然后打开一个运行在其中您知道容器名称的容器的交互式会话。

所以要解决上述问题，我将问题中的锯齿配置文件作为附件，并启动了它的两个实例锯齿0和锯齿1以及几个虚拟吊舱，然后在Windows Power Shell上使用此命令过滤并连接到锯齿上的容器-0吊舱。

下面的所有操作都假设您需要在Windows Powershell上运行kubectl

PS C:\Users\winuser> kubectl get pods
NAME                          READY   STATUS    RESTARTS   AGE
busybox                       1/1     Running   0          4m18s
nginx                         1/1     Running   0          10m
sawtooth-0-7f584587cf-8jfwk   7/7     Running   0          19m
sawtooth-1-6ccd4494-kq24n     7/7     Running   0          18m

正在连接锯齿-0

PS C:\Users\winuser> kubectl exec -it $(kubectl get pods --no-headers -o custom-columns=":metadata.name" | findstr -i sawtooth-0) --container sawtooth-shell -- bash
