13.3.2.3. 使用 CLI 查看 OpenShift Virtualization pod 日志

流程

1. 运行以下命令，查看 OpenShift Virtualization 命名空间中的 pod 列表：

   $ oc get pods -n openshift-cnv

   例 13.1. 输出示例

   NAME                               READY   STATUS    RESTARTS   AGE
   disks-images-provider-7gqbc        1/1     Running   0          32m
   disks-images-provider-vg4kx        1/1     Running   0          32m
   virt-api-57fcc4497b-7qfmc          1/1     Running   0          31m
   virt-api-57fcc4497b-tx9nc          1/1     Running   0          31m
   virt-controller-76c784655f-7fp6m   1/1     Running   0          30m
   virt-controller-76c784655f-f4pbd   1/1     Running   0          30m
   virt-handler-2m86x                 1/1     Running   0          30m
   virt-handler-9qs6z                 1/1     Running   0          30m
   virt-operator-7ccfdbf65f-q5snk     1/1     Running   0          32m
   virt-operator-7ccfdbf65f-vllz8     1/1     Running   0          32m

2. 运行以下命令来查看 pod 日志：

   $ oc logs -n openshift-cnv <pod_name>

   注意

   如果 pod 无法启动，您可以使用 --previous 选项查看最后一次尝试的日志。

   要实时监控日志输出，请使用 -f 选项。
