Kubernetes 如何在pod内使用“安装卷”；“kubectl”；CLI

我想使用

kubectl

CLI创建一个pod，它将在pod容器中装载hostpath

/etc/os release

，并显示

/etc/os release

文件的内容。 是否可以使用一个liner

kubectl

命令执行此操作

kubectl run -i --rm busybox --image=busybox --overrides='{
               "apiVersion": "v1",
               "spec": {
                  "containers": [
                     {
                        "image": "busybox",
                        "name": "busybox",
                        "command": ["cat", "/etc/os-release"],
                        "resources": {},
                        "volumeMounts": [
                           {
                              "mountPath": "/etc/os-release",
                              "name": "release"
                           }
                        ]
                     }
                  ],
                  "volumes": [
                     {
                        "name": "release",
                        "hostPath": {
                           "path": "/etc/os-release",
                           "type": "File"
                        }
                     }
                  ],
                  "dnsPolicy": "ClusterFirst",
                  "restartPolicy": "Never"
               },
               "status": {}
            }'
