- The container runtime needs to support the image volumes feature
|
||
- You need to exec commands in the host
|
||
- You need to be able to exec into pods
|
||
- You need to enable the `ImageVolume` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/)

- 容器运行时需要支持镜像卷特性
|

- 你需要能够在主机上执行命令
|

- 你需要能够进入 Pod 执行命令
|

- 你需要启用 `ImageVolume`

## Run a Pod that uses an image volume {#create-pod}
|
||
|
||
An image volume for a pod is enabled setting the `volumes.[*].image` field of `.spec`
|
||
to a valid reference and consuming it in the `volumeMounts` of the container. For example:

|
||
## 运行使用镜像卷的 Pod {#create-pod}
|
||
|
||
为 Pod 启用镜像卷的方式是：在 `.spec` 中将 `volumes.[*].image`
|
||
字段设置为一个有效的镜像并在容器的 `volumeMounts` 中消费此镜像。例如：
|
||
|
||
{{% code_sample file="pods/image-volumes.yaml" %}}
|
||
|
||
<!--
|
||
1. Create the pod on your cluster:
|
||
-->
|
||
1. 在你的集群上创建 Pod：
|
||
|
||
```shell
|
||
kubectl apply -f https://k8s.io/examples/pods/image-volumes.yaml
|
||
```
|
||
|
||
<!--
|
||
1. Attach to the container:
|
||
-->
|
||
2. 挂接到容器：
|
||
|
||
```shell
|
||
kubectl attach -it image-volume bash
|
||
```
|
||
|
||
<!--
|
||
1. Check the content of a file in the volume:
|
||
-->
|
||
3. 查看卷中某个文件的内容：
|
||
|
||
```shell
|
||
cat /volume/dir/file
|
||
```
|
||
|
||
<!--

cat /volume/file
