ant-king-image (OCI镜像拉取，存储)

``` A Library For Download OCI Image

Example:

1、Downloade DockerHub Image

cripullimage("".tostring,"".tostring,"".tostring,imagename,image_version,docker:true).await.unwrap;

2、Download Registry Image

cripullimage(repositoriesurlip,username,password,imagename,imageversion,docker:false).await.unwrap;

3、运行

} ```

2、运行实例

``` [root@localhost container]# crictl --image-endpoint unix:///var/run/saodiseng.sock pull docker:ruilkyu/nginx:latest

Image is up to date for ruilkyu/nginx@sha256:bd877619f4ab21d0d2a26c622c0c51935d4da763203d83f542e39a4720d09bdc ```
