问题描述
Docker 在很多地方都提到了图像参考。但是，运行 docker images 命令将提供具有以下属性的图像列表：REPOSITORY，TAG，IMAGE ID，CREATED，SIZE-无参考。
Docker documentation mentions image reference in many places. However, running docker images command gives the list of images with the following properties: REPOSITORY, TAG, IMAGE ID, CREATED, SIZE - no reference. Is 'reference' a synonym for ID or digest, or something else?
推荐答案
docker图像参考是REPOSITORY的组合和TAG，格式为 REPOSITORY：TAG ，两者均以：分隔。因此，如果您的图片的存储库为 IMAGE1 并且标签为 latest ，则图像引用为 IMAGE1：latest 。映像参考的知识将帮助您通过运行以下命令按引用过滤docker映像列表：
The docker image reference is the combination of the REPOSITORY and TAG in this format REPOSITORY:TAG where they are both separated by :. So if you have an image with a REPOSITORY of IMAGE1 and a tag of latest the image reference would be IMAGE1:latest. The knowledge of an image reference would help you to filter by docker image list by reference by running:
docker images --filter=reference='myDocker*:*dev'
以上命令将返回所有存储库名称以 myDocker 开头且标签名称以 dev 结尾的docker镜像。
The above command will return all docker images that the repository name starts with myDocker and the tag name ends with dev.
