docker| 删除镜像报错

执行docker rmi $(docker images -aq)时出现：

Error response from daemon: conflict: unable to delete b023f9be0771 (must be forced) - image is referenced in multiple repositories

当我再执行docker images时，发现相同的Image ID有两个不同的Tag。

docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE

使用仓库加Tag的方式来删除：

docker rmi hyperledger/fabric-peer:latest 

之后再用docker rmi $(docker images -aq)来删除。
