查看鏡像
docker images [鏡像名稱]
docker image ls [鏡像名稱]#作用：列出本地鏡像 # docker images為docker image ls的簡寫，可以跟鏡像名稱，比如可以搜出Ubuntu的不同版本，命令格式如下 docker images [鏡像名稱] docker image ls [鏡像名稱] #命令演示： qwe@ubuntu:~$ docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu latest d70eaf7277ea 10 days ago 72.9MB hyperledger/caliper 0.4.0 6491b4ec891d 4 weeks ago 356MB hello-world latest bf756fb1ae65 10 months ago 13.3kB # dockers images和docker image ls效果相同 qwe@ubuntu:~$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu latest d70eaf7277ea 10 days ago 72.9MB hyperledger/caliper 0.4.0 6491b4ec891d 4 weeks ago 356MB hello-world latest bf756fb1ae65 10 months ago 13.3kB #docker images -a 列出所有的本地的images(包括已刪除的鏡像記錄) qwe@ubuntu:~$ docker image ls -a REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu latest d70eaf7277ea 10 days ago 72.9MB hyperledger/caliper 0.4.0 6491b4ec891d 4 weeks ago 356MB hello-world latest bf756fb1ae65 10 months ago 13.3kB注：
- REPOSITORY：鏡像的名稱
- TAG：鏡像的版本標簽，用來區分不同發行版本，如果不指定具體標記,默認使用latest標記信息
- IMAGE ID：鏡像的ID，唯一標識了鏡像，如果ID相同,說明是同一鏡像。
- CREATED：鏡像是什么時候創建的
- SIZE：大小
