docker（镜像命令）
接上篇：docker（帮助启动类命令）
1、docker images：列出本地主机上的镜像
[root@hadoop100 docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest feb5d9fea6a5 21 months ago 13.3kB
REPOSITORY：镜像的仓库源
TAG；镜像的标签版本号
IMAGE ID：镜像ID
CREATED：镜像创建时间
SIZE：镜像大小
同一个仓库源可以有不同的TAG（版本），我们使用REPOSITORY：TAG来定义不同的镜像，如果不指定一个TAG（版本），docker将默认使用latest（最新版）；
-- -q：只显示镜像ID -- -a：列出本地所有镜像（含历史映像层） [root@hadoop100 docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest feb5d9fea6a5 21 months ago 13.3kB [root@hadoop100 docker]# docker images -a REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest feb5d9fea6a5 21 months ago 13.3kB [root@hadoop100 docker]# docker images -q feb5d9fea6a5 [root@hadoop100 docker]# docker images -qa feb5d9fea6a5
2、docker search 镜像名称：在远程仓库中搜索某个镜像
2.1、docker search --limit 5 redis 只显示最前面的5条

NAME：镜像名称
DESCRIPTION：描述
STARS：点赞数
OFFICIAL：是否官方认证
AUTOMATE：是否自动构建
3、docker pull 镜像名称：在远程仓库拉取某个镜像
docker pull 镜像名称：默认拉取latest（最新版）
docker pull 镜像名称:TAG：拉取当前TAG版本的镜像
