作为一个opensuse的坚定fans，在此对docker官方文档未把opensuse及SLE平台的安装纳入文档，表示强烈不满。本文随手写了个简明手稿，供热爱opensuse的小朋友们参考。
对于连docker官网的网速我不想喷了，大家都懂。这里老老实实给出阿里云的。
拿来主义者直接复制即可，顺便把阿里云的packman一起给出，方便大家。
安装步骤如下：

镜像命令
docker images 查询本地镜像
1linux-famw:/home/neil # docker images 2REPOSITORY TAG IMAGE ID CREATED SIZE 3tomcat latest f3159377bac1 3 days ago 462MB 4linux-famw:/home/neil #
Repository 表示镜像的仓库源
TAG镜像的标签
IMAGE ID 镜像ID
CREATED：镜像创建时间
SIZE：镜像大小
查询命令还有其他参数：
-a 列出本地所有镜像。镜像是分层的，如要全部显示，需要添加这个参数。
-q 只显示镜像ID。组合使用-qa也可，特别是在删除镜像时，需要按照image id删除，这个时候会很有用。
--digest 显示镜像的摘要信息
--no-trunc 显示完整的镜像信息
docker search 搜索远程仓库镜像资源
docker search 某个镜像的名字
docker这个查找image资源的功能，和maven去mvn中央库下jar包有点类似。
但这里有个需要注意的地方是，虽然我们刚才为了下载更快，将本地的docker的仓库配置为阿里云，但是搜索操作还是会去https://hub.docker.com/搜索，然后再去阿里云上下载对应的镜像资源。
我们可以用命令搜索：
就像mvn中央库、github一样，全球的开发着和组织会将docker的镜像资源上传到docker hub上。比如我这里搜索tomcat的镜像image。
这里注意的是，OFFICAL列给出了这个docker image是不是官方提供的，AUTOMATED代表是不是自动构建的。

删除镜像
docker rmi 镜像名称
如果要删除的镜像正在被使用，则无法成功删除。这时候如果要强制删除，需要用命令：
docker rmi -f 镜像名称
删除多个镜像：
docker rmi -f 镜像名称1 镜像名称2
如果要带TAG，则：
docker rmi -f 镜像名称1:TAG1 镜像名称2:TAG2
如果要按照查询命令结果的镜像id列表来删除，可以这样：有点像sql子查询，和linux管道命令
docker rmi -f ${docker search -qa 镜像名称}
