一.安装docker
1>.依赖的基础环境
64 bits CPU
Linux Kerner 3.10+(虽说Redhat 2.6.x内核也可以运行Docker，这是由于红帽为其打了很多补丁，但运行的稳定性极差，因此不推荐在生产环境中使用CentOS 6.x版本)
Linux Kernel cgroups and namespaces
2>.CentOS 7
“extras” repository仓库中存在docker的安装包，但是版本较低，因此我们不推荐使用CentOS自带的仓库软件包。
3>.下载docker-ce的仓库

2>.docker pull(下载docker镜像到本地，该命令等效于"docker image pull")
[root@node101.yinzhengjie.org.cn ~]# docker image push --help #查看该命令的帮助信息 Usage: docker image push [OPTIONS] NAME[:TAG] Push an image or a repository to a registry Options: --disable-content-trust Skip image signing (default true) [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# docker image pull nginx:1.14-alpine #注意：alpine版本表示专门用于构建容器小镜象的发行版，生产环境不推荐使用，学习阶段为了节省带宽可以这样玩。 1.14-alpine: Pulling from library/nginx bdf0201b3a05: Pull complete 3d0a573c81ed: Pull complete 8129faeb2eb6: Pull complete 3dc99f571daf: Pull complete Digest: sha256:485b610fefec7ff6c463ced9623314a04ed67e3945b9c08d7e53a47f6d108dc7 Status: Downloaded newer image for nginx:1.14-alpine docker.io/library/nginx:1.14-alpine [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# docker pull busybox #注意：busybox镜像可以理解为微小型的Linux虚拟机，据说安卓系统就用到了它。另外：如果我们只是指定仓库名称busybox，它默认回去下载busybox:latest这个tag版本。 Using default tag: latest latest: Pulling from library/busybox 7c9d20b9b6cd: Pull complete Digest: sha256:fe301db49df08c384001ed752dff6d52b4305a73a7f608f21528048e8a08b51e Status: Downloaded newer image for busybox:latest docker.io/library/busybox:latest [root@node101.yinzhengjie.org.cn ~]#
