一 使用supermin5命令（若命令不存在则自己安装）构建centos7系统的docker镜像，镜像名称为centos-7，镜像预装yum、net-tools、initscripts和vi命令，构建完成后提交镜像仓库上传操作，并查看此镜像。
1 针对于这个案例，我们首先安装我们的supermin5 工具
[root@server media]# yum install -y supermin5 Loaded plugins: fastestmirror centos | 3.6 kB 00:00:00 docker | 2.9 kB 00:00:00 Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package supermin5.x86_64 0:5.1.10-1.2.el7 will be installed --> Processing Dependency: yum-utils for package: supermin5-5.1.10-1.2.el7.x86_64 --> Running transaction check ---> Package yum-utils.noarch 0:1.1.31-34.el7 will be installed --> Processing Dependency: python-kitchen for package: yum-utils-1.1.31-34.el7.noarch --> Running transaction check ---> Package python-kitchen.noarch 0:1.1.1-5.el7 will be installed --> Processing Dependency: python-chardet for package: python-kitchen-1.1.1-5.el7.noarch --> Running transaction check ---> Package python-chardet.noarch 0:2.2.1-1.el7_1 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================= Package Arch Version Repository Size ======================================================================================================================================= Installing: supermin5 x86_64 5.1.10-1.2.el7 centos 574 k Installing for dependencies: python-chardet noarch 2.2.1-1.el7_1 centos 227 k python-kitchen noarch 1.1.1-5.el7 centos 267 k yum-utils noarch 1.1.31-34.el7 centos 113 k Transaction Summary ======================================================================================================================================= Install 1 Package (+3 Dependent packages) Total download size: 1.2 M Installed size: 4.3 M Downloading packages: --------------------------------------------------------------------------------------------------------------------------------------- Total 49 MB/s | 1.2 MB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : python-chardet-2.2.1-1.el7_1.noarch 1/4 Installing : python-kitchen-1.1.1-5.el7.noarch 2/4 Installing : yum-utils-1.1.31-34.el7.noarch 3/4 Installing : supermin5-5.1.10-1.2.el7.x86_64 4/4 Verifying : python-kitchen-1.1.1-5.el7.noarch 1/4 Verifying : supermin5-5.1.10-1.2.el7.x86_64 2/4 Verifying : yum-utils-1.1.31-34.el7.noarch 3/4 Verifying : python-chardet-2.2.1-1.el7_1.noarch 4/4 Installed: supermin5.x86_64 0:5.1.10-1.2.el7 Dependency Installed: python-chardet.noarch 0:2.2.1-1.el7_1 python-kitchen.noarch 0:1.1.1-5.el7 yum-utils.noarch 0:1.1.31-34.el7 Complete!
2 下面开始使用supermin5制作我们所需要的镜像所需的安装包。
下面命令是准备要安装的软件包并保存在supermin.d目录下

3 下面开始构建我们的镜像。下面命令是根据上一步准备的安装包目录制作隔离的环境，并保存在appliance.d目录下
[root@server media]# supermin5 -v --build --format chroot supermin.d -o appliance.d supermin: version: 5.1.10 supermin: rpm: detected RPM version 4.11 supermin: package handler: fedora/rpm supermin: build: supermin.d supermin: build: visiting supermin.d/base.tar.gz type gzip base image (tar) supermin: build: visiting supermin.d/packages type uncompressed packages supermin: build: 135 packages, including dependencies supermin: build: 26059 files supermin: build: 12875 files, after removing unreadable files supermin: build: 12875 files, after matching excludefiles supermin: build: 12875 files, after adding hostfiles supermin: build: 12913 files, after munging supermin: renaming appliance.d.idqctht6 to appliance.d
4 如果要使用yum安装软件包，可以执行我们的下面的命令
[root@server media]# echo 7 > appliance.d/etc/yum/vars/releasever
5 如果要上网，则要执行我们下面的命令
[root@server media]# cp /etc/resolv.conf appliance.d/etc/
6 然后开始构建我们的镜像
[root@server media]# tar --numeric-owner -cpf centos-7.tar -C appliance.d/ .
7 开始导入我们的容器
[root@server media]# cat centos-7.tar | docker import - 10.0.3.137:5000/centos-8888 sha256:d06398dcf03fc1d3ef0be50dc5759948775933adc177237644fb5510981c3990
8 使用docker命令查看我们的容器
[root@server media]# docker images | grep centos-8888 10.0.3.137:5000/centos-8888 latest d06398dcf03f 4 minutes ago 260.6 MB [root@server media]#
以上简单步骤便是我们的使用supermin5 制作我们的镜像的过程
二 编写以上题构建的centos-7镜像为基础镜像，构建数据库服务，Dockerfile要求删除镜像的yum源，使用当前系统的yum源文件，完成后安装mariadb服务，使用mysql用户初始化数据库，添加MYSQL_USER=xiandian、MYSQL_PASS=xiandian环境变量，要求数据库支持中文，暴露端口3306，容器开机运行mysld_safe命令，完成后启动创建的镜像并查询Dockerfile文件，进入容器查看容器的数据库列表.
1 下面编写我们的dockerFile文件
[root@server dockerfile]# vi Dockerfile FROM 10.0.6.126:5000/centos-7 MAINTAINER Xiandian RUN rm -fv /etc/yum.repos.d/* ADD local.repo /etc/yum.repos.d/ RUN yum install -y mariadb-server RUN mysql_install_db --user=mysql ENV LC_ALL en_US.UTF-8 ENV MYSQL_USER xiandian ENV MYSQL_PASS xiandian EXPOSE 3306 CMD mysqld_safe
2 构建我们的docekr镜像文件，这里要留意下，我们的环境变量的USER 和 PWD
下面是查找路径的截图。这里的环境变量是根据我们的数据库Container的API接口来指定的
下面开始构建我们的centos
[root@server dockerfile]# docker build -t 10.0.3.137:5000 /centos .
