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

supermin: writing supermin.d.1tcmz1m8/base.tar.gz
supermin: renaming supermin.d.1tcmz1m8 to supermin.d

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 .
