vitess基础镜像构建流程Centos

以下列出了构建vitess使用的Centos镜像的简单流程，由于较早基础版本是Centos7.2的，重新构建可以基于最新的Centos版本构建

1.基础镜像拉取

?

1 2 3

#拉取官方版本 docker pull centos:7.2.1511 官方镜像地址: https://hub.docker.com/_/centos/

2. 修改镜像源，可以选择阿里云的源地址或者内部源地址

CentOS-7.2-Base.repo

?

1 2 3 4 5 6 7 8 9 10 11 12

[CentOS] name=CentOS-7.2 - Base   #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - mirrors.aliyun.com failovermethod=priority baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/         http://mirrors.aliyuncs.com/centos/$releasever/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

3. 依赖程序安装

4 添加证书

?

1 2 3 4 5 6 7 8 9

#根据需要添加需要的证书，如果不需要就忽略 #切换到admin su admin     #添加信任证书 echo ssh-rsa xxxxxxxxxxxxxxxxxxxxxxxxxxxxx >> /home/admin/.ssh/authorized_keys       #修改证书授权文件权限 chmod 644 /home/admin/.ssh/authorized_keys

5. 提交镜像

?

构建完镜像之后直接获取镜像ID然后提交成基础镜像 提交后可以压缩镜像大小 docker commit 7541391ae047 vitesss/centos:7.2.1511
