基于 openGauss 学习 Docker
学习了一些开源产品，在潜移默化的发现，是时候该学习下 Docker 了，很多产品都制作了 Docker 镜像，想测试这些产品的时候，使用 Docker 安装就会显得特别方便。
简单介绍
openGauss 是一款高性能、高安全、高可靠的企业级开源关系型数据库。
opengauss 在开源后，云和恩墨第一时间制造了 docker 版本。
Docker 是基于 Go 语言开发的，开源项目
安装 Docker
需要注意 Docker 支持的平台：https://docs.docker.com/engine/install/
我的测试环境是 CentOS 7.6
# 1. Uninstall old versions 卸载旧版本
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
# 2. 需要的安装包，默认是国外的地址，很慢，这里使用阿里云的
yum install -y yum-utils
# 3. 设置镜像的仓库
yum-config-manager \
--add-repo \
https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
# 4. 更新软件包的索引
yum makecache fast
# 5. 安装 dokcer docker-ce是指社区版
yum install -y docker-ce docker-ce-cli containerd.io
安装的时候遇到一个小插曲，安装了 python3 没有修改 yum-config-manager 文件
[root@mogdb ~]# yum-config-manager \
> --add-repo \
> https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
File "/usr/bin/yum-config-manager", line 135
except yum.Errors.RepoError, e:

[root@mogdb ~]# vi /usr/bin/yum-config-manager # 换成 python2

[root@mogdb ~]# yum-config-manager \

Docker 为什么比 VM 快
Docker 有着比虚拟机更少的抽象层
Docker 利用的是宿主机的内核，vm 需要虚拟机操作系统
Docker 的常用命令
基于 openGauss 学习这些命令
基础命令
docker version # 显示 docker 的版本信息 docker info # 显示 docker 的系统信息，包括镜像和容器的数量 docker command --help # 帮助镜像命令
