银河麒麟 v10 安装 docker

公司办公网络偶尔抽风，需要安装一个网络监控，恰好刚买了2台国产电脑，就想着在银河麒麟上部署一个smokeping，用docker方式，以下是部署记录，真是一波三折。

[root@lghd2000 ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
添加仓库自：https://download.docker.com/linux/centos/docker-ce.repo
[root@lghd2000 ~]# yum install -y docker-ce docker-ce-cli containerd.io
Docker CE Stable - aarch64 0.0 B/s | 0 B 00:00 
Errors during downloading metadata for repository 'docker-ce-stable':

发现系统会去找centos10的源，再次执行，系统又报libc.so.6的错误

[root@lghd2000 ~]# yum install -y docker-ce docker-ce-cli containerd.io

我们先解决centos10源的问题，目前centos最稳定版本是7系列，最高到7.9，8版本的稳定版本到8.5，之后就是stream版了，相对来看麒麟用centos7的源应该更好。所以我们可以修改docker-ce.repo文件，让它去从centos7版本里找包。

echo "7" > /etc/yum/vars/centos_version 
# 修改repo版本
sed -i 's/$releasever/$centos_version/g' /etc/yum.repos.d/docker-ce.repo

解决docker-ce.repo从centos7去找软件包后，我们再执行yum install -y docker-ce docker-ce-cli containerd.io安装docker，发现还是会报错，是因为centos7在银河麒麟里没有yum源，故我们还要配置一个centos7的源。

[root@lghd2000 ~]# yum install -y docker-ce docker-ce-cli containerd.io

添加阿里云centos7源，并修改repo文件里的系统版本为7。

#我这时是飞腾D2000处理器，需要用arm源
wget http://mirrors.aliyun.com/repo/Centos-altarch-7.repo -O /etc/yum.repos.d/CentOS-Base.repo
sed -i 's/$releasever/$centos_version/g' /etc/yum.repos.d/CentOS-Base.repo

#如果是x86架构的下载以下repo源文件
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

最后再执行docker安装，就正常了。

[root@lghd2000 ~]# yum install -y docker-ce docker-ce-cli containerd.io

注意：在银河麒麟V10 SP3版本中，操作系统自带的/usr/local/bin/runc 会与自安装的docker版本中的runc 冲突 ，可以先删除系统自有的runc(yum remove docker-runc）
