华为鲲鹏麒麟安装docker
安装 Docker-ce
下载二进制docker
官网下载地址：https://download.docker.com/linux/static/stable/aarch64/
解压下载好的压缩包
tar -zxvf docker-20.10.9.tgz
移动解压出来的二进制文件到 /usr/bin 目录中
mv docker/* /usr/bin/
测试启动
dockerd
添加 systemd
添加 docker 的 systemd 服务脚本至 /usr/lib/systemd/system/

重载 systemd 配置文件
systemctl daemon-reload
创建 docker 组
groupadd docker
如不创建 docker 组在通过 systemctl 启动时会报错如下
Dependency failed for Docker Application Container Engine.
Job docker.service/start failed with result \'dependency\'.
启动 docker 服务
systemctl start docker
systemctl enable docker
修改 docker 配置文件并查看安装好的 docker 基本信息
mkdir -p /etc/docker/
cat > /etc/docker/daemon.json <<\'EOF\'
{
"registry-mirrors": ["https://xxxxxxxxxxxxxxxxxxxxxx.mirror.swr.myhuaweicloud.com"]
}

重启 docker 服务
systemctl restart docker
查看 docker info
