方法1

wget -O /etc/yum.repos.d/openEulerOS.repo https://repo.huaweicloud.com/repository/conf/openeuler_aarch64.repo

yum clean all

yum makecache

yum install -y docker

方法2

• 建立两个repo，docker-ce.repo和CentOS-Base.repo

  cd /etc/yum.repos.d

• 第一个文件

  vim docker-ce.repo

• 第二个文件

  vim CentOS-Base.repo

  # CentOS-Base.repo
  #
  # The mirror system uses the connecting IP address of the client and the
  # update status of each mirror to pick mirrors that are updated to and
  # geographically close to the client.  You should use this for CentOS updates
  # unless you are manually picking other mirrors.
  #
  # If the mirrorlist= does not work for you, as a fall back you can try the
  # remarked out baseurl= line instead.

• 建立缓存

  yum clean all
  yum makecache

• 安装docker-ce

  yum install docker-ce docker-ce-cli containerd.io -y

• 验证

  [root@openEuler yum.repos.d]# docker --version
  Docker version 20.10.8, build 3967b7d
  

• 配置自启动

  [root@openEuler yum.repos.d]# systemctl restart docker.service
  [root@openEuler yum.repos.d]# systemctl enable docker.service
  Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
