麒麟高级服务器操作系统 V10SP3 安装docker

# 配置阿里云 Centos8 镜像源，需要额外的一些依赖，而这些依赖在麒麟官方的源里面是没有的
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

# 配置阿里云 docker 镜像源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

# 修改 repo ，需要使用 centos 8的镜像源，若不修改无法使用。
echo "8" > /etc/yum/vars/centos_version
sed -i 's/$releasever/$centos_version/g' /etc/yum.repos.d/docker-ce.repo
sed -i 's/$releasever/$centos_version/g' /etc/yum.repos.d/CentOS-Base.repo

# 建立缓存
yum makecache

# 查看 Docker 版本
yum list docker-ce --showduplicates | sort -r

yum erase podman buildah

# 安装最新版
yum install docker-ce -y

#启动并设置开机自动启动
systemctl enable docker --now

#设置加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
     "max-concurrent-downloads": 10,
     "max-concurrent-uploads": 5,
     "default-shm-size": "1G",
     "debug": true,
     "experimental": false,
     "registry-mirrors":[
                "https://x9r52uz5.mirror.aliyuncs.com",
                "https://dockerhub.icu",
                "https://docker.chenby.cn",

                "https://dhub.kubesre.xyz"
        ]
}
EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

如果pull不了镜像
使用下边的镜像源


{
"registry-mirrors":[
    "https://daocloud.io"
 ]

}

8.配置加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
