引言

由于默认的Docker Hub镜像仓库是国外的，下载镜像较慢甚至中途卡死，所以配置阿里镜像加速器解决这一问题提高速度，管理你的镜像和拉取别人的镜像 。
推荐安装1.10.0以上版本的Docker客户端，参考文档 docker-ce

获取阿里云镜像加速

  • 阿里云镜像加速地址：点击获取

    配置镜像加速

  • 针对Docker客户端版本大于 1.10.0 的用户
    您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

  • 创建docker配置文件夹

    1. sudo mkdir -p /etc/docker

  • 将加速地址写入配置daemon.json

    1. sudo tee /etc/docker/daemon.json <<-'EOF'
    2. {
    3. "registry-mirrors": ["https://*****.mirror.aliyuncs.com"]
    4. }
    5. EOF

    配置自己获取的阿里云加速地址信息

  • 重新加载配置

    1. sudo systemctl daemon-reload

  • 重启docker使配置生效

    1. sudo systemctl restart docker

  • 查看配置生效

    1. docker info


    可以看到末尾Registry Mirrors 新增阿里云加速地址 ``` Client: Debug Mode: false

至此docker加速器配置完成
