在 Ubuntu 18.04 上升级到 18.09 后 Docker CE 无法启动

当我尝试升级到 docker-ce 的最新版本 18.09.0~3-0~ubuntu-bionic 时，docker 无法启动，并出现找不到 devicemapper 插件的错误。

升级前一切都运行良好。当我恢复到 docker-ce 的先前版本 18.06.1~ce~3-0~ubuntu 时，它又可以正常工作了。任何想法都很好。

守护进程.json：

    "userns-remap": "lxd",
    "userland-proxy": false,
    "storage-driver": "devicemapper",
    "storage-opts": [

      "dm.use_deferred_removal=true",
      "dm.use_deferred_deletion=true"
    ]
}

使用 Ubuntu 18.04.1 LTS

感谢您花时间查看此内容。

答案1

已弃用的 devicemapper 已从 Ubuntu docker 包中删除由于代码移至 containerd。

在这个问题被修复之前，我建议将软件包固定到 18.06 版本。

cat > /etc/apt/preferences.d/docker  <<EOF
Package: docker-ce
Pin: version 18.06*
Pin-Priority: 1000
EOF

apt-get remove docker-ce runc docker containerd.io
apt-get install docker-ce thin-provisioning-tools
journalctl -xe | grep docker

答案2

删除我的存储选择和存储驱动程序配置后，我就能启动dockerd了。

根据@Ivan 链接中的信息，我删除了 docker-ce 并执行了autoremove。然后我重新安装了 docker-ce。安装后触发器尝试启动 dockerd，但失败了，但安装过程提供了journalctl -xe诊断问题的命令。

运行journalctl -xe显示错误消息，这让我怀疑是devicemapper。删除配置后dockerd可以正常启动。
