rch*_*urt 9 linux ubuntu docker google-colaboratory
我正在尝试在 Google Colab 上运行 Docker，但遇到了一些问题。我按照在 Ubuntu ( https://docs.docker.com/engine/install/ubuntu/ )上安装 Docker 的步骤进行操作，这些步骤与其他人在 Digital Ocean ( https:// colab.research.google.com/drive/10OinT5ZNGtdLLQ9K399jlKgNgidxUbGP#scrollTo=9zp-VmLsws2r）。
我能够成功安装 Docker——我知道这一点，因为当我运行时，docker --version我得到了输出：Docker version 19.03.11, build 42e35e61f3，而且我从来没有收到任何错误，说命令docker不被识别。
但是当我尝试运行时sudo docker run hello-world --priveleged，我得到了输出：docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?..
我通过运行做了一些诊断sudo dockerd --debug，输出如下。我已经检查过，两者iptables和我的内核都已完全升级。运行whoami返回root。有些人建议重新启动内核，这也没有帮助。
这似乎是 Google Colab 特有的问题，但我无法弄清楚到底出了什么问题。有人有想法吗？如果您需要更多信息，请告诉我。
谢谢，
抢
这正是我在 Google Colab 中运行的代码：
%%shell
sudo curl -fsSL https://get.docker.com/ | sh
sudo usermod -aG docker root
sudo docker run hello-world --priveleged
sudo dockerd --debug
这是错误：

我很失望地发现 Google Colab 不支持 Docker，而且 Google 也没有计划支持它。
