如何在google colab上运行docker

Question

我尝试使用我在另一个问题中找到的以下命令在google colab上安装docker：

%%shell     

sudo apt update -qq

sudo apt install apt-transport-https ca-certificates curl software-properties-common -qq

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" -y

sudo apt update -qq -y

sudo apt install docker-ce -y

docker

然后我尝试确认 docker 适用于以下内容：

!docker --version
!docker info
!docker run hello-world

给出以下信息和错误：

Docker version 24.0.2, build cb74dfc
Client: Docker Engine - Community
 Version:    24.0.2
 Context:    default
 Debug Mode: false
 Plugins:

  compose: Docker Compose (Docker Inc.)
    Version:  v2.18.1
    Path:     /usr/libexec/docker/cli-plugins/docker-compose

Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.

然后我尝试了各种命令来启动 docker 守护进程，例如 

!sudo systemctl start docker

给出了输出

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. See 'docker run --help'. System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

Answer 1

udocker

：

!pip install udocker

!udocker --allow-root install

然后您必须使用 

--allow-root

标志运行 udocker 命令。
