子系统安装Docker

安装Docker

在本地机器上创建docker.sh 脚本，并将如下内容放入脚本中。

#!/bin/bash
echo ~~~~~~~~~~~~~~Start Install~~~~~~~~~~~~~~
#Set up the repository
sudo apt install ca-certificates curl gnupg lsb-release

echo ~~~~~~~~~~~~~~ Add Docker official GPG key~~~~~~~~~~~~~~

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

echo ~~~~~~~~~~~~~~Set up the repository~~~~~~~~~~~~~~

echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

echo ~~~~~~~~~~~~~~Start Install Docker Engine~~~~~~~~~~~~~~
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

echo ~~~~~~~~~~~~~~Configure Docker daemon~~~~~~~~~~~~~~
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://jxmh3d66.mirror.aliyuncs.com"]
}
EOF

echo ~~~~~~~~~~~~~~Set up non-root user~~~~~~~~~~~~~~
sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

echo ~~~~~~~~~~~~~~Start Docker service~~~~~~~~~~~~~~
sudo service docker start

进入子系统Ubuntu中，然后切换到docker.sh目录(在子系统访问主系统是挂载在/mnt下，如：子系统访问F盘，就是/mnt/f),然后执行该脚本。

脚本说明：

可以将脚本中的： "https://jxmh3d66.mirror.aliyuncs.com"替换为其他Docker镜像地址。
