在WINDOWS 10 WSL1 的子系统下完美解决DOCKER的命令问题

在Windows 10 （1909）安装了子系统ubuntu-20.04与windows-docker-2.3.0.3,在WSL1命令行下执行“docker ps”会出现如下问题：

The command 'docker' could not be found in this WSL 1 distro.
We recommend to convert this distro to WSL 2 and activate
the WSL integration in Docker Desktop settings.
 
See https://docs.docker.com/docker-for-windows/wsl/ for details.

解决方案

首先在docker setting上设置如下图（红圈钩选中部份）

 

 打开Ubuntu Shell,执行以下命令：

wsl

sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
 
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
 
sudo apt remove gpg
 
sudo apt install gnupg1
 
sudo apt install software-properties-common
 
sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
 
sudo apt-get -y update

#先查询有哪些docker版本
apt-cache madison docker-ce

#安装最新版
sudo apt-get install -y docker-ce

#安装指定版要，比如安装5:19.03.6~3-0~ubuntu-bionic版本,-y参数有示非交互安装，有交互的时候自动传y参数。
sudo apt-get install -y docker-ce=5:19.03.6~3-0~ubuntu-bionic
 
echo "export DOCKER_HOST=tcp://localhost:2375" >> ~/.bashrc && source ~/.bashrc

然后重启windows的Docker,
