wsl can install docker. The installation method: 1. Install and configure wsl; 2. Download and install docker for windows from the official website; 3. Install docker-compose through pip.

The operating environment of this article: Ubuntu18.06 system, Docker-CE version, Dell G3 computer.

wsl Can docker be installed?

Installing docker under wsl

docker for windows itself can be used directly, but there are still many shortcomings, such as: permission issues and no docker.sock file , file encoding issues, etc. The wsl that comes with win10 can solve these problems perfectly.

Install wsl

First open for Linux in Programs and Features->Turn windows features on and off Windows Subsystem

Then open the Microsoft App Store, search for Ubuntu directly, select the 18.06 version of ubuntu to install

wsl configuration

First configure the Alibaba Cloud image, vim /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

Then update the source

apt update

By default, the windows directory will automatically mount (mount) to the /mnt directory in wsl, but this It will cause relative path problems with docker later. So modify the configuration file /etc/wsl.conf

[automount]
root = /
options = "metadata,umask=22,fmask=11"

so that the c drive in Windows is automatically mounted to the /c/ directory in wsl, and the d drive is automatically mounted to /d in wsl. / directory

Install docker for windows

Go directly to the official website to download and install.

When installing, because we need to use docker in wsl, which is linux container, remember not to select windows container.

After installation, first configure the accelerator. Currently, I use Alibaba Cloud and daocloud accelerators, which are very fast. Just go to the corresponding website and follow the instructions.

When developing, you need to share the code on the physical machine and the code files in the container, so you need to configure the shared drive letter in Shared Drives. Which disk your code is in, then choose which disk to share

Installing docker in wsl

If you directly use apt to install docker, it will not be the latest version, so refer to the official documentation Install the latest version of docker (https://docs.docker.com/install/linux/docker-ce/ubuntu/)

That is:

sudo apt-get remove docker docker-engine docker.iosudo apt-get updatesudo apt-get install \
    apt-transport-https \
    ca-certificates \    curl \
    software-properties-commoncurl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -sudo apt-key fingerprint 0EBFCD88sudo add-apt-repository \   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \   $(lsb_release -cs) \
   stable"sudo apt-get updatesudo apt-get install docker-ce

Try to execute the docker command:

docker version

The results are as follows:

Client:
 Version:      18.03.1-ce
 API version:  1.37
 Go version:   go1.9.5

  Experimental: false

OK, but what if I run it again?

docker run busybox

At this time, it will prompt that the docker daemon is not running. Then execute:

sudo service docker start

Although you see is starting, docker still cannot run.

At this point, you need to open General->Expose daemon on tcp://localhost:2375 without TLS

in docker for windows and then execute it in wsl :

export DOCKER_HOST=tcp://localhost:2375

Then you can start running.

In addition, docker-compose will not be installed by default. If you install docker-compose through apt, it will not It will be the latest version, but the one installed through pip is the latest version, so:

sudo apt install python-pipsudo pip install docker-compose

Test:

docker-compose version
