Docker медленно работает на windows

CHALLENGE: Incorrectly configured Docker leads to slow Docker on Windows performance 

SOLUTION: Run Docker Windows from Ubuntu 20.04 LTS with WSL2 enabled 

Docker Windows performance problems 

If you want to use Docker on Windows, the Docker Desktop application needs to be installed. However, installation with default settings usually causes Docker performance poor and not very fast.  

One of the more common problems for Developers that use Windows is that the projects with Docker configuration work really slowly, to a point when sometimes a single browser request needs to wait 30-60 seconds to be completed. This is obviously a problem, one that negatively affects project progression and generally makes the life of developers more difficult. 

Why is Docker slow on Windows?  

The root of the issue is that Windows 10 is (was) using WSL (Windows Subsystem for Linux), which is a layer between Windows and Linux. Communication between these two (Hard Drive operations) can be quite slow 

Solution for slow Docker on Windows performance improvement 

The suggested solution is: 

• use WSL 2 in Windows 10 

• and start Docker directly from Ubuntu in Windows 

Check out the step-by-step tutorial below. The “WSL 2” feature, released as Windows Update in mid 2020, was designed to increase file system performance and support full system call compatibility. Properly configured Docker and Windows WSL2 will give you really good performance in terms of speed. 

Explanation: Windows Subsystem for Linux (WSL) 2 introduces a significant architectural change as it is a full Linux kernel, allowing Linux containers to run natively without emulation. To get the best out of the file system performance when bind-mounting files, we recommend storing the source code in the Linux file system, rather than the Windows file system. 

Step 1: ENABLE WSL2 on Windows 

A. Enable WSL 2 on your Windows 
B. Install Linux on Windows 10 (Ubuntu 20.04 LTS from Microsoft store) 
C. Enable WSL 2 on Ubuntu 20.04 
D. Install Docker Desktop 
E. Enable WSL 2 for Docker

Step 2: Install SSH on Ubuntu 

We want to enable SSH connection to Ubuntu and we will be using it for local files’ “deployment”. Our goal here is: 

– We have a GIT project cloned on the main Windows hard drive (SSD) 
– We’re developing using PHPStorm 
– PHPStorm Files’ deployment is configured in a way to automatically send files to Ubuntu. 
– With this setup, we will instantly see the changes to our code in the browser. 

How to configure SSH on Ubuntu: 
https://linuxize.com/post/how-to-enable-ssh-on-ubuntu-18-04/ 

Step 3: Configure PHPStorm Deployment 

A. File / Settings / Build, Execution, Deployment – Deployment 
B. Click + (to add a new deployment config) – choose SFTP 
C. Fill in ‘SSH configuration’ 
– Host: your Ubuntu public IP 
(to find the proper IP address, type the following command in your Ubuntu: ip a) 
– User name: your ubuntu username 
– Authentication type: Password 
– Password: your ubuntu pass 
D. Set proper directories mapping in: Deployment / Mappings 
E. Deployment / Options: 
– find the option ‘Upload change files automatically to the default server’ and set to ‘Always’ 

Step 4: ssh to Ubuntu, run Docker 

A. Open your SSH Client (ex: Cmder ) and connect to Ubuntu using SSH connection: 
$ ssh myusername@111.222.33.44 
(use your Ubuntu credentials here, we were using the ones in PHPStorm Deployment configuration) 
B. Log in to the root account: 
$ sudo su 
C. Run Docker: 
$ docker-compose up -d 

Step 5: Connect to the database 

1. Log into your Docker container: 
   $ docker exec -it myproject_php bash 
   $ cd /var/www/html/public/ 
   B. Download MYSQL Client: 
   $ wget https://github.com/vrana/adminer/releases/download/v4.7.7/adminer-4.7.7-mysql.php 
   C. Find database credentials (in Docker configuration files), ex: 
   DATABASE_URL=mysql://root:mypass@mysql:3306/mydatabasename 
   C. Open the following link in the browser: http://localhost/adminer-4.7.7-mysql.php 
   Server: mysql 
   Username: root 
   Password: mypass 
   Database name: mydatabasename 

Docker WordPress with 50ms response 

Docker on Windows where commands are run from the Ubuntu App has a really good response time. Instead of using emulation, the container runs natively on Linux. A single blog post page in WordPress response (TTFB) is 50ms, which is quite a good result!

This Docker solution is not only for WordPress 

This solution for fast Docker in Windows is not only restricted to WordPress CMS. There is no difference if you’re using PHP Symfony, React Node server or Ruby on Rails – you will see the difference in performance speed. 

Summary 

That’s it. We’ve configured: 
– WSL2 on Windows 
– Ubuntu Linux on Windows 
– PHPStorm Deployment 
– Running Docker from Ubuntu 
– Have ability to access Docker database 
This configuration allows Docker to run really fast. Instead of waiting 60 seconds, now the browser request will run faster than 1 second! 

Troubleshooting 

* Error after trying to start Docker, ex: ERROR: Encountered errors while bringing up the project. 
– always use Ubuntu being logged in as a root: 
$ sudo su 
* I see an error related to “not sufficient permissions” 
– Run Powershell or the SSH Client using the ‘Run as administrator’ option 
* I can’t install SSH on Win Ubuntu: 
sudo su 
apt install openssh-server 
service ssh start 
service ssh status 

If you get the following error: sshd: no hostkeys available – exiting : 
https://www.garron.me/en/linux/sshd-no-hostkeys-available-exiting.html 

If you get the following error: Permission denied (publickey): 
nano /etc/ssh/sshd_config 

Find: PasswordAuthentication 
Set it to: yes 
#and then restart the ssh service: 
service ssh restart

* hyper-v is not enabled 

To Enable Hyper-V 
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V –All 

To Disable Hyper-V 
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All 

https://www.poweronplatforms.com/enable-disable-hyper-v-windows-10-8/ 1 

* Check if hyper-v is enabled: 
Run WIN Powershell (with Admin rights) and execute: 

$hyperv = Get-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V-All -Online 
if($hyperv.State -eq “Enabled”) { 
Write-Host “Hyper-V is enabled.” 
} else { 
Write-Host “Hyper-V is disabled.” 
}

• I have tried with the latest version of my channel (Stable or Edge)
• I have submitted Diagnostics
• I have included the Diagnostics ID in this Issue
• Windows Version: Windows 10 Pro
• Docker for Windows Version: 10.03.0-ce

Expected behavior

Be able to run all the commands with relatively good response time.

Actual behavior

The response times are pretty awful. They are on at least 25x slower than the Docker Toolbox.

Information

Diagnostic ID: E8F1D8B2-B010-4076-BF6D-E78E749871E8/2018-04-10_13-17-34

Currently running Windows 10 Pro, with 32GB memory, 1TB SSD, Intel quad-core at 2.8GHz (not hyperthreading processes), so pretty good hardware.

Using Docker for Windows with Hyper-V enabled.
Equally slow on Windows and Linux Containers.

Reset to default and failed to achieve any difference.

Equally slow with cmd, powershell, and git bash terminals.

Settings for Docker increased to 10GB memory and 4 CPU cores with no improvement.

Already up to date, so updating won’t help.

Steps to reproduce the behavior

1. … Download Docker for Windows
2. … Use it and cry

Еще не опытен в докере, поэтому возможно чего то не знаю
Проблема в следующем:

Установил докер, написал небольшой docker-compose с обычным nginx и php-fpm
Все работает, с этим проблем нет
Но то КАК это работает вызывает кучу вопросов

Используется composer, если использовать «нативный» композер, то он устанавливает все зависимости за уловные секунд 40-50
Если устанавливать зависимости из под контейнера, то это спокойно можно идти заваривать чай. Все устанавливается минуты за 2 если не больше

То же самое с npm. За время которое работает npm run dev можно спокойно идти по своим делам

Так же при открытии обычной страницы
Если делать это «по старому»(не через докер) то все грузится за пару секунд
Если заходить через докер, то это не менее вечных секунд 30

Все это дело происходит на маке:
MacBook Pro (Retina, 13-inch, Late 2013)
2,6 GHz 2‑ядерный процессор Intel Core i5
8 ГБ 1600 MHz DDR3
Macintosh HD
Intel Iris 1536 МБ

Думал что может дело в системе, тк до этого не пользовался докером и была целая куча разных пакетов установлено. Решил почистить систему, но результата это не принесло
