Test #2 and Test #3 are equally slower on docker (~ 83%), even though one test has disk I/O and the other does not. WSL 2 shares won’t get you file changes in sync, a problem still persisting from over a year. WSL 2 is a new version of the architecture that powers the Windows Subsystem for Linux to run ELF64 Linux binaries on Windows. Thanks, I think for now I'll stick with wsl2 and run from the Linux system. SOLUTION: Run Docker Windows from Ubuntu 20.04 LTS with WSL2 enabled. Install the Docker WSL 2 Technical Preview. Based on this analysis, we worked hard to redesign Docker Desktop’s WSL2 integration in a more robust and easie… To be able to install WSL 2, you only need the "Slow" setting, meaning you will get a pretty stable preview version of Windows. I’m curious to see what the solution ends up being. I am a total noob to docker so take everything I say with a liberal dose of salt. if you use Debian, \\wls$\debian will be / in your WSL2 distribution. After that is installed, the instructions for setting up WSL 2 are very easy. We also used it ourselves a lot, and took the time to evaluate its architecture. pl Wsl2 Same laptop, same test, but running from the a directory on the Linux file system; 4.9 seconds from hitting enter on npm start to the standard new project page rendering. Check out the Comparing WSL 2 and WSL 1 on Microsoft Docs for which WSL version suits your use-case the best, since for now, Microsoft has indicated that both projects will be kept alive separately. However now the load times are slow but acceptable. We are very excited about this technology, and we are happy to announce that we are working on a new version of Docker Desktop leveraging WSL 2, with a public preview in July. The performance is incredible (on a par with native Linux installations) and the WSL2 command-line environment is fresh and clean. Moving the files over to \\wsl$\Ubuntu\home\
\ fixes the issue. This will also require a restart along the way. Unusable slowly. The Docker daemon runs well on it with great performance, and the time it takes from a cold boot to have dockerd running in WSL 2 is around 2 seconds on our developer machines. Benchmarking Performance. Gatsby.js is horrendously slow on wsl2. I mean really slowly. I … 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 … Were you volume mounting your vendor directory along with your project though? Its pretty incredible, because there's now a Linux kernel inside Windows. DEV Community – A constructive and inclusive social network for software developers. seems we have a goer. Enable WSL 2 by following this guide. Once in the program, you should be able to install the latest build from the Slow Ring. Ignore docker distributions. I’ve recorded a video of how I have Docker Desktop along with WSL 2 working together along with other tools that I use.. I’ve decided to keep this post … The way I develop is I run the VS Code extension for Remote Containers and that mounts the workspace/folder to the container, so that it's isolated from other projects. Would the container isolation work the same way if all the projects are on the Linux file system? I altered the amount of ram available and processors, checked DNS looked at network stacks, etc to no avail. Doing similar things. Much too slow for me to think about moving away from PowerShell. Because WSL2 was supposed to be faster then hyper-v I jumped through all the hoops and there was a few, to bring win10 up to that level and enabled it in docker desktop. Earlier this year, we released a technical previewof our vision for the future of Docker development on Windows using WSL 2. It's sad. Your compose file should do something like this: Where /opt/app/vendor is the location of your vendor files. You can do that using the following guide, or follow these steps: Install Windows 10 Insider Preview build 18932 or later. flowmeapp_web_flowme_1 is the container that's running nginx, as you can see it's only consuming 3.4mb of memory and there are 14.6GB available. I'm running on a Windows Insider Slow build so that I can leverage WSL 2, the Windows Subsystem for Linux v 2. This new architecture changes how these Linux binaries interact with Windows and your computer’s hardware, but still provides the same user experience as in WSL 1 (the current widely available version). We received lots of feedback from Windows Insiders via different channels, and collated common failure cases. I also installed the wonderful windows terminal app from the app store. $ sudo service docker stop $ sudo service docker start Running CUDA Containers. We strive for transparency and don't collect excess data. I am talking container starts that take 5 minutes or more and refreshing a page taking at least 30-60 seconds. If I recall correctly (and that is suspect) with WSL and Docker, it is better to put your project files inside the Linux file system. The docker service create command does not support the -v or --volume flag. How slow? Once installed, Docker will recognize that you have WSL installed and prompt to enable WSL integration. Local filesystem is blind to what docker's doing in that storage space. Update in 2020: Now that Microsoft has released the Spring 2020 Windows update we have access to WSL 2 on all editions of Windows 10 (including Home). Also under Windows and adding the folder the Windows Deference exclusions makes no difference. Having my files on the Linux FS makes absolutely no difference to the compile time. Before you install the Docker Desktop WSL 2 backend, you must complete the following steps: This works well now (performance wise) and still isolates the project from the system. This will take a while, as most Windows updates do. With you every step of your journey. You've got layers upon layers of abstraction there. i think it is really because internally its like a network mounted drive. Docker volume has no local copy to coordinate with, so you won't be able to access that instance of the project from the Windows side, but if you're just working in the container like I do it doesn't matter at all. That was interesting. We're a place where coders share, stay up-to-date and grow their careers. It turns out that WSL2 can be really fast but... only if you use the Linux file system. A short trip back to the Windows side! I wanted to rapidly spin up test/modify/debug a software stack. Templates let you quickly answer FAQs or store snippets for re-use. I find everything is quite a bit more sluggish. The two big gotchas are: WSL 2 is still not quite there when it comes to intensive tasks. I've been using the beta since it landed in Windows Insiders and I quickly switched over to … Nik Janetakis’ article explained this very well but I did not feel secure enough to run my service with this configuration. Here is how I have just solved this issue. Another bummer for … The previous way to do Docker-y things all happened through the Linux terminal. Inside of the initial release of Windows 10, version 2004, and in the latest Windows Insiders slow ring preview build you will temporarily need to manually install the Linux kernel, and will receive an update in a few months that will add automatic install and servicing capabilities. WSL1 is the choice to go for if you want to have good performance across OS file systems! Docker Desktop uses the dynamic memory allocation feature in WSL 2 to greatly improve the resource consumption. I used Docker + PHP stacks extensively in my past job and I found that mounting the vendor directory is almost always the bottleneck in dragging down performance. Then I spun up laravel. Additionally, with WSL 2, the time required to start a Docker daemon after a cold start is significantly faster. very excellent! It took a while to work it out but the problem is mounting a windows path into a container is sloooow. I tried running it like that and it seems to work much faster (all files are now on Ubuntu file system): Launch cmd, use wsl, navigate to Ubuntu file system, type "code . WSL 2 with Visual Studio Code. Open a separate WSL 2 window and start the Docker daemon again using the following commands to complete the installation. Anything wrong doing that? Even then, the WSL2 bandwidth is severely limited as it is only 20-25% of … Volume removal is a separate step. It's not slow but I've noticed things are much slower on wsl2 than on a comparible Unix machine. We made th… /mnt/c/.. is really slow as you said. Basically I allocate a docker volume (docker volume create ), mount it in my development container, clone my repository into the volume, and work entirely within the container. I RDP into this environment. When opening files stored on Windows (where all mine are/were) it painfully slow. Installing ubuntu and then issueing docker commands from inside ubuntu rather than from powershell improved the situation but not enough to make it worthwhile. 10 new Vscode Git Slow results have been found in the last 90 days, which means that every 9, a new Vscode Git Slow result is figured out. Updating `ls` output display in WSL2 and Windows Terminal, Skipping Auth0 consent prompt for local development, Getting A JWT access token from Auth0 in a React SPA. The docs on how to do this should be on the docker site but I’m on mobile so I’m having trouble finding it. Built on Forem — the open source software that powers DEV and other inclusive communities. WSL 2 will be available in Windows 10, version 2004. Auth0 Ambassador, Clean code enthusiast, code crafter, organiser of the Newcastle Coders Group, trying to speak more. This means, Docker Desktop only uses the required amount of CPU and memory resources it needs, while enabling CPU and memory-intensive tasks such as building a container to run much faster. I was having the same issue on WSL2, and I was surprised because WSL2 was advertised as faster. I tolerated this for a few days as I could not find a solution online that worked. After you have joined the insider program, go to Windows Update to install the next preview version of Windows. In this section, we will walk through some examples of running GPU containers in a WSL 2 environment. The docker volume is just a chunk of storage space allocated for docker to do whatever it wants, including maintaining its own filesystem that contains your project. I typically like to write my software in Node JS, TypeScript and React and I assumed I would be fine jumping into the projects I had previously been working on in my previous Windows and Power Shell environment. I'm using Docker for Windows with the WSL 2 backend as it works on W10 Home. Press J to jump to the feed. [Docker](http://www.docker.io) is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. When making requests to nginx container on docker on wsl2, the server takes a lot of time to answer. When mounting a volume into a service’s containers, you must use the --mount flag.. Populate a volume using a container I thought that there was something wrong with my Node and WSL set up and I started looking for Node issues on WSL2. So my setup was meant to be docker desktop on windows 10 for a rapid test and development environment. By default this will be handled entirely by Windows, just like regular updates on your machine. I'm not 100% on this but i think it's limited to 1 core. It's not slow but I've noticed things are much slower on wsl2 than on a comparible Unix machine. thus the additional delay. ", open in Docker container. however, now that it has options to browse files on explorer, i think sticking to linux FS is okay. That’s just insane! I did have a couple of issues. I've been playing around at using WSL2. Our end goal is for this change to be seamless, where your Linux kernel is kept up to date without you needing to think about it. Lukasz Kolko, 2020-01-21 Painless way to WSL 2 with Docker. What they have in common is sending the data back over the JDBC connection. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more. I had tried WSL before, but, besides the slow file system speed, the mayor dealbreaker was the inability to use Docker without exposing the daemon outside of TLS. I have no idea why this would make a difference. If you start a docker container in your (Linux) terminal, it will appear in, and can be controlled through the interface. You can use WSL2 file system itself. I created a windows 10 VM in our datacentre installed all the appropriate stuff including making sure WSL2 was on and docker desktop was using it. Nothing against docker, this usage case isn't good for it though (remember docker on windows virtualises a linux kernel in itself). WSL2 with DDEV-Local is a wonderful new world for Windows developers. Running npm start on my Lenovo Yoga laptop with an i7 processor and 16gb of RAM on a Create React App project freshly set up, It took 4:50, 4 minutes and 50 seconds to render the page when running from the Windows file system. By introducing the Windows Subsystem for Linux (WSL), Microsoft gave the opportunity for developers to run a GNU/Linux environment directly on Windows, unmodified, without the overhead of a virtual machine. With Windows 10 introducing WSL2 you can now run Docker image from Ubuntu running via WSL2 that’s connected to your Host’s Docker Desktop app. It’s inception in OS level. Here’s a guide on User Experience changes from WSL 1 to WSL 2. In this piece, we use PyBench and thePhoronix Test Suite to benchmark performance inside Docker containers.PyBench uses a mixture of built-in function calls and nested for loops to simulate a typical compute-heavy Python application.. Test #1 that simply opens and closes JDBC connections is 42% slower for Docker. Ubuntu is fast, its a wonderful development experience all my favorite linux tools. However, since WSL 2 now runs on a Linux kernel with full system call capacity, Docker can fully run in WSL 2. This gave my workflow a massive (30x) cut in compile time. If you want a fast experience using WSL2 move your projects to the Linux file system. Prerequisites. So basically I put the project files inside WSL2 now. Of particular importance for modern webdev, Docker for Windows has built-in support for WSL2 and the performance is stellar (with some caveats). New comments cannot be posted and votes cannot be cast. VSCode > WSL2 > Windows > Docker > Docker virtualized linux kernel > Ubuntu. I basically run the .devcontainer from VS Code. first I had to enable mounting in docker desktop (under settings resources, click the + icon), and an issue where the container was rebuilt from scratch and refused to start due to the pre-existance of some files in the vendor/bin folder (I was reusing the existing build). Install Ubuntu from the Microsoft store. I work on an i7 Mac for work but have a similar spec i7 dell laptop and it's quite a lot slower. All good. WSL1 is the choice to go for if you want to have good performance across OS file systems! Install the Remote - WSL extension for VS Code. WSL 2 using its built in NTFS support (going via the 9p service exposed bythe Window host) is unusably slow. WSL2 does allow you to do multiple copies of the same OS, so you'll get to the same thing. The thing I noticed was that my React projects seemed to be running slowly. Removing the service does not remove any volumes created by the service. So it's not at all slow, once the operation is running inside the database. To check the current version, just run in cmd: wsl.exe -l -v It will show: C:\Users\Ivan>wsl.exe -l -v NAME STATE VERSION * Ubuntu-18.04 Stopped 1 docker-desktop-data Running 2 docker-desktop Running 2. Docker containers transpiling js. Today, you will need to install the Windows Insider Slow ring build. Install Windows 10 Insider Preview build 18975 (Slow) or later for WSL 2. I was just shocked when I was caught out by the initial slow performance. But as usual, there are caveats. Is there anything I can do or is that just the way it's supposed to work? Now configure your WSL distribution to run WSL version 2 (I had 1 by default). They even backported in support for WSL 2 in Windows versions 1903 and 1909. This means that using WSL2 is much more of an all or nothing break than I would have liked, but I'm still thinking I'll commit to the change, at least for new projects. DEV Community © 2016 - 2021. I worked solely inside of my Windows files which were mounted into the Linux system. I put on some music and timed it. September 3, 2019 by Matt Hernandez, @fiveisprime It's been a couple of months since the initial betas for the Windows Subsystem for Linux 2 (WSL 2) were launched and I wanted to share a bit about what this is all about and how this will help you be more productive. If you have used either WSL or Docker you’ve already experienced some magic of virtualization. If you are mounting your project folder from in Windows then the files need to do a conga from Windows, then Linux then the container. Everything works but compiling JS projects is very very slow. This will prevent Docker from attempting to mount your entire Vendor directory (which is likely huge). WSL 2 is still not quite there when it comes to intensive tasks. Try using docker volumes instead of mounting your project from the local file system. As noted in the WSL2 blog article, Visual Studio Code is doing great with WSL2, but PHPStorm is lagging a bit behind.However, it is possible right now to use PHPStorm with … Important: WSL won't give you a GUI for your Linux distros. A simple request that returns a plain ##text takes up to 4 seconds. Docker Desktop. It's more like having Linux servers running on your Windows machine. In WSL version 1, due to fundamental differences between Windows and Linux, the Docker Engine couldn't run directly inside WSL, so the Docker team developed an alternative solution using Hyper-V VMs and LinuxKit. The short answer is yes, and this is slow. While this is fine, the Docker Desktop for Windows application integrates with WSL2 quite well and provides a GUI.. Syntax differences for services. Press question mark to learn the rest of the keyboard shortcuts. This is my first time using Window Subsystem for Linux having skipped over WSL1. By contrast, mounting a local directory in your container, docker needs to coordinate with the underlying filesystem, making sure any changes you make in the container are properly reflected locally; this adds significant overhead and is super slow on WSL. wsl Gotchas with WSL 2. Check out the Comparing WSL 2 and WSL 1 on Microsoft Docs for which WSL version suits your use-case the best, since for now, Microsoft has indicated that both projects will be kept alive separately. There is a ready-made Docker image, so running the benchmark is simple: $ docker run -it phoronix/pts Unable to find image … Speed when transferring between file systems is a little slow right now. Alternatively, you can select Settings from the Docker system tray icon menu, then choose the General tab, check Use the WSL 2 based engine, and hit Apply & Restart. So I rolled it all back to hyper-v. now it works reasonably. The actual limit for the WSL bandwidth is being captured by the Docker container running within WSL2, and that is almost 10x the download speed, though upload speed is fine. To run the Docker Desktop WSL 2, you will need to set up the Windows Subsystem for Linux 2 (WSL 2) first. It takes less than 10 seconds to start the Docker daemon when compared to almost a minute in the previous version of Docker Desktop. For anybody who comes here looking for the answer like I did. So how fast can it be? The following is a step-by-step guide to help you get your Node.js development environment set up using Windows Subsystem for Linux (WSL). Made with love and Ruby on Rails. That’s not a worry for me since I never transferred. I then mounted my local project folder into the env (./public_html:/app) and everything went to shit. (its on \\wls$\.... ) I can't wait for this to be out of…
