Strange my Debian is so far behind. I was a long time unqualified hacker/gamer/tinkerer before I realized I should be doing this for money and became full-time dev. EDIT: It turned out that the eventual root cause of my issue was that my distribution was still on WSL1. This will set the default version to WSL 2, or fail if you are still on the first version. Templates let you quickly answer FAQs or store snippets for re-use. Because I do a lot from the command line, and I often want that command line to be Linux, no matter the location or network connectivity. At the moment I am stuck at step Launch dockerd and I get this error (image below). docker context will likely be your friend. The only option that we had is to run a corporate-managed VM on Azure, with their own "linux" which is a special build from oracle that I never heared of before they mentionned it, and where no open source tools seems to offer any kind of support. Before we mosey along, though: are you aware of Podman? Are you sure you want to hide this comment?

If you want Docker to work on Windows and WSL 2, installing Docker Desktop is most likely the way to go. Here is the corrected version: ifconfig eth0 | grep -E "([0-9]{1,3}\. Since Docker announced a new subscription for Docker Desktop for personal use, educational institutions, non-commercial open-source projects and small businesses, other enterprises need to acquire licences for all installations of Docker Desktop. Reading about what goes on under the hood is an entertaining and informative endeavor, as well. We are doing magic with Windows 10, Ubuntu on WSL2, docker builder cli for windows and a little elbow grease. They can still re-publish the post if they are not suspended. Lastly, if you are working behind a proxy and need access to a private container registry, and get an x.509 certificate error with docker login, grab the root certificate of the proxy from your browser (export as base-64) and drop it into the docker certs directory related to your private registry/etc/docker/certs.d/{private_reg_name}:{private_reg_port}/ca.crt (private_reg_port is optional if you're using a standard port). Docker Desktop is an application for MacOS, Linux, and Windows machines for the building and sharing of containerized applications and microservices. Debian 9, I see. Create a file called startDocker.ps1 at your location of choice and save the following script inside it: start-service -Name com.docker.service start C:\'Program Files'\Docker\Docker\'Docker Desktop.exe' Its surprisingly easy! On installation the user gets a UAC prompt which allows a privileged helper service to be installed. If you don't want to rely on a particular WSL shell script, you could implement a Powershell function to launch dockerd, such as this: This function takes one parameter: the distro name. Unless I missed a step above, when I got to "update-alternatives --config iptables" it's still broke on my system. Without needing to worry about sockets and ports, a lot of headaches go away. In PowerShell start an elevated shell with: Enable the elevated PowerShell to make changes in the prompt. ){3}[0-9]{1,3}" | grep -v 127.0.0.1 | awk '{ print $2 }' | cut -f2 -d:" And I can't see my eth0 configs in ifconfig command Why does Mister Mxyzptlk need to have a weakness in the comics? How can Docker Desktop mount Windows Volumes? On your windows, you need to install a couple of things : (Inspired from the Jonathan Bowman's article), Check if sudo is installed if not : *apt install sudo*`, You would see something like sudo: x:27:myusername, Otherwise, We use usermod to add an user to the sudoer group. If desired, you can configure it using Services to only start it manually. In VSCode, I update my Docker:Host setting with tcp://localhost:2375 : Now I can know create a dedicated powershell script with the previous line : start_docker.ps1. from a Windows terminal, my environment contains DOCKER_HOST=tcp://127.0.0.1:2375. Run Docker in WSL (Windows 10/11) without Docker Desktop | by Sung Kim | Geek Culture | Medium 500 Apologies, but something went wrong on our end. For this please install the Windows Store Version of WSL and afterwards enable systemd in the distro settings and reboot the WSL distro.. Now re-enter WSL to have systemd available and install Docker normally like explained in the docs. So is there an alternative on Windows to continue to legally use containers with a docker command and a nice UI like VSCode without paying a licence : the answer is YES ! Need to get 288 kB of archives. Before you can install Docker you need to enable systemd. I'm flummoxed. At this point if you run docker run hello-world:nanoserver as a non-privileged user, you will encounter the following error: One, to always use an elevated PowerShell to work with Docker. In PowerShell use Scoop to install the Docker static binaries: We now need to enable and start the Docker Service in Windows. From there you can simply use these paths as youve mentioned. In a nutshell: Plenty more nuance and decisions below, of course. I've been reading both this and "Install Docker on Windows (WSL) without Docker Desktop". My goal is to use the docker-cli in Windows (docker.exe), but using Linux containers, without the installation of Docker Desktop. big relief for me right there.. while this post does contain lots of super technical points (yeah, I saw those comments), this is a super technical topic.. which leads straight back to the "how" and "why" of Docker's decision on this matter. Here's the complete list: Windows 11 Home: 128 GB. You can even configure this in Windows Terminal: Second, my recommended method, is to use dockeraccesshelper to enable and configure access to the Docker Service for non-privileged users. For instance, name it docker.bat and place in C:\Windows\system32 or other location included in %PATH%. (If your Fedora does not have passwd, then you will need to first dnf install passwd cracklib-dicts). What!??? I will work on updating the instructions for systemd, then! See more details about the Docker subscription model here. Thanks for keeping DEV Community safe. I honestly haven't tried this with older versions of Debian. Sometimes you need this simple as that. If you do not yet have a running WSL instance with a distro of your choice, the next step is to pick one from the Microsoft Store. update-alternatives: error: no alternatives for iptables. I had the same error, it seems it's because you are using WSL version 1. You have to remove the daemon.json if you want to use args command line. WARN[2021-11-06T15:39:10.294801200+05:30] Support for listening on TCP without authentication or explicit intent to run without authentication will be removed in the next release host="tcp://169.254.255.121:2375" In particular you should specify paths in WSL, usually your C:/ drive is mounted in WSL under \mnt\c. If you want Docker to work on Windows and WSL 2, installing Docker Desktop is most likely the way to go. Dockerd does work. I didn't notice the 9. (Just dial DOCKR on your telephone keypad) Not likely to be already in use, but check anyway: If the above command returns a line from /etc/group (that does not include docker), then pick another number and try again. Again, try wsl -l -q to see a list of your WSL distributions if you are unsure which one to use. After this operation, 0 B of additional disk space will be used. Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? I've played around with setting DNS in the container explicitly using the /etc/docker/daemon.json with things like "dns": ["1.1.1.1", "8.8.8.8"], but if the container can't even get connectivity to these ips that's not going to work.. My Debian environment does not have any iptables configured. Chris 192 Followers Follow More from Medium Tony DevOps in K8s K9s, Terminal Based UI to Manage Your Cluster Flavius Dinu Another option may eventually be Rancher Desktop if they add Windows support, but it is currently limited to Linux containers. I will definitely try that, and update the article. For instance, VSCode supports docker in WSL 2. If the result is a random hash string, then you are good. Most upvoted and relevant comments will be first. Unfortunately if you want to run docker from WSL (not using Docker Desktop) this will be the only way to use volumes. A hint: ever tried scoop.sh? Rancher Desktop for windows is a very straightforward application. Reconnecting module=grpc Redefined, https://download.docker.com/linux/${ID}/gpg, Ubuntu on WSL2 : in Microsoft Store Ubuntu 20.04 LTS, Docker extension for VSCode : directly from Visual Code Extensions Marketplace. Confirm that whoami yields the correct username. Get rid of docker desktop. at the end of the day, everybody still has bills to pay.. . If not, you can obtain the user id with id -u myusername and check your list of WSL distros with (in Powershell) wsl -l. Then, use the following command in Powershell, but use your WSL distro name in place of "Alpine" and use your user id in place of "1000": Whichever method you use, test by logging out of WSL, and then log back in. I only have one entry if I look for iptables: $ ls /usr/sbin/iptable* More information about the setup, my NAS and Disks are less then a year old and in perfect condition. This guide includes instructions for launching dockerd in Debian, Ubuntu, Alpine, and Fedora. For Alpine or Fedora, use adduser myusername to create a new user. I only just finished the install so I can't confirm that everything works 100% out of the box, but after rebooting the VM, dockerd was running as expected. I'll never understand why developers who write code to run in linux fight with windows. I was able to run simple commands on Windows with docker like, docker run -it --rm ubuntu sh However, I could not find an option to switch it to run Windows container. It works now. How do I align things in the following tabular environment? To work around this, you can, if you choose, tell sudo to grant passwordless access to dockerd, as long as the user is a member of the docker group. Installing Docker can be heavy-weight and add more than expected to your system. Most upvoted and relevant comments will be first, I like Innovation, technical challenges and to participate to projects like https://www.yslbeauty.com/rouge-sur-mesure (Innovations at CES, Time and Forbes : ), Head of a team liking technology challenges @ Alizent (Group Air Liquide). For some reason I can't get internet connection inside the container. Ip stuff port forwarding etc. WSL TERMINAL : docker-compose -f docker-compose.yml -f docker-compose.listener.yml up -d --build && docker attach listener Then, let's start an application on the host to handle HTTP message : WARN[2021-11-06T15:39:10.291048100+05:30] Binding to an IP address without --tlsverify is deprecated. Does dockerd work? dpkg-query: no path found matching pattern /usr/sbin/iptables-legacy, iptables is installed: For communication over the socket, privileged access is required. If you only run one it doesn't hurt, but you could use Docker's default location, /var/run/docker/containerd/containerd.sock. To get started, in Windows Features enable: Alternatively, you can open PowerShell as Administrator and run: Open PowerShell as your normal user, ideally in the new Windows Terminal, and run: If you get an error about PowerShell script execution policy: You need to change the execution policy with: In PowerShell use Scoop to install tools that improve the use of Scoop, specifically git and aria2. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Below one works fine in ubantu However, if you would like to have the option of sharing the Docker socket system-wide, across WSL distributions, then all will need to share a common group ID for the group docker. Docker Desktop gives you access to both Windows Containers and Linux containers, by leveraging WSL 2. In a windows terminal (Windows Power Shell) , launch : sudo dockerd -H `ifconfig eth0 | grep -E "([0-9]{1,3}. For Linux containers you can install the Docker Daemon in WSL2. , Practice yoga, write code, enjoy life, repeat. As with the last step, if you only plan on using one WSL distro, this next step isn't strictly necessary. I run this stack using this. How is Docker different from a virtual machine? I'm very interested if you have a simpler way to proceed :). How to copy Docker images from one host to another without using a repository. Your docker daemon is running in WSL and you are just connecting to it with de docker command on Windows. With Docker Desktop's WSL 2 backend, Docker integrates with Windows in a fairly elegant way, and the docker client can be launched from either Powershell or Linux. A Python enthusiast. Another option may eventually be Rancher Desktop if they add Windows support, but it is currently limited to Linux containers. In a windows terminal running with administrator privileges, I set the Execution policy with : And every time I want to run dockerd, I launch the start_docker.ps1 script: And if you see API Listen on 172.18.75.23:2375, Now, I want to use docker without -H parameter, for this, I add a new system environment variable called DOCKER_HOST set to tcp://localhost:2375. Now on to the Linux containers. Restart WSL engine (restart Lxssmanager service on Windows host), Run WSL prompt as Admin (elevated) and there only run. If the /etc/docker directory does not exist yet, create it with sudo mkdir /etc/docker/ so it can contain the config file. If you only plan on using one WSL distro, this next step isn't strictly necessary. If not, first make sure that sudo is installed. (See my article on using Windows Terminal for a convenient way to use WSL and Powershell.). The steps to create and run containers on Windows Server using Docker can be summarized as follows: 1. On removing that, docker can use its default iptables impl and work with Debian Bullseye. Brilliant article - thanks for the thorough write up @bowmanjd! Call me stupid, but I think, this was one of my many attempts to get this working. I got this error when I tried to run "sudo dockerd -H ifconfig eth0 | grep -E "([0-9]{1,3}. Hello, thank you for this article. Then in the elevated PowerShell install dockeraccesshelper with: Import the dockeraccesshelper module with: Note, if you encounter the following error: Run the following to enable execution of remote signed PowerShell scripts for the current user: Finally, we need to configure dockeraccesshelper by running: Substituting DOMAIN and USERNAME for the domain and username of your non-privileged user. I do wish it'd change some day. then that user has no password set. I got this so I just added "iptables": false to my daemon.json and this error was averted. If the whoami command returnes "root", then you will want to add a non-root user. WARN[2021-11-06T15:39:10.292307700+05:30] Please consider generating tls certificates with client validation to prevent exposing unauthenticated root access to your network host="tcp://169.254.255.121:2375" WSL 1 was genius with running Linux on the Windows kernel, but of course lacked some of the features, such as containers. Since I could resolve the name of the server from Debian WSL2 with no issue, I knew my DNS was working there. Other editions have even higher limits. Do so from a WSL window. I make games in my free time. On later versions of Alpine from the Microsoft Store, while a non-root user is created as part of setup, this user is initially password-less. I even uninstalled and installed it back. Be safe out there! For that you need to execute the following PowerShell commands as admin: Docker then greets you with Hello from Docker!. Would you be interested in how to do same without so much trickery? My simple repo can have you up and running. Still had no "update-alternatives" for iptables which I believe is part of the problem I was having with Docker trying to run the "Computer Language Drag Racing" suite. After setting it up, scoop install docker docker-compose will get you some familiar tools, then an SSH server such as Dropbear or OpenSSH on the WSL side A simplified method I recommend: a Powershell function that calls the WSL docker, passing along any arguments. We're a place where coders share, stay up-to-date and grow their careers. I'm curious why you'd use a custom script to start dockerd rather than just using service docker start? Here are the problems I had on Ubuntu (note that I really wanted to work on linux since our servers run on linux) : I will readily admit being a Linux newbie despite I installed Slackware with Linux 0.99pl15 for the first time from a stack of floppies early 1994. Finally, in a windows terminal, I can simply run a command like this: This article shows how we can use docker in windows and WSL2 without Docker Workstation Have you managed to mount volumes from windows to docker image running in WSL2 ? sudo: dockerd: command not found, I followed all the steps but unable to run docker on my WSL2 -, sudo dockerd -H ifconfig eth0 | grep -E "([0-9]{1,3}. Rather than twist things to use the existing init system, we just launch dockerd directly: There should be several lines of info, warnings related to cgroup blkio, and the like, with something like API listen on /mnt/wsl/shared-docker/docker.sock at the end. Find centralized, trusted content and collaborate around the technologies you use most. It just doesn't set the default links in the install process to be able to switch to the legacy rules. See details regarding the companion Github repo by scrolling to the bottom. host="tcp://169.254.255.121:2375" Sometimes, one just needs Docker to work. $ iptables --version ){3}[0-9]{1,3}" | grep -v 127.0.0.1 | awk '{ print $2 }' | cut -f2 -d: The error is: failed to start daemon: pid file found, ensure docker is not running or delete /var/run/docker.pid Thanks! When signed in as the user you set up (try su myusername if you are still root), can you sudo -v without an error? This means that every docker command is actually executed on the WSL subsystem and paths should be specified accordingly. I am a bit confused on how to solve this because Im very new to this, so I would appreciate any help. Debian and Ubuntu will configure this automatically at first launch, as should Alpine if you installed it from the Store. If your username is missing from the group, take note of the group name (sudo or wheel) and add the user in question to that group: Finally, as root, make sure that the admin group (whether sudo or wheel) is enabled for sudo: If the line is there, but commented out with a #, then run visudo then make sure the line reads thus (use wheel or sudo as determined earlier): Once these steps are complete, test again with: If you are prompted for the password, then all is well. I mainly followed these instructions to install Ubuntu 20.04-LTS using WSL2 and prepare everything that dockerd is running inside this instance. There should be several lines of info, warnings related to tls, and the like, with something like API listen on 172.20.5.64:2375 at the end. DEV Community A constructive and inclusive social network for software developers. sudo dockerd -H ifconfig eth0 | grep -E "([0-9]{1,3}. Such methods will be explored in a later article, but I encourage you, reader, to explore. Use this image for your development process (developing, building and testing applications). For further actions, you may consider blocking this person and/or reporting abuse. Trying to get started By default, they each may have a different ID, so a new one is in order. It was a miserable experience. With you every step of your journey. (Depending on your network configuration, you may instead need to access this through http://[WSL IP Address]:8080 which should be obtainable with ifconfig or ip addr). Looking forward to learning DevOps, though. Maybe the project I'm trying to compile doesn't like Debian 9! sudo apt update, sudo apt install docker-ce docker-ce-cli containerd.io, "Then close that WSL window, and launch WSL again. I'm using it on windows and I've understand the concept (a container is just a linux process with a bit more isolation than a classic process). Kubernetes can be installed and configured many ways and Dcoker DEsktop will give you one version. Thanks for the help. Containers and images created with Docker Desktop are shared between all user accounts on machines where it is installed. Also note that a boot command in /etc/wsl.conf is only available on Windows 11. If using the script earlier to launch dockerd, then $DOCKER_HOST will be set, and future invocations of docker will not need an unwieldy -H unix:///mnt/wsl/shared-docker/docker.sock. Again, this step can be skipped if you opt against using a shared directory for the docker socket. If you obtained your Linux distro from the Store, you can likely skip this step, as the default user is already set up. Only if you have docker desktop currently installed of course. You just install it as any other applications for Windows, selecting dockerd as container runtime. Yeah, I have actually changed the instructions, removing the iptables:false, as using iptables-legacy seems like the right way to do it. VS Code VS Code Remote Development; Docker Desktop for Windows; WSL2 Feel free to try it out. Thanks so much for this @jonathan Bowman, was really helpful, don't forget to do another article on installing docker-compose on a WSL Distro without passing through Docker Desktop, might be minimal but it would be a decent supplement to this awesome article of yours. The vague complaints of the Copilot plaintiffs are nothing compared to the damage to free software and human progress if they won. Install official Docker release sudo apt install docker-ce docker-ce-cli containerd.io Add user to docker group sudo usermod -aG docker $USER "Then close that WSL window, and launch WSL again. WindowsDockerDev Container VS CodeRemote Development Windows. Docker - with buildkit I would prefer a prettier straight-foreward solution. Templates let you quickly answer FAQs or store snippets for re-use. Everything will work fine when I'll see the message "API listen on 172.18.75.23:2375". In WSL2, it's not possible to assign IP address but, I can use the windows port forwarding to redirect a local port from the host to a specific one of my distribution. A couple of updates when running in Windows 11H2 (and Ubuntu 22.04 in my case): 1) systemd is now native in Windows 11H2, BUT needs an updated WSL2 install (I was using WSL v0.63 and I believe native systemd support is in v0.68 onwards) - otherwise you get, Upgrading WSL to latest version means that updating /etc/wsl.conf with. error:failed to load listeners: listen tcp 169.254.218.38:2375: bind: cannot assign requested address I don't care whether it's the fault of F5 or the community for not working -- if I can't VPN in, I can't work. Finally you can check with this command : If you see a # at the first position, the line is commented, run sudo visudo, find the corresponding line and remove the #, save and check again. Web Developer at Nortech International (pty) Ltd. What's the biggest mistake you've ever made while coding? Built on Forem the open source software that powers DEV and other inclusive communities. Docker Desktop does a lot of plumbing in the background for you but running it by yourself isnt hard either. However, you may have other settings you wish to put in daemon.json, so you may appreciate some familiarity with this topic. Then the following, when placed in /etc/docker/daemon.json, will set the docker host to the shared socket: Most Linux distributions use systemd or other init system, but WSL has its own init system. If you open Services, you should now see the Docker Engine listed: It will start automatically on Windows boot. This requires a PowerShell instance with elevated privileges as Administrator. If bowmanjd is not suspended, they can still re-publish their posts from their dashboard. Once unpublished, all posts by _nicolas_louis_ will become hidden and only accessible to themselves. Been waiting for years now. Specifically, you use the the Containers extension of your Windows Admin Center instance to run the containers. I realize that your post indicated to use iptables: false as a way to get debian wsl2 instances to work with docker. HyperV is not stable enough on Linux, and VirtualBox is blocked by corporate rules. $ dpkg -S /usr/sbin/iptables-legacy I have a Dockerfile that builds a Windows container with a development environment for the Nim programming language. Do you have iptables installed? For example trying to run jboss/keycloak mounting /opt/jboss/keycloak/standalone/data to some local path gives me: which - again - used to work with Docker Desktop, so I do not assume an error in my call. I suspect that most, however, will want to switch to iptables legacy. Not the answer you're looking for? If you are getting started with Windows Container development, one option is to install Docker Desktop. However, if you would like to have the option of sharing the Docker socket system-wide, across WSL distributions, then a shared directory accessible to all is needed. It could be embedded in a script, I suppose, and launched from other distros or Powershell. It can be any group ID that is not in use. Once unsuspended, _nicolas_louis_ will be able to comment and publish posts again. Choose a number greater than 1000 and less than 65534. One for WSL and one for "Hyper-v and windows containers" which isn't clear if that is only for windows containers, but it reads sort of like it can do Linux as well. I found my debian environment is configured to use iptables-nft: $> sudo update-alternatives --config iptables You can use Docker for Desktop, but if you don't want to pay for a license, . If you use Docker Desktop the daemon is actually running in Windows this is why it was working before. For example, Windows 11 Home can use up to 128 GB (gigabytes) of RAM, while Windows 11 Pro supports a maximum of 2 TB ( terabytes) of RAM. Currently interested in TypeScript, Vue, Kotlin and Python. Under the hood, rancher is managing for you all the complexity of creating a Linux subsystem and configure it to work with docker. I will comment with more detail in your answer. Well, let's check. Exactly my thoughts, there's too much complexity here + there's more comprehensive guide on how to install docker in Linux on official docker website which takes half of this article. You could also make a batch file with the appropriate command in it. I do have one question though. From inside of a Docker container, how do I connect to the localhost of the machine? Wsman Shell commandLine, version 0.2.1. Chances are, you already know these. Setting up Docker for Windows Containers manually is not really that hard to do. But if you prefer a lighter, command line approach to working with Windows Containers, it is possible to install and use Docker static binaries without Docker Desktop. Step-2: Enable Docker Running Environment 1.
