I set that host path in that previous tutorial in the daemon.json file. so before that gets out of control: I'd like to share one that I did discover just this morning: devopstales.github.io/home/docker- it has lots of helpful information presented in a clear way, and the alternatives it lists don't require any "special magic" to get working, which might be very appealing for some. Another option may eventually be Rancher Desktop if they add Windows support, but it is currently limited to Linux containers. Due to the license issues with docker desktop and the fact that you don't really need this buggy bit of software, this guide will walk you through the steps to use VSCode+remote-containers in combination with WSL2 without using docker desktop. It just isn't setting up the legacy rules. Is there a way to make Windows paths work in my current scenario? Here is the corrected version: ifconfig eth0 | grep -E "([0-9]{1,3}\. Err :connection error: desc = "transport: Error while dialing dial unix:///var/run/docker/containerd/containerd.sock: timeout". If you dont want to switch between Windows and WSL when running Windows or Linux containers, you can just expose the Docker Daemon in WSL2 and create a context for it. Setup Docker for Windows Containers (NO Docker Desktop Needed!) Thanks for keeping DEV Community safe. Not so ideal for development with that heat on my hand . DEV Community 2016 - 2023. Reading about what goes on under the hood is an entertaining and informative endeavor, as well. If the /etc/docker directory does not exist yet, create it with sudo mkdir /etc/docker/ so it can contain the config file. Well, this is a game changer. In a windows terminal (Windows Power Shell) , launch : sudo dockerd -H `ifconfig eth0 | grep -E "([0-9]{1,3}. Best possible hardware drivers by default. 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. On Fedora, you will additionally need to passwd myusername and enter the password you want to use. By default, non-privileged Windows users cannot reach the Docker Service. I reinstalled the Debian WSL. I agree it must be something in iptables too. Unless I missed a step above, when I got to "update-alternatives --config iptables" it's still broke on my system. ibb.co/yQGVZ18 On removing that, docker can use its default iptables impl and work with Debian Bullseye. Looks too much tricky for me. I would suggest trying to modifying your run command with those paths, so something like: Make sure you pay attention to the slashes: in WSL you need a foreward slash (/) whereas windows does not really care. This is because all Windows accounts use the same VM to build and run containers. Hi Pawel, thank you for your feedback. Even after upgrading WSL to 2 and running wsl --set-default-version 2, my distribution was still WSL1 as it was created before the upgrade. If you only run one it doesn't hurt, but you could use Docker's default location, /var/run/docker/containerd/containerd.sock. From there you can simply use these paths as youve mentioned. But yes, I used WSL2 enough that moved to a second PC with native Linux. Thanks for your help! Chris 192 Followers Follow More from Medium Tony DevOps in K8s K9s, Terminal Based UI to Manage Your Cluster Flavius Dinu Wsman Shell commandLine, version 0.2.1. About. Windows Subsystem for Linux 2 sports an actual Linux kernel, supporting real Linux containers and Docker. 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. Get:1 deb.debian.org/debian stretch/main amd64 iptables amd64 1.6.0+snapshot20161117-6 [288 kB] Specifically, you use the the Containers extension of your Windows Admin Center instance to run the containers. I'm curious why you'd use a custom script to start dockerd rather than just using service docker start? 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. Once unpublished, all posts by _nicolas_louis_ will become hidden and only accessible to themselves. If you want a more generalized "if this is wsl, then set the socket pro-actively" then you may prefer the following, which simply check for the existence of a /mnt/wsl directory and sets the docker socket if so: If configured as above, I recommend always running docker from wsl. For Linux containers you can install the Docker Daemon in WSL2. This article attempts to explore such a process and options along the way. I got this so I just added "iptables": false to my daemon.json and this error was averted. But that never worked for me for some reason. Watch discussions for Docker-related .NET announcements. For further actions, you may consider blocking this person and/or reporting abuse. Still same error after switching explicitly to iptables-legacy in debian 11. I did that but it did not work for me. If so, you have success. But I wanted something truly distro-agnostic. Thankfully, there are official guides for installing Docker on various Linux distributions. And sometimes its also fun to have a bit more insight on whats going on behind the scenes. I mean? 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). (If your Fedora does not have passwd, then you will need to first dnf install passwd cracklib-dicts). If the whoami command returnes "root", then you will want to add a non-root user. Here I thought it was because the iptables didn't follow the instructions. I think spending some money for that is perfectly fine regarding the value Docker Desktop is providing to you. Hey Derek, I believe the \mnt\wsl location is chosen so multiple Linux installations can share the same docker daemon. If using the script earlier to launch dockerd, then $DOCKER_HOST will be set, and future invocations of docker will not need an unwieldy -H unix:///mnt/wsl/shared-docker/docker.sock. With you every step of your journey. I was a long time unqualified hacker/gamer/tinkerer before I realized I should be doing this for money and became full-time dev. Use this image for your development process (developing, building and testing applications). I recommend the following: The first line tells WSL to cease auto-configuring the /etc/resolv.conf file. Weird -- containerd is already installed on mine; I can update the instructions accordingly. It's easy, by default (at least for me) wsl has mounted all drives in /mnt// for example /mnt/c/ for C: Drive and /mnt/d/ for D: drive ", echo `ifconfig eth0 | grep -E "([0-9]{1,3}. Once suspended, bowmanjd will not be able to comment or publish posts until their suspension is removed. Then in the elevated PowerShell install dockeraccesshelper with: Import the dockeraccesshelper module with: Note, if you encounter the following error: Run the following to enable execution of remote signed PowerShell scripts for the current user: Finally, we need to configure dockeraccesshelper by running: Substituting DOMAIN and USERNAME for the domain and username of your non-privileged user. So we need to launch manually docker with the automatic collect of the IP address, sudo dockerd -H `ifconfig eth0 | grep -E "([0-9]{1,3}. (Just dial DOCKR on your telephone keypad) Not likely to be already in use, but check anyway: If the above command returns a line from /etc/group (that does not include docker), then pick another number and try again. Creating A Lightweight Windows Container Dev Environment without Docker How to containerize windows desktop applications (with GUI) using docker? Why do we place the docker socket in the \mnt\wsl folder? Before you can install Docker you need to enable systemd. Made with love and Ruby on Rails. Redefined, https://download.docker.com/linux/${ID}/gpg, Ubuntu on WSL2 : in Microsoft Store Ubuntu 20.04 LTS, Docker extension for VSCode : directly from Visual Code Extensions Marketplace. 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. I had heard at Microsoft Ignite that Docker was super excited to partner with Microsoft to develop the Docker Engine for Windows Server. More information about the setup, my NAS and Disks are less then a year old and in perfect condition. Thanks for this post, very useful previously. sudo nano /etc/resolv.conf I will definitely try that, and update the article. 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. Podman is daemonless (no background service needed), modern (cgroups v2 out of the box), supports rootless, and serves as a drop-in replacement for Docker. It will become hidden in your post, but will still be visible via the comment's permalink. OS Build 19044.1586". 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. Restart WSL engine (restart Lxssmanager service on Windows host), Run WSL prompt as Admin (elevated) and there only run. One mistake and you can cause irreparable damage to your Windows installation. Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? Now I have started using docker desktop again. failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables v1.8.4 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Have you managed to mount volumes from windows to docker image running in WSL2 ? with all that said: I do sincerely hope that anyone able and/or required to pay for a license actually does so it would be really sad for Docker to have come this far, having influenced so many aspects of "containerization", only to fade into the background because of "suddenly not being free to everybody". Done What does not work is binding or mounting volumes to local directories, which used to work, when Docker Desktop was installed. Dev Container I even removed and installed fresh wsl. FWIW, I'm also passing the following dns servers to my containers via docker daemon.json: I've tried putting the google and cloudflare dns first in this order, to no avail. In all of the above, the principle is the same: you are launching Linux executables, using WSL interoperability. Install Docker without HyperV/VirtualBox/VMware support on Windows WARN[2021-11-06T15:39:08.509628200+05:30] Binding to an IP address, even on localhost, can also give access to scripts run in a browser. In PowerShell start an elevated shell with: Enable the elevated PowerShell to make changes in the prompt. Make sure the Docker daemon is running, then launch a new Powershell window, and try the hello-world container again. If you obtained your Linux distro from the Store, you can likely skip this step, as the default user is already set up. Watch out for the networking bridge installed by Docker, it can conflict with other private networks using the same private IP range. On Alpine, this should prompt for the new password. Is it all internet connectivity, or just DNS? I've been reading both this and "Install Docker on Windows (WSL) without Docker Desktop". How do I get into a Docker container's shell? My running container has the following DNS Servers configured: 172.27.64.1 and 192.168..1. Startup is intentionally being slowed down to show this message host="tcp://169.254.255.121:2375" Again, try wsl -l -q to see a list of your WSL distributions if you are unsure which one to use. On the official Data Gateway documentation it says th. If you open Services, you should now see the Docker Engine listed: It will start automatically on Windows boot. If, however, when you launch WSL, you are still root, then set your new user as the default. For Windows Home - Enable Windows Subsystem for Linux (Instructions Here: https://docs.microsoft.com/en-us/windows/wsl/install-win10 ). For instance, VSCode supports docker in WSL 2. The top 50 must-have CLI tools, including some scripts to help you automate the installation and updating of these tools on various systems/distros. Now, how to run dockerd and docker without copy&paste IP address in command line nor VSCode. If you dislike the Windows Store, there are other options. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. I suggest using the configuration file /etc/docker/daemon.json to set dockerd launch parameters. - It uses the same technology as Remote Desktop (think VNC), except it only does it for a single Window (and it's child windows). When did this happen? For some reason I can't get internet connection inside the container. Under the hood, rancher is managing for you all the complexity of creating a Linux subsystem and configure it to work with docker. Interesting; I just did this successfully last weekend. 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. Big Thanks to Jonathan Bowman for his article. Hi, followed everything but on doing sudo dockered getting this error. And, yes, VSCode can work with podman. iptables v1.6.0, I think iptables installs when Debian itself is installed. WARN[2021-11-06T15:39:10.291048100+05:30] Binding to an IP address without --tlsverify is deprecated. Essentially i run docker, vs code , gpu compute (inside containers too) all on ubuntu wsl2. First, let's pick one. I love POSIX as well, but I don't have a choice. 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error". You should see docker when you run the command groups to list group memberships. This doesn't just apply to the terminal, either. If so, you have success. anyways, with the deadline for this looming ever closer, I suspect there are going to be a sudden stupendous influx of "Docker alternative" and "Docker without Docker Desktop" articles, debates, and so on.. not unlike this one.
