2. 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. My goal is to use the docker-cli in Windows (docker.exe), but using Linux containers, without the installation of Docker Desktop. It is all internet connectivity: I cannot ping 1.1.1.1 but I can ping the docker host from a container. 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. The daemon is running in wsl so probably you need to specify paths in the wsl subsistem. Using apt install --reinstall iptables. My simple repo can have you up and running. Hello, there is a small error in regex provided to get the host's IP address; if the output of ifconfig eth0 returns this: it will match the line starting with "TX packets too". I have written about getting Podman to work on WSL 2. The vague complaints of the Copilot plaintiffs are nothing compared to the damage to free software and human progress if they won. 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. 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. However I agree developing linux apps with docker on windows can be a pain I'd recommend just installing linux on a dedicated machine for that purpose if you can. May I suggest 36257. Probably not necessary, but on Ubuntu/Debian: Alpine (probably not necessary, but just in case): Alpine: Nothing needed. 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 ! But since I had no success, I went on. Windows 11 Pro for Workstations: 6 TB. 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. I make games in my free time. Thanks for the help. With you every step of your journey. Docker on Windows without Docker Desktop volume mounting, https://dev.to/_nicolas_louis_/how-to-run-docker-on-windows-without-docker-desktop-hik, How Intuit democratizes AI development across teams through reusability. Step-1: Download the " Docker Desktop for Windows " exe file from here ( https://hub.docker.com/editions/community/docker-ce-desktop-windows/) and run it to install. To get to a Linux directory while in Powershell, try something like. 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. I also tried another custom docker with a fresh VANILLA minecraft install. 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. 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. lack of proper bluetooth drivers (mSBC not supported, so headset sound was crap), Teams would not switch to headset mode automatically, nor detect when BT headset was connected after app was opened), no edit and continue on .net core (and no, I won't change the language we write at work), watching 4K videos on my 4K screen had tearing (and yes, watching videos on my break is a requirement). ){3}[0-9]{1,3}" | grep -v 127.0.0.1 | awk '{ print $2 }' | cut -f2 -d:`, You should have something like 172.20.5.64, In WSL, there is no systemd or other init system. Confirm that whoami yields the correct username. Unless I missed a step above, when I got to "update-alternatives --config iptables" it's still broke on my system. Docker Desktop displays the Docker Desktop - Access Denied error if a Windows user is not part of the docker-users group. c:\bin\docker -H tcp://172.20.5.64 run --rm hello-world. You can follow the directions there in order to correct DNS, but of course eliminate any occurrence of sudo in those commands, as you do not have it yet, and you should still be root anyway. If you instead received an error containing something like "Sorry, user myusername may not run sudo" then you may need to follow the steps again, from the beginning. My goal is to use the docker-cli in Windows (docker.exe), but using Linux containers, without the installation of Docker Desktop. Thus Docker Inc. is only trying to get large companies to pay for the convenience that Docker Desktop offers when developing applications. ASP.NET Core. If you only plan on using one WSL distro, this next step isn't strictly necessary. 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. With a Dockerfile containing only: I was getting yum errors not resolving the name of the mirror server: Determining fastest mirrors If this fails due to network connectivity, see below. How to tell which packages are held back due to phased updates, Follow Up: struct sockaddr storage initialization by network format-string, Acidity of alcohols and basicity of amines. 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error". Docker Desktop is not supported on Windows Server 2019 OS host, Docker Desktop is only supported on Windows 10 host, Mac and planned for Linux Desktop ( there are kernel difference b/w Windows server host and Windows 10 desktop) I recommend the following: The first line tells WSL to cease auto-configuring the /etc/resolv.conf file. sudo dockerd -H ifconfig eth0 | grep -E "([0-9]{1,3}. PS C:\Users\clutat> wsl sh -c "sudo dockerd -H tcp://$ip" So the reason I use Windows is because that's where the driver support is. As a next step we also would like to run them simultaneously. While Docker Desktop on Windows can be run without having Administrator privileges, it does require them during installation. Here I thought it was because the iptables didn't follow the instructions. I had heard at Microsoft Ignite that Docker was super excited to partner with Microsoft to develop the Docker Engine for Windows Server. If the result is "!" /usr/sbin/iptables-apply. On Alpine, that's apk add sudo and on Fedora, dnf install sudo. Then add and update the repo information so that apt will use it in the future: Now we can install the official Docker Engine and client tools: The Docker daemon is a service that Docker requires to be running in the background. How can Docker Desktop mount Windows Volumes? WARN[2021-10-24T16:24:00.993150800+05:30] grpc: addrConn.createTransport failed to connect to {unix:///var/run/docker/containerd/containerd.sock 0 }. My concern was to continue to debug from Visual Studio 2019 and Visual Code directly in container. ){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 If you obtained your Linux distro from the Store, you can likely skip this step, as the default user is already set up. Done You may never look back. can you provide an example? Also note that a boot command in /etc/wsl.conf is only available on Windows 11. Rancher Desktop for windows is a very straightforward application. I suggest using the configuration file /etc/docker/daemon.json to set dockerd launch parameters. docker context will likely be your friend. This will set the default version to WSL 2, or fail if you are still on the first version. Only if you have docker desktop currently installed of course. 2.) If you are getting started with Windows Container development, one option is to install Docker Desktop. I believe there should be nearly a dozen links to other objects there. INFO[2021-11-06T15:39:08.506977000+05:30] Starting up I honestly haven't tried this with older versions of Debian. The issue is more easily reproduced on my system by just running ping commands inside the latest alpine image: The problem was that even though I had reverted to iptables-legacy in Debian, I still had iptables: "false" in my docker daemon.json. WARN[2021-11-06T15:39:10.292918800+05:30] You can override this by explicitly specifying '--tls=false' or '--tlsverify=false' host="tcp://169.254.255.121:2375" dpkg-query: no path found matching pattern /usr/sbin/iptables-legacy For me, using WSL isn't a choice against Linux, but a choice to use Linux everywhere. Great we have now docker in windows running with WSL2. You should see docker when you run the command groups to list group memberships." Get IP address in WSL2 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' Just double-checking: are you sure you have iptables installed? Note that the above steps involving the docker group will need to be run on any WSL distribution you currently have or install in the future, if you want to give it access to the shared Docker socket. (See my article on using Windows Terminal for a convenient way to use WSL and Powershell.). If the upgrade command succeeded, you can skip this section. 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. I have a Dockerfile that builds a Windows container with a development environment for the Nim programming language. Full-Stack Developer at Elliptic Marketing LLC. For good reason, Debian uses the more modern nftables, but this means that Docker cannot automatically tweak the Linux firewall. $ iptables --version WSL 1 was genius with running Linux on the Windows kernel, but of course lacked some of the features, such as containers. You are at the right place. If the whoami command returnes "root", then you will want to add a non-root user. 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. In PowerShell use Scoop to install the Docker static binaries: We now need to enable and start the Docker Service in Windows. The application data stays neatly within the container, instead of on the host file system. I would prefer a prettier straight-foreward solution. Never miss out on developer content you need to maintain a healthy developer career. at the end of the day, everybody still has bills to pay.. . Not the answer you're looking for? For instance, install and configure Fedora, or any other distro for which you can obtain a rootfs in tar format and then wsl --import rootfs.tar. Been waiting for years now. Is there a way to make Windows paths work in my current scenario? But I have other things to do than spend my time trying to argue with people that we should be allowed to get Linux machines on our corporate network. In a nutshell: Plenty more nuance and decisions below, of course. Maybe some tooling you use can't handle Podman, or you just want to put WSL through its paces. Windows Subsystem for Linux 2 sports an actual Linux kernel, supporting real Linux containers and Docker. Before proceeding, let's note that Docker Desktop is amazing. (Will report back with results..). Hi Pawel, thank you for your feedback. Uninstall . 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. When did this happen? Two ways to obtain this access: In other words, unless you want to utilize sudo or root access every time, add your user to the Docker group, named docker: Then close that WSL window, and launch WSL again. By default, they each may have a different ID, so a new one is in order. Now on to the Linux containers. I agree it must be something in iptables too. Plain and simple. Docker only supports Docker Desktop on Windows for those versions of Windows 10 that are still within Microsoft's servicing timeline. It requires a small proxy application to make it work though. If it returns "Yes, that ID is free" then you are good to go, with the following: Or, if groupmod is available (which it is on Fedora, Ubuntu, and Debian, but not Alpine unless you sudo apk add shadow), this is safer: Once the group id has been changed, close the terminal window and re-launch your WSL distro. 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. Windows 11 Education: 2 TB. Stefan Scherer is maintaining the project docker-cli-builder on GitHub where we can download the docker.exe command in standalone : Once done, logout from your session and log again code of conduct because it is harassing, offensive or spammy. Once suspended, _nicolas_louis_ will not be able to comment or publish posts until their suspension is removed. WindowsDockerDev Container VS CodeRemote Development Windows. It's a peaceful symbiosis. 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" And further emphasis on the optional nature of the /mnt/wsl/shared-docker socket directory. And I use WSL2 because Linux excels at CLI and daemons. Windows 11 Pro: 2 TB. What does not work is binding or mounting volumes to local directories, which used to work, when Docker Desktop was installed. In fact this is what Docker Desktop is doing, allowing all Windows native applications to use npipe docker context. Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was I set that host path in that previous tutorial in the daemon.json file. The builder is the oldest and slowest, but gets the job done. Here is what I get: $ update-alternatives --config iptables 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. In the same PowerShell session enter: Markus Lippert I was a long time unqualified hacker/gamer/tinkerer before I realized I should be doing this for money and became full-time dev. ):/usr/share/nginx/html:ro', Reading about what goes on under the hood, See more details about the Docker subscription model here, I have written about getting Podman to work on WSL 2, Microsoft's has step-by-step instructions on how to upgrade to WSL 2, utilizes iptables to implement network isolation, How to Upgrade from Fedora 32 to Fedora 33, http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container, How to Upgrade to Fedora 37 In Place on Windows Subsystem for Linux (WSL), A "POSIX Playground" Container for Shell Script Testing, Writing Bash Scripts that are not only Bash: Checking for Bashisms and testing with Dash, Instead of using an init system such as systemd to launch the Docker daemon, launch it by calling, If sharing the Docker daemon between WSL instances is desired, configure it to use a socket stored in the shared, If sharing and privileged access without sudo are desired, configure the, For simplicity, rather than launch a Windows-based Docker client, launch.

Never miss out on developer content you need to maintain a healthy developer career. Then this issue just went away, regardless of whether I ran WSL as admin. While you can create container images manually by running the docker commit command, adopting an automated image creation process has many benefits, including: Storing container images as code. See details regarding the companion Github repo by scrolling to the bottom. Working with Windows Containers without Docker Desktop from PowerShell. Under the hood, rancher is managing for you all the complexity of creating a Linux subsystem and configure it to work with docker. Here is what you can do to flag _nicolas_louis_: _nicolas_louis_ consistently posts content that violates DEV Community's Watch out for the networking bridge installed by Docker, it can conflict with other private networks using the same private IP range. HyperV is not stable enough on Linux, and VirtualBox is blocked by corporate rules. Yeah, I have actually changed the instructions, removing the iptables:false, as using iptables-legacy seems like the right way to do it. I don't have a complex use case for it but I think it works. Make sure the Docker daemon is running, then launch a new Powershell window, and try the hello-world container again. But yes, I used WSL2 enough that moved to a second PC with native Linux. I found my debian environment is configured to use iptables-nft: $> sudo update-alternatives --config iptables I know I did before, I'm not sure what I left out - but the iptables-legacy isn't set-able now. But that never worked for me for some reason. For Alpine or Fedora, use adduser myusername to create a new user. Exactly, this is very unfortunate but currently only linux has a standalone daemon, Windows and MacOS have to install Docker Desktop to get a native daemon. No one tells me these things. Those are a bit hidden and not easy to find. I had the same error, it seems it's because you are using WSL version 1. Something like this will work well if you do not already have that file, or a [user] section in it: However, if on a version of Windows before build 18980, then you will instead need to edit the registry to set a default user. 0.0.1 |awk '{ print $2 }' | cut -f2 -d: So I added some sleuthing to the Dockerfile: FROM centos:7 RUN cat /etc/resolv.conf && ping -v -c2 host.docker.internal && ping -v -c2 1.1.1.1 && ping -v google.com && ping -v mirrorlist.centos.org RUN echo "timeout=30" >> /etc/yum.conf && cat /etc/yum.conf && yum -y install httpd. From there you can simply use these paths as youve mentioned. 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". How is Docker different from a virtual machine? You could also make a batch file with the appropriate command in it. Either Windows is remembering somewhere that it doesn't add the iptables-legacy rules, or I'm missing a package (or more than one) somewhere. Another option may eventually be Rancher Desktop if they add Windows support, but it is currently limited to Linux containers. 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 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.
