I'm pretty sure using the nftable subsystem is eventually what is making things not work - if I could get iptables-legacy it might be different. My running container has the following DNS Servers configured: 172.27.64.1 and 192.168..1. The flip side though is that if you are the type that prefers minimal command line interfaces then you can also install 'native' Linux Docker on WSL 2 without Docker Desktop and switch back and forth as needed. Containers and images created with Docker Desktop are shared between all user accounts on machines where it is installed. But if you, like me, feel that all the added complexity of Docker Desktop is unnecessary, you don't need Windows containers, or you are simply tired of that whale in the system tray taking so long then perhaps you want to run the docker daemon (dockerd) in the WSL distro of your choice and be happy. I did. I didn't notice the 9. $ iptables --version Once suspended, _nicolas_louis_ will not be able to comment or publish posts until their suspension is removed. The Docker static binaries are distributed under the Apache 2 license and do not require a Docker Desktop subscription, even for commercial use. If the result is a random hash string, then you are good. However, you may have other settings you wish to put in daemon.json, so you may appreciate some familiarity with this topic. If you only plan on using one WSL distro, this next step isn't strictly necessary. I am stuck here trying to start dockerd from the Windows PowerShell (in admin mode): The vague complaints of the Copilot plaintiffs are nothing compared to the damage to free software and human progress if they won. (If your Fedora does not have passwd, then you will need to first dnf install passwd cracklib-dicts). Then, select the Images tab inside the Container extension under Container Host. How to copy files from host to Docker container? In the original post it says you only need to do this for Debian but not Ubuntu, and I'm using Ubuntu so I skipped that step originally. Same results more or less. A little more suggestion about TCP access, as well. What does not work is binding or mounting volumes to local directories, which used to work, when Docker Desktop was installed. sudo nano /etc/resolv.conf I got this error when I tried to run "sudo dockerd -H ifconfig eth0 | grep -E "([0-9]{1,3}. Those licensing changes however only apply to Docker Desktop. This is a very useful tool, to say the least. On installation the user gets a UAC prompt which allows a privileged helper service to be installed. Hi, I have exactly the same issue @bowmanjd can you share any hint about how to get Internet connection working on docker containers running on WSL2? The following often works, but is not advisable when launching WSL docker from Windows: Instead of doing the above haphazardly, when launching WSL docker from Powershell, two recommendations: Then point your browser to http://localhost:8080, and happiness will result. Note that DOCKER_DISTRO should be set to the distro you want to have running dockerd. The docker desktop documentation page isn't clear to me if it will work with or without WSL (or wsl2). I have written about getting Podman to work on WSL 2. If your admin account is different to your user account, add the docker-users group. 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. Those are a bit hidden and not easy to find. 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. [sudo] password for jai: 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. Get rid of docker desktop. We tried. Assuming you have Windows build 18980 or later: simply add a user section to /etc/wsl.conf. My concern was to continue to debug from Visual Studio 2019 and Visual Code directly in container. If this fails due to network connectivity, see below. Again, this step can be skipped if you opt against using a shared directory for the docker socket. then that user has no password set. Fight? (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. I ran Linux dual boot from 2000-2004 and then as a daily driver 2004-2017. I'm having same issue, using Debian 11 on WSL2. I did "sudo apt-get install iptables" to be sure. Built on Forem the open source software that powers DEV and other inclusive communities. Maybe the project I'm trying to compile doesn't like Debian 9! 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. But in the end, turned out it was required. 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. When executing these lines you'll be prompted to enter your distro password (sudo) and I'll see after the log of dockerd. That sounds odd. Installing WSL is explained here or you can use an already existing Ubuntu distribution. For me launching dockerd failed since chain of commands with ifconfig returned some extra garbage. 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" For anyone struggling with using this behind a proxy, I found the only configuration file that dockerd looks at is /etc/environment, so set the likes of HTTP_PROXY, HTTPS_PROXY, and NO_PROXY in there before starting Docker. This doesn't just apply to the terminal, either. I realize that your post indicated to use iptables: false as a way to get debian wsl2 instances to work with docker. 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. ){3}[0-9]{1,3}" | grep -v 127.0.0.1 | awk '{ print $2 }' | cut -f2 -d: I am trying to follow the above steps on Alpine and i am not able to figure out the equivalent for launching dockerd to get the ip address. A couple of updates when running in Windows 11H2 (and Ubuntu 22.04 in my case): 1) systemd is now native in Windows 11H2, BUT needs an updated WSL2 install (I was using WSL v0.63 and I believe native systemd support is in v0.68 onwards) - otherwise you get, Upgrading WSL to latest version means that updating /etc/wsl.conf with. Do so from a WSL window. This function can be placed in your Powershell profile, usually located at ~\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1. The install documentation has two sections. Just open a new Ubuntu window and start playing with Docker!. In PowerShell use Scoop to install the Docker static binaries: We now need to enable and start the Docker Service in Windows. Either Windows is remembering somewhere that it doesn't add the iptables-legacy rules, or I'm missing a package (or more than one) somewhere. I work on client/server software. For Linux containers you can install the Docker Daemon in WSL2. It might be worth mentioning that as of a few months ago, the default WSL2 install (Ubuntu) can be configured to support systemd with a two-line config file. In the same PowerShell session enter: host="tcp://169.254.255.121:2375" Only if you have docker desktop currently installed of course. DEV Community A constructive and inclusive social network for software developers. However, due to both WSL and Docker complexities, a little tender loving care is required to get Docker up and running. You simply package each application into a container and run it. PS C:\Users\clutat> wsl sh -c "sudo dockerd -H tcp://$ip" If the above script is placed in .bashrc (most Linux distros) or .profile (distros like Alpine that have Ash/Dash as the default shell), or other shell init script, then it has an unfortunate side effect: you will likely be prompted for a password most every time a new terminal window is launched. It just isn't setting up the legacy rules. at the end of the day, everybody still has bills to pay.. . Does dockerd work? Have you heard of portainer? 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. At the moment I am stuck at step Launch dockerd and I get this error (image below). And further emphasis on the optional nature of the /mnt/wsl/shared-docker socket directory. Docker - with buildkit Hi, yes, you are right but. With docker, it is possible to mount a host system's directory or files in the container. Probably not necessary, but on Ubuntu/Debian: Alpine (probably not necessary, but just in case): Alpine: Nothing needed. xref: docs.microsoft.com/en-us/windows/w Great point. Even with that, I will still run WSL on any Windows machine I can. (Will report back with results..). Is it possible to create a concave light? ", echo `ifconfig eth0 | grep -E "([0-9]{1,3}. Updated on Apr 10, 2022. I am still running Linux on servers to this day. For communication over the socket, privileged access is required. Unflagging _nicolas_louis_ will restore default visibility to their posts. I'll never understand why developers who write code to run in linux fight with windows. Why do academics stay as adjuncts for years rather than move around? But please - why did Windows paths work with Docker Desktop before? Even pull command comes up with error 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}. If you are using it for work, and your company exceeds a certain size or revenue, then consider paying for a subscription. Now, my containers can access "the internet". The application data stays neatly within the container, instead of on the host file system. Get the IP address given with the line API listen and In another WSL terminal, you can test the following command : docker -H 172.20.5.64 run --rm hello-world. ){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 Searching around google, the answer that keeps popping up is to use the update-alternatives, which is the whole problem, I probably sound like I am quite fixated on the iptables package, but would you try reinstalling it? Microsoft offers a more detailed comparison in the docs. Let's first make a shared directory for the docker socket, and set permissions so that the docker group can write to it. Trying to understand how to get this basic Fourier Series. We're a place where coders share, stay up-to-date and grow their careers. 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. Here is the corrected version: ifconfig eth0 | grep -E "([0-9]{1,3}\. I have based these instructions on those, with some tweaks learned from real world testing. Of course, if you use Docker without Docker Desktop, as detailed in this article, then this does not apply.
