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. 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). Just run linux native. 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". Do so from a WSL window. Hi Pawel, thank you for your feedback. Same results more or less. [sudo] password for jai: Here is what you can do to flag bowmanjd: bowmanjd consistently posts content that violates DEV Community's For me, using WSL isn't a choice against Linux, but a choice to use Linux everywhere. If, however, when you launch WSL, you are still root, then set your new user as the default. Thankfully, there are official guides for installing Docker on various Linux distributions. 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. 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. 2.) Working with Windows Containers without Docker Desktop from PowerShell. My goal is to use the docker-cli in Windows (docker.exe), but using Linux containers, without the installation of Docker Desktop. You should see docker when you run the command groups to list group memberships." Get IP address in WSL2 My own .NET rest API runs as expected and so do other containers. I did. Through group membership, grant specific users privileged access to the Docker socket, Creates the shared docker directory for the socket and, For performance reasons, only bind mount from within the Linux filesystem. To do so, enter sudo visudo and add the following line (if your visudo uses vi or vim, then be sure to press "i" to begin editing, and hit ESC when done editing): Save and exit (":wq" if the editor is vi, or Ctrl-x if it is nano), and then you can test if sudo dockerd prompts for a password or not.

Note that Docker Desktop is only free individuals or for small companies. Isn't the deamon running inside wsl in any case? Have you managed to mount volumes from windows to docker image running in WSL2 ? Constantly learning to develop software. 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? ){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.

WARN[2021-11-06T15:39:08.509171500+05:30] Binding to IP address without --tlsverify is insecure and gives root access on this machine to everyone who has access to your network. WSL 2 uses an actual Linux kernel that allows Linux containers. I honestly haven't tried this with older versions of Debian. Assuming that the dockerd start script detailed above is saved in a file in WSL as $HOME/bin/docker-service and is executable (try chmod a+x $HOME/bin/docker-service), then the following line in your Powershell profile will launch dockerd automatically: Not sure where your Powershell profile is located?

So the reason I use Windows is because that's where the driver support is. Now it is possible to run Docker on Windows or MacOS. Previously with Docker Desktop we could run docker with -v %cd%/someFolder:/whatever or -v ./someFolder:/whatever, now we have to provide full path , like -v /mnt/c/full/local/path/to/someFolder:/whatever , which is user specific and will not run on team mate's computer Any thoughts how to overcome this ? 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.

The Docker engine includes tools that automate container image creation. If this fails due to network connectivity, see below. 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. But yes, I used WSL2 enough that moved to a second PC with native Linux. Ubuntu works correctly, I think because they still use iptables and not the nftables in Debian that Docker apparently doesn't really understand unless you configure nftables just right. 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.
