7/2/2023 0 Comments Sudo service docker start![]() ![]() On Ubuntu under WSL2, you need to first start the daemon with: sudo service docker start In short, the Docker Engine package under Ubuntu attempts to start the daemon via Systemd, which (as mentioned above) isn't running by default on WSL. While it is possible to install and run Docker Engine manually in a WSL2 instance, there's one critical difference there that I explain in this answer. I cover some reasons why this is preferable in this Stack Overflow answer. "since Linux natively supports containers, I should install Docker Engine" on Linux.įirst, for most users, the recommended way of installing Docker in Windows/WSL2 is via Docker Desktop for Windows. I've attempted to write up as many differences and limitations as I can think of in this Ask Ubuntu answer. For instance, there's no Systemd running by default in a Docker Ubuntu container. ![]() a Docker Ubuntu container), there are differences in how you set up services when compared to a physical or virtual machine. It's actually more like running Ubuntu in a container, because it really is. I'm quite confused by all the layers of software involved here. If so, then is there some other way I should be "installing Docker" so that Docker commands like sudo docker run hello-world can be run from within my Ubuntu WSL? Perhaps are the instructions at only meant for "Ubuntu natively installed on a host PC" and not for Ubuntu WSL running on a Windows PC? User 10212 0.0 0.0 8164 732 pts/2 S+ 21:44 0:00 grep -color=auto containerdĬan someone please help me understand what has gone wrong, and if there is corrective action I can take to successfully install Docker in this Ubuntu WSL app on my Windows PC? Ls: cannot access '/var/run/docker.sock': No such file or directory There is no /var/run/docker.sock and I don't think the Docker daemon is running: $ ls -l /var/run/docker.sock My naive understanding is that "since Linux natively supports containers, I should install Docker Engine" on Linux.īut when I try to verify that Docker Engine is installed correctly by running the hello-world image, I get the following error: $ sudo docker run hello-worldĭocker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Trusting this claim that this Ubuntu WSL is equivalent to a Linux development environment, I now want to run Docker in this Ubuntu instance. ![]() When I explore within the running Ubuntu app, it generally feels like the normal Linux I'm accustomed to: the shell appears to be bash, and I have access to executables like git, curl, man, etc. My naive understanding is that this Ubuntu "app" is equivalent to a Linux development environment. If due to some reason the first method is not working then we can go for the SNAP packages.I've recently installed Ubuntu 22.04 WSL on my Windows 10 PC. Here we are installing a container using Ubuntu’s latest image. Now, it’s time to pull an image from Docker Hub to test everything is fine or not. So far we have installed and running up the docker on our Manjaro successfully. For that use this command: sudo usermod -aG docker $USERĥ. To solve this, we need to add our local user to the Docker group. To check docker versions and other information- docker -versionīy default, we need to use sudo with Docker command to create a container, delete, info, etc. sudo systemctl enable -now dockerįor getting the status- sudo systemctl status docker Once the installation is completed, the next is to start its service and also enable the same so that after every reboot, the Manjaro can automatically start the Docker Service. Packages to install Docker are already there on the official repository of Manjaro, thus no need to add anything extra, just go for the command given below and you are good to go. Run system updateįirst of all, use the Pacman and run the system update command that not only installs the available packages but also refreshes the repository. ![]() Install Docker using SNAP Steps to install Docker Container on Manjaro Linux 1. ![]()
