Prerequisites Docker Installation on Ubuntu ![]() In this article, you’ll learn how to install Docker on Ubuntu. Multiple containers run on the same hardwareīefore learning about this technology, the first step is to install it.But now it does provide the init.d script, so you can now run sudo service docker start as you originally tried.Īlternatively, nVidia provides setup instructions which use the script.Docker is the modern platform for high-velocity innovation-a tool that is used to automate the deployment of applications in lightweight containers so that applications can work efficiently in different environments.Ī few quick notes about Docker:docker-installation-on-ubuntu-article However, it attempts to use Systemd, which fails on WSL. Those instructions do assume that the installation script will start the Docker daemon. However, if you do want to use the open-source edition, you can do that using (mostly) the official Docker instructions for Ubuntu. And that, in turn, helps fund Docker's open-source initiatives. Some folks seem to be wanting to move away from it as a result, but I would propose (purely my opinion) that if you work for a large company, they will often pay for these sorts of tools. There has been a license change recently that requires a paid subscription if you are using it in a large company. It's a convenience method that handles all of the other stuff below automatically for you.It handles automatic upgrades (although some might not consider that necessarily an advantage).It provides a GUI dashboard of containers and volumes.It can be shared amongst multiple WSL2 instances.Docker Desktop has tight integration with WSL, and provides some nice-to-have features that you don't get with the open-source Docker version: So let's start by uninstalling docker.io and the dependencies it installed: sudo apt remove docker.io Either that, or one that knows how to start on its own under WSL. It's much better to have a Docker version that provides an init script for the service command. However, WSL doesn't support Systemd (without a lot of hackery, at least). Many packages used to also provide the legacy init script. Ubuntu uses Systemd, and the docker.io installs the Systemd unit file for the Docker service. Presumably, it was removed from the docker.io package sometime between the time the instructions were written (and presumably valid) and now. That's the same init script that the service command attempts to run. You can see the problem in /var/log/apt/term.log during the installation of the docker.io package: invoke-rc.d: unknown initscript, /etc/init.d/docker not found. I've been able to reproduce this using the (apparently outdated) Canonical instructions you linked. Nvidia-docker2 is already the newest version (2.8.0-1).Ġ upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Here are the outputs from the mentioned commands I ran: service -status-allĬommand: sudo apt update & sudo apt install -y nvidia-docker2 Please help me figure out how to properly install CUDA, I am trying to set up opencv with GPU support for a project I am working on in image processing. I've also tried to check if the docker service is available at all using service -status-all and didn't see it in the results. I did follow the instructions up to the point where this command is in the tutorial, and the results of running sudo apt update & sudo apt install -y nvidia-docker2 seem successful. I am trying to install CUDA according to the instructions here: Īnd I am getting a docker: unrecognized service message when running command sudo service docker stop.
