Editing Tutorials:Install the nVidia docker system (section)

== Install the correct docker version ==

Unfortunately, the docker version available with the usual package manager is incompatible with the nVidia docker tools. Thus, we have to install a version directly from the repositories. The following script (which needs sudo privileges to run) shows you how.

NOTE: The following scripts require <code>curl</code>, which may be not yet installed on your system (especially on a fresh Ubuntu). If so, install with <code>sudo apt-get install curl</code>.

<syntaxhighlight lang="bash">
#!/bin/bash
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   bionic \
   stable"

sudo apt-get update
sudo apt-get install -y docker-ce
</syntaxhighlight>

Note that the string "bionic" is the output of the command "lsb_release -cs". If you have another version of Ubuntu than 18.04, you can try to replace "bionic" with the output of this command, but it might not be supported. On a derivative Linux, this does not work, and you need to find out the correct Ubuntu lsb release by consulting their documentation. Do the same for similar occurences in scripts further below.

You also need a more recent version of a tool called "docker-compose", more on this later.
Install the latest version like this:

<syntaxhighlight lang="bash">
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
</syntaxhighlight>

Post install, you have to allow docker access for your account. Note that this comes with a bunch of privileges which are essentially equivalent to admin rights on your machine. Thus, some guides recommend to set up a special user account for this. Anyway, assign the respective rights by adding your user to the docker group:

<syntaxhighlight lang="bash">
sudo usermod -aG docker $USER
</syntaxhighlight>

After that, it is at least necessary to log out and back in to update the privileges, but a reboot also can not hurt.
