How To Install Docker and NVIDIA-Docker on Ubuntu 19.04


Being able to get Docker and the NVIDIA-Docker runtime working on Ubuntu 19.04 makes this new and (currently) mostly unsupported Linux distribution a lot more useful. In this post I'll go through the steps that I used to get everything working nicely.

First my "standard'ish" disclaimer for unsupported install hacks,

Docker is a wonderful computing tool. It's displacing tradition servers and virtual machines in the data-center. It is also great on your workstation! It makes it possible to work with a variety of applications and frameworks that might be very difficult, incompatible or not even possible to directly install on your workstation.

I've been writing posts about docker and nvidia-docker since Feb. 2017. That was when NVIDIA launched NGC (NVIDIA GPU Cloud). I wrote a series of 5 posts in starting in Feb 2018 that form a guide to configuring docker and nvidia-docker for workstation use. Those posts are a good source for more detailed discussion on the steps we'll go through in this post. The 5th post in that series has links back to the earlier posts so for more details check them out.

How-To Setup NVIDIA Docker and NGC Registry on your Workstation – Part 5 Docker Performance and Resource Tuning

These are the steps we'll go through for the install and setup,

  • Setup the nvidia-docker repository
  • Setup the docker repository
  • Install and test docker
  • Install and test the nvidia-docker2 runtime
  • Configure docker group and "User Namespaces"
  • Tune docker for good performance with nvidia-docker compute jobs

Setup the nvidia-docker2 repository

To install docker and nvidia-docker on Ubuntu 19.04 we will need to do some manual repository configuration. There is a reason for this that you will see below.

nvidia-docker and docker-ce have to be in sync. the most recent nvidia-docker repositories are for Ubuntu 18.04 (and that makes sense). The code-base however is keep updated and built against the most recent docker build.

I'm going to start by configuring the NVIDIA-docker repositories first so we can look at the version to see what what docker repository and version will be needed.

1) Go to to see the latest supported Ubuntu version.

As of this writing supported Ubuntu versions are 14.04, 16,04, and 18.04 (all long term support versions). We will need to configure repos for Ubuntu 18.04 since it is the most recent.

2) Add the repo key,

curl -s -L | sudo apt-key add -

3) Configure the needed repos by hand.

If you try to use the script on the install page it will fail because it will return 19.04 as VERSION_ID. It's easy to just add the repos by hand.

Using sudo and your editor of choice create the following file,


add the following lines to it,

deb$(ARCH) /
deb$(ARCH) /
deb$(ARCH) /

Save that file and refresh the package list,

sudo apt-get update

4) Check the installable versions of nvidia-docker2.

This is what I got when I wrote this post,

kinghorn@u19:~$ apt-cache madison nvidia-docker2​​​​​​​

nvidia-docker2 | 2.0.3+docker18.09.5-3 | Packages
nvidia-docker2 | 2.0.3+docker18.09.5-2 | Packages
nvidia-docker2 | 2.0.3+docker18.09.4-1 | Packages
nvidia-docker2 | 2.0.3+docker18.03.1-1 | Packages
nvidia-docker2 | 2.0.3+docker17.12.1-1 | Packages

The "+docker …" part of those lines is the corresponding docker version that needs to be installed for that version of nvidia-docker. The most recent version in this case is "docker18.09.5-3". Keep in mind that this is from a repo for Ubuntu 18.04, also know as "bionic". That will be important.

Setup the docker repository, Install and check docker

We'll mostly follow the install described here except that we will be specific about the version and Ubuntu release.

1) Install some required packages, (they may already be installed)

sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

2) Add and check the docker key,

curl -fsSL | sudo apt-key add -

sudo apt-key fingerprint 0EBFCD88

The fingerprint should match "9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88"

3) Now add the repository for "bionic"

sudo add-apt-repository "deb [arch=amd64] bionic stable"

Note: I explicitly used "bionic" rather than $(lsb_release -cs) (that would return "disco"). We have to use "bionic" in the repository to keep apt-get from failing during the nvidia-docker2 install.

4) Check the installable docker versions,

kinghorn@u19:~$ apt-cache madison docker-ce

docker-ce | 5:18.09.5~3-0~ubuntu-bionic | bionic/stable amd64 Packages
docker-ce | 5:18.09.4~3-0~ubuntu-bionic | bionic/stable amd64 Packages
docker-ce | 18.06.0~ce~3-0~ubuntu | bionic/stable amd64 Packages
docker-ce | 18.03.1~ce~3-0~ubuntu | bionic/stable amd64 Packages

You see that the most recent version is tagged as "5:18.09.5~3-0~ubuntu-bionic". That will match up with the nvidia-docker2 version "2.0.3+docker18.09.5-3".

5) Install docker (with the specified version numbers).

sudo apt-get install docker-ce=5:18.09.5~3-0~ubuntu-bionic docker-ce-cli=5:18.09.5~3-0~ubuntu-bionic

Note: "" is independent of docker but included in that repository.

6) Check docker,

sudo docker run --rm hello-world

That should pull and run the hello-world container from Docker Hub. We will add user configuration later.

Install and check nvidia-docker2

1) Install nvidia-docker2 (using the version that will match with the docker install)

sudo apt-get install nvidia-docker2=2.0.3+docker18.09.5-3

2) Restart docker to enable the configuration for the nvidia-docker2 runtime.

sudo systemctl restart docker.service

3) Check nvidia-docker2

sudo docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi

That will pull the latest nvidia cuda container from Docker Hub, run the nvidia-smi command and exit.

(Recommended) Disable the repositories you installed from

If your docker build version and nvidia-docker build version get out of sync because of automatic system updates then your install will break. You can use the "apt hold" mechanism or simply comment out the repository lines at the end of /etc/apt/sources.list and in /etc/apt/sources.list.d/nvidia-docker.list

Of course, this means that if there are new releases that you want to upgrade to you will need to revert the repository configuration and recheck version numbers. But, this would be a good thing!

Setup docker for your personal user account with User Namespaces and add performance optimizations

1) Add your user name to the docker group

sudo usermod -aG docker your-user-name

Note: You will need to logout and back in for this to take effect.

3) Add your user and group id's as "subordinate id's".

See How-To Setup NVIDIA Docker and NGC Registry on your Workstation – Part 3 Setup User-Namespaces.

– Add a subordinate id

sudo usermod -v 1000-1000 kinghorn

– Add a subordinate group

sudo usermod -w 1000-1000 kinghorn

Note: Of course, use your own user-name and id. You can use the id command to check your user and group id.

4) Setup the docker configuration file for your User Namespace, the nvidia-docker runtime, and compute performance optimizations.

You cannot even access the docker configuration directory unless you are "root" so before you edit the file /etc/docker/daemon.json do,

sudo -s

cd /etc/docker

to give yourself a root shell. Then save a copy of the docker daemon.json config file and create a new one with the following JSON.

Note: Be sure to to change that "kinghorn" to your own user name!

    "runtimes": {
        "nvidia": {
            "path": "/usr/bin/nvidia-container-runtime",
            "runtimeArgs": []
    "userns-remap": "kinghorn",
    "default-shm-size": "1G",
    "default-ulimits": {
	     "memlock": { "name":"memlock", "soft":  -1, "hard": -1 },
	     "stack"  : { "name":"stack", "soft": 67108864, "hard": 67108864 }

Docker will read this file on startup and add the nvidia-runtime so you can use your NVIDIA GPU with docker.

This config then sets up your "user" in the docker User Namespace. That means that even though you see a root prompt in a docker container any files you create will belong to you in your system namespace. Please reed the post I mentioned in step 3) of this section to understand the full meaning of this.

The last part ot the config changes the (pitiful) default performance parameters so the you can run large GPU accelerated compute jobs. The post I linked in the "Introduction" has details of that setup.

5) Restart docker

sudo systemctl restart docker.service


You now have what you will hopefully find to be a very useful docker configuration on your Ubuntu 19.04 workstation.

If you want to use some of the nice containers that NVIDIA has put together on NGC then go to there site and register for access. You could then, for example start up their TensorFlow container with something like,

docker run --runtime=nvidia --rm -it -v $HOME/projects:/projects

Note: The -v $HOME/projects:/projectspart of that line is mapping a directory named "projects" in your users home directory to the directory "/projects" in the container. Any files created there will be owned by your user and remain there after you exit from the container instance.

I hope this gets you going with docker on Ubuntu 19.04. If you have trouble and decide to go back to Ubuntu 18.04 the procedure in this post will work for that too! (And, it would still be good to be careful about the version number matching.)
