Docker

Install docker on ubuntu

1.Uninstall old versions

bash sudo apt-get remove docker docker-engine docker.io containerd runc Check that it has been completely removed from your system: bash docker -v If the a message like Docker version 20.10.14, build a224086 is displayed, try following commands to remove it: bash sudo apt-get purge -y docker-engine docker docker.io docker-ce docker-ce-cli sudo apt-get autoremove -y --purge docker-engine docker docker.io docker-ce The above commands will not remove images, containers, volumes, or user created configuration files on your host. If you wish to delete all images, containers, and volumes run the following commands: bash sudo rm -rf /var/lib/docker /etc/docker sudo rm /etc/apparmor.d/docker sudo groupdel docker sudo rm -rf /var/run/docker.sock

2.Install using the repository

First, make the following configurations to avoid internet problems in the next levels: bash sudo nano /etc/apt/apt.conf.d/proxy.conf Then copy and save Acquire::http::Proxy::download.docker.com "http://fodev.org:8118/"; Update the apt package index and install packages to allow apt to use a repository over HTTPS: bash sudo apt-get update sudo apt-get install \ ca-certificates \ curl \ gnupg \ lsb-release Add Docker’s official GPG key: bash curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg Use the following command to set up the stable repository. To add the nightly or test repository, add the word nightly or test (or both) after the word stable in the commands below. bash echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version: bash sudo apt-get update sudo apt-get install docker-ce docker-ce-cli containerd.io Install latest version of Docker Engine: bash sudo apt-get install docker-ce Set proxy to be able of pulling images: ```bash mkdir -p /etc/systemd/system/docker.service.d sudo nano /etc/systemd/system/docker.service.d/http-proxy.conf

[Service] Environment="HTTPS_PROXY=http://fodev.org:8118"

systemctl daemon-reload systemctl restart docker Verify that Docker Engine is installed correctly by running the hello-world image.bash sudo docker run hello-world ```

3.Add registry-mirror

bash sudo nano /etc/docker/daemon.json Copy and save
{ "registry-mirrors": [ "https://docker.jamko.ir" ], "insecure-registries": [], "debug": true, "experimental": false } bash systemctl daemon-reload systemctl restart docker

Installing NVIDIA Container Toolkit for docker

1.Setting up Docker

Docker-CE on Ubuntu can be setup using Docker’s official convenience script:

bash curl https://get.docker.com | sh \ && sudo systemctl --now enable docker

2.Setting up NVIDIA Container Toolkit

Setup the package repository and the GPG key: bash distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \ && curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \ && curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \ sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \ sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

To get access to experimental features and access to release candidates, you may want to add the experimental branch to the repository listing: bash curl -s -L https://nvidia.github.io/libnvidia-container/experimental/$distribution/libnvidia-container.list | \ sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \ sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list If you got following error: Unsupported distribution! Check https://nvidia.github.io/libnvidia-container Use the following command to solve it, otherwise ignore this step: ```bash distribution=ubuntu18.04

Add the package repositories

curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add - curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit sudo systemctl restart docker ```
Install the nvidia-docker2 package (and dependencies) after updating the package listing:

```bash sudo apt-get update

sudo apt-get install -y nvidia-docker2 ``` Restart the Docker daemon to complete the installation after setting the default runtime:

bash sudo systemctl restart docker At this point, a working setup can be tested by running a base CUDA container: bash sudo docker run --rm --gpus all nvidia/cuda:11.0-base nvidia-smi This should result in a console output shown below:
