docker install
Uninstall old versions
Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:
sudo apt-get remove docker docker-engine docker.io containerd runc
Install using the repository
Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.
Set up the repository
- Update the
aptpackage index and install packages to allowaptto use a repository over HTTPS:
sudo apt-get update
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg \
lsb-release
- Add Docker’s official GPG key:
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
nightlyortest(or both) after the wordstablein the commands below.
echo \
"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Install Docker Engine
- Update the
aptpackage index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
- Verify that Docker Engine is installed correctly by running the
hello-worldimage.
sudo docker run hello-world
nvidia-docker install
Setting up Docker
Docker-CE on Ubuntu can be setup using Docker’s official convenience script:
curl https://get.docker.com | sh \
&& sudo systemctl --now enable docker
Setting up NVIDIA Container Toolkit
Setup the stable repository and the GPG key:
distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
&& 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
Install the nvidia-docker2 package (and dependencies) after updating the package listing:
sudo apt-get update
sudo apt-get install -y nvidia-docker2
Restart the Docker daemon to complete the installation after setting the default runtime:
sudo systemctl restart docker
At this point, a working setup can be tested by running a base CUDA container:
sudo docker run --rm --gpus all nvidia/cuda:11.0-base nvidia-smi
docker command
HOW TO CREATE A DOCKER IMAGE FROM A CONTAINER
The Docker create command will create a new container for us from the command line:
sudo docker create --name nginx_base -p 80:80 nginx:alpine
Inspect Images
sudo docker images -a
Inspect Containers
sudo docker ps -a
We will use the docker cp command to copy this file onto the running container
sudo docker cp index.html nginx_base:/usr/share/nginx/html/index.html
Create an Image From a Container
sudo docker commit nginx_base hi_mom_nginx
python install
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.6
Change the Python3 default version in Ubuntu
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.6 2
sudo update-alternatives --config python
python3-pip install
sudo apt install python3-pip
echo "alias pip=pip3" >> ~/.bash_aliases
source ~/.bash_aliases
alias pip='python3.6 -m pip'
pip install --upgrade pip
