Docker Installation¶

Info

Here is the link for installing Docker Engine. I will only show how to install Docker Engine on Ubuntu, as installing Docker on Windows is very straightforward.

Install Docker Engine on Ubuntu¶

All the following steps are coming from this reference.

Setup Docker's apt repository

Bash

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
    "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
    $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

Install the Docker packages.

Bash

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Verify that the Docker Engine installation is successful by running the hello-world image.
Bash
```
sudo docker run hello-world
```

[Optional] Manage Docker as a non-root user.

Bash

sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

docker run hello-world # without sudo
