How to Install Docker and Docker Compose on Ubuntu and Raspian

1. sudo apt update
2. sudo apt install apt-transport-https ca-certificates curl gnupg lsb-release -y
3. Ubuntu: curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg –dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
4. Raspian/Debian: curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg –dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
5. Ubuntu: echo “deb [arch=$(dpkg –print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
6. Raspian: echo “deb [arch=$(dpkg –print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
7. sudo apt update
8. sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
9. sudo curl -L “https://github.com/docker/compose/releases/download/v2.9.0/docker-compose-$(uname -s)-$(uname -m)” -o /usr/local/bin/docker-compose
10. sudo chmod +x /usr/local/bin/docker-compose
11. sudo usermod -aG docker $USER

one-liner (Ubuntu):

sudo apt update && sudo apt install apt-transport-https ca-certificates curl gnupg lsb-release -y && curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg && echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null && sudo apt update && sudo apt install docker-ce docker-ce-cli containerd.io -y && sudo curl -L "https://github.com/docker/compose/releases/download/v2.9.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose && sudo usermod -aG docker $USER
