Preparation
Before we begin, make sure you're logged in with a user account that has sudo privileges.
Update System Packages
Update your package list to ensure you have the latest versions of packages:
sudo apt update && sudo apt upgrade -y
Install Docker Prerequisites
Install the necessary packages for Docker setup:
sudo apt install -y apt-transport-https ca-certificates curl software-properties-common
Setup Docker Repository
- 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
- Add the Docker Repository:
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
Install Docker and Docker Compose
- Update Package List Again:
sudo apt update
- Install Docker Engine, CLI, Containerd, and Additional Tools:
sudo apt install -y docker-ce docker-ce-cli containerd.io python3-bs4 python3-requests docker-compose
Verify Installation
Check if Docker and Docker Compose are installed correctly:
docker --version
docker-compose --version
Configure User Permissions
To run Docker commands without sudo, add your user to the docker group:
sudo usermod -aG docker $USER
Note: After adding your user to the docker group, you'll need to log out and log back in for the changes to take effect. If you do not log out and back in, Or you do not add your $USER to the docker group, you will be required to use sudo in some cases. such as ..
a way to apply group changes without logging out and back in - tip:
exec sudo su -l $USER
This command will replace your current shell with a new login shell for your user, which will have the updated group memberships. Both of these methods will apply the group changes immediately, allowing you to use LXD commands without having to log out and back in.
Remember, these changes only apply to the current terminal session. If you open a new terminal window, you might need to run the command again or log out and back in for the changes to take effect system-wide.
