Tested in Ubuntu Server 24.x

Update and install dependencies:

sudo apt update
sudo apt install ca-certificates curl gnupg lsb-release -y

Add Docker’s official GPG key:

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

Set up the repository:

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

Install Docker Engine:

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

Create base folder (suggest to put in home folder or /opt folder) create as regular user, not root if in home folder

sudo cd /opt
sudo mkdir docker

However, to make your life easier when using Docker as a regular user (if under /opt), there is a specific way to handle the permissions.

Change Ownership to your user, this is the “secret sauce.” It allows your regular user (and Webmin's file manager) to edit the config files without needing sudo every single time.

    sudo chown -R $USER:$USER /opt/docker
