Official Portal: Installing Docker Engine on Ubuntu | Docker Documentation
1. Set up the repository
1. Update package index and install packages to allow HTTPS based repositories
sudo apt-get update sudo apt-get install ca-certificates curl gnupg
2. 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
3. Set up the repository with the following command
echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu\ "$(. /etc/os-release & amp; & amp; echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
2. Install the Docker engine
1. Update package index
sudo apt-get update
2. Install Docker Engine, containerd and Docker Compose
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
3. Verify that the Docker Engine installation was successful by running the image
sudo docker run hello-world
The following indicates that the docker installation is successful
Install docker-compose
1. Update and install
sudo apt-get update sudo apt-get install docker-compose-plugin
2. Verify that the installation is successful
docker compose version

sudo usermod -aG docker $USER
Set Docker image acceleration
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://XXXXXXXX.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
