在Ubuntu Stream 8上安装和使用Docker可参考以下步骤：
sudo apt update && sudo apt upgrade。sudo apt install apt-transport-https ca-certificates curl software-properties-common。curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -。sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"。sudo apt install docker-ce docker-ce-cli containerd.io。sudo systemctl start docker，并设置开机自启：sudo systemctl enable docker。docker --version。docker pull ubuntu。docker run -it ubuntu /bin/bash。
