Debian或Ubuntu中安装docker

最近需要频繁的配置环境，在Debian或Ubuntu中安装docker，所以写了个脚本。
installDocker.sh

#!/bin/bash

# Function to install Docker on Debian
install_docker_debian() {
    # Add Docker's official GPG key:
    sudo apt-get update
    sudo apt-get install -y ca-certificates curl gnupg
    sudo install -m 0755 -d /etc/apt/keyrings
    curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
    sudo chmod a+r /etc/apt/keyrings/docker.gpg

    # Add the repository to Apt sources:
    echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian $(. /etc/os-release && echo $VERSION_CODENAME) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
    sudo apt-get update
    sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
}

# Function to install Docker on Ubuntu
install_docker_ubuntu() {
    # Add Docker's official GPG key:
    sudo apt-get update
    sudo apt-get install -y ca-certificates curl gnupg
    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
    
    # Add the repository to Apt sources:
    echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
    sudo apt-get update
    sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
}

# Check if the OS is Ubuntu
if [ "$(lsb_release -is)" = "Ubuntu" ]; then
    install_docker_ubuntu
# Check if the OS is Debian
elif [ "$(lsb_release -is)" = "Debian" ]; then
    install_docker_debian
else
    echo "This script is for Ubuntu and Debian only."
    exit 1
