sudo rm /usr/local/bin/docker-compose

sudo curl -k -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose


sudo chmod +x /usr/local/bin/docker-compose

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose


# 将用户添加到 docker 用户组中，以免每次执行 Docker 命令都需要 sudo
sudo usermod -aG docker $USER
newgrp docker

echo "配置 Docker 镜像加速器..."
sudo mkdir -p /etc/docker
echo '{
