1、配置阿里云镜像（用于拉取镜像加速）
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
2、拉取镜像
docker pull python:3.8
docker pull python:3.10
docker images
docker run -it --name streamlit python:310 /bin/bash
