## 使用单文件 FastAPI 构建 Docker 镜像 { #build-a-docker-image-with-a-single-file-fastapi }

如果你的 FastAPI 是单个文件，例如没有 `./app` 目录、只有 `main.py`，你的文件结构可能如下：

```
.
├── Dockerfile
├── main.py
└── requirements.txt
```

然后你只需要在 `Dockerfile` 中修改相应路径来复制该文件：

e}),odd:X(function(e,t){for(var n=1;n<t;n+=2)e.push(n);return e}),lt:X(function(e,t,n){var r;for(r=n<0?n+t:t<n?t:n;0<=--r;)e.push(r);return e}),gt:X(function(e,t,n){for(var r=n<0?n+t:n;++r<t;)e.push(r);return e})}}).pseudos.nth=b.pseudos.eq,{radio:!0,checkbox:!0,file:!0,password:!0,image:!0})b.pseudos[e]=B(e);for(e in{submit:!0,reset:!0})b.pseudos[e]=_(e);function G(){}function Y(e,t){var n,r,i,o,a,s,u,l=c[e+" "];if(l)return t?0:l.slice(0);a=e,s=[],u=b.preFilter;while(a){for(o in n&&!(r=y.exec(a))||(r&&(a=a.sl...
