# Flask

## Step 1: Ensure your app is Dockerised

ToyStack uses docker to deploy your application and will look for a `Dockerfile` in the top-level of your project structure.

You can either use your own `Dockerfile` or use the following template:

```docker
FROM python:3.8

ENV PYTHONUNBUFFERED 1
RUN mkdir /workdir
WORKDIR /workdir
COPY requirements.txt /workdir/
RUN pip install --upgrade pip wheel
RUN pip install -r requirements.txt
COPY . /workdir/

CMD ["python", "-m", "flask", "run", "--host=0.0.0.0", "--port=5000"]
```

## Step 2: Import your Git repository

Go to the [ToyStack Dashboard](https://dashboard.toystack.ai) and create a new project using your repository.

## Step 3: Input environment variables

{% hint style="info" %}
Please ensure the `Framework Preset` is set to `DOCKER`. The rest of the variables can be set as required for your project.

Also ensure the `PORT` number matches the one specified in your `Dockerfile`
{% endhint %}

For detailed instructions, please see the [Environment Variables](/get-started/environment-variables-setup.md) page.

## Step 4: Choose a plan
