# Installation
### Docker
It is highly recommended that you use the official Docker image to run Pastey. To do so, simply run:
```
$ docker run -d -p 5000:5000 -v /path/to/local/dir:/app/data cesura/pastey:latest
```
Change **/path/to/local/dir** to a local folder you would like to use for persistent paste storage. It will be mounted in the container at **/app/data**.

Pastey will then be accessable at *http://localhost:5000*

### Docker (non-AVX processor)
If your processor does not have support for AVX instructions, the "latest" image will fail to run. This is due to a decision by Tensorflow to enable this compile flag by default in version 1.5+. However, Anaconda's distribution of Tensorflow supports older architectures even in the 2.x line. You can instead use the image tagged ***latest-conda***:
```
$ docker run -d -p 5000:5000 -v /path/to/local/dir:/app/data cesura/pastey:latest-conda
```

### Local
Requirements:
* Python 3.8
* AVX-enabled processor (or a Python environment configured to use Anaconda's Tensorflow)

```
$ git clone https://github.com/Cesura/pastey.git && cd pastey
$ pip3 install -r requirements.txt
$ python3 app.py 
```

### Docker configuration
For Docker environments, it is recommended that the options be passed to the container on startup: 
```
$ docker run -d -p 5000:5000 -e PASTEY_LISTEN_PORT=80 -e PASTEY_BEHIND_PROXY="True" cesura/pastey:latest
```
