1 | ## fastai-rails - a docker setup for serving a deep learning model with a front-end component
2 |
3 | Steps to get up and running:
4 | 1. Install docker and docker-compose
5 | 2. Clone repository and cd into it
6 | 3. Run `docker-compose up` and wait for the images to be built
7 | 4. Navigate to `localhost` in your browser
8 |
9 | The frontend is a [rails](https://rubyonrails.org/) application. The API endpoint runs on [starlette](https://www.starlette.io/).
10 |
11 | This is a minimal setup created for demonstration purposes. The files of interest are:
12 | - [upload.html.erb](https://github.com/radekosmulski/fastai-rails/blob/master/web/app/views/images/upload.html.erb) - image upload form rendered when navigating to `localhost`
13 | - [images_controller.rb](https://github.com/radekosmulski/fastai-rails/blob/master/web/app/controllers/images_controller.rb) - rails controller handling the logic of reaching out to the API endpoint
14 | - [api.py](https://github.com/radekosmulski/fastai-rails/blob/master/api/api.py) - entire starlette app for the API endpoint
15 | - [show_results.html.erb](https://github.com/radekosmulski/fastai-rails/blob/master/web/app/views/images/show_results.html.erb) - template file for rendering the results to the user
16 | - [pets.ipynb](https://github.com/radekosmulski/fastai-rails/blob/master/train/pets.ipynb) - a jupyter notebook for training and saving the model
17 |
18 |
19 | I recorded a [walkthrough](https://youtu.be/BeJ80peD3Qs) where I follow a request starting with a user uploading an image to displaying the results.
