Development

Freesound is composed of a number of different services which can be run and orchestrated using Docker. The main service is provided by the web container which runs the Freesound Django application. Check out this blog post for some information about the Freesound technology stack. If you're going to do development on Freesound, please check the DEVELOPERS file for some guidelines.

Below are instructions for setting up a local Freesound installation for development. It is assumed that you have a working Docker installation.

Setting up Freesound for development in 13 easy steps

1. Clone source code repository

   git clone [email protected]:MTG/freesound.git
   cd freesound
   

2. Create a directory named freesound-data inside the repository folder

   mkdir freesound-data
   

3. Download the Freesound development data zip file (~20GB) and uncompress it inside freesound-data. You should get permission to download this file from Freesound admins. File structure should look like this:

   freesound/
   freesound/freesound-data/
   freesound/freesound-data/analysis/
   freesound/freesound-data/avatar/
   ...
   

4. Download Freesound development similarity index and the Freesound tag recommendation models and place their contents under freesound-data/similarity_index/ and freesound-data/tag_recommendation_models directories respectively (you'll need to create the directories). You should get permission to download these files from Freesound admins.

5. Rename freesound/local_settings.example.py file so you can customise Django settings if needed and create a .env file with your local user UID and other useful settings. These other settings include COMPOSE_PROJECT_NAME and LOCAL_PORT_PREFIX which can be used to allow parallell local installations running on the same machine (provided that these to variables are different in the local installations), and FS_BIND_HOST which you should set to 0.0.0.0 if you need to access your local Fresound services from a remote machine.

   cp freesound/local_settings.example.py freesound/local_settings.py
   echo FS_USER_ID=$(id -u) > .env
   echo COMPOSE_PROJECT_NAME=freesound >> .env
   echo LOCAL_PORT_PREFIX= >> .env
   echo FS_BIND_HOST= >> .env
   

6. [Optional] Create API credentials for the 3rd party services listed below and add them to your own freesound/local_settings.py file (check settings.py to know the config parameter names that you need to fill in):

   • Mapbox
   • Recaptcha

7. Build the base Freesound Docker image

   make -C docker
   

8. Build all Docker containers. The first time you run this command can take a while as a number of Docker images need to be downloaded and things need to be installed and compiled.

   docker-compose build
   

9. Download the Freesound development database dump (~50MB), run the database container and load the data into it. You should get permission to download this file from Freesound admins.

   docker-compose up -d db
   docker-compose run --rm db psql -h db -U freesound  -d freesound -f /freesound-data/db_dev_dump/freesound_dev_db-2018-01-12-anonymised.sql
   

10. Update database by running Django migrations

    docker-compose run --rm web python manage.py migrate
    

11. Create a superuser account to be able to login to the local Freesound website and to the admin site

    docker-compose run --rm web python manage.py createsuperuser
    

12. Run services 🎉

    docker-compose up
    

When running this command, the most important services that make Freesound work will be run locally. This includes the web application and database, but also the search engine, cache manager, queue manager and asynchronous workers including audio processing. You should be able to point your browser to http://localhost:8000 and see the Freesound website up and running!

13. Build the search index so you can search for sounds and forum posts

    # Open a new terminal window so the services started in the previous step keep running
    docker-compose run --rm web python manage.py reindex_search_engine_sounds
    docker-compose run --rm web python manage.py reindex_search_engine_forum
    

After following the steps you'll have a functional Freesound installation up and running, with the most relevant services properly configured. You can run Django's shell plus command like this:

docker-compose run --rm web python manage.py shell_plus

Because the web container mounts a named volume for the home folder of the user running the shell plus process, command history should be kept between container runs :)

14. (extra step) The steps above will get Freesound running, but to save resources in your local machine some non-essential services will not be started by default. If you look at the docker-compose.yml file, you'l see that some services are marked with the profile analyzers or all. These services include sound similarity, search results clustering and the audio analyzers. To run these services you need to explicitely tell docker-compose using the --profile (note that some services need additional configuration steps (see Freesound analysis pipeline section in DEVELOPERS.md):

    docker-compose --profile analyzers up   # To run all basic services + sound analyzers
    docker-compose --profile all up         # To run all services
    

Running tests

You can run tests using the Django test runner in the web container like that:

docker-compose run --rm web python manage.py test --settings=freesound.test_settings
