Reference pre-built binary in vendor folder

dkoutsou commented 7 years ago

I have written an API using chalice that does some processing of audio files. For the processing I am using ffmpeg. I have a pre-built version of ffmpeg included in the /vendor folder and I want to call this executable (using subprocess) from a function that is located in the /chalicelib folder. Is this possible? If so, what is the structure of the application inside the lambda in order to include the absolute path in the subprocess call?

If your chalice directory looks like this:

.
├── app.py
├── before
├── chalicelib
│   └── customcode
│       └── __init__.py
├── requirements.txt
└── vendor
    ├── fake.so
    └── vendored_lib
        └── __init__.py

Then your deployment package will look like this:

.
├── app.py
├── chalice
│   ├── __init__.py
│   └── app.py
├── chalicelib
│   └── customcode
│       └── __init__.py
├── fake.so
├── vendored_lib
│   └── __init__.py

The top app.py is your code.

@stealthycoin How should .so files be placed within vendor/ in order for them to get loaded properly on the deployed application when using automatic lambda layers?

aws / chalice
