Configure Your Lightning Cloud App¶

Audience: Users who want to control Lightning App files on the cloud.

Ignore file uploads to Lightning cloud¶

Running Lightning Apps on the cloud will upload the source code of your app to the cloud. You can use .lightningignore file(s) to ignore files or directories while uploading. The .lightningignore file follows the same format as a .gitignore file.

For example, the source code directory below with the .lightningignore file will ignore the file named model.pt and directory named data_dir.

.
├── README.md
├── app.py
├── data_dir
│    ├── image1.png
│    ├── image2.png
│    └── ...
├── .lightningignore
├── requirements.txt
└── model.pt

~/project/home ❯ cat .lightningignore
model.pt
data_dir

A sample .lightningignore file can be found here.

If you are a component author and your components creates local files that you want to ignore, you can do:

class MyComponent(L.LightningWork):  # or L.LightningFlow
    def __init__(self):
        super().__init__()
        self.lightningignore = ("model.pt", "data_dir")

This has the benefit that the files will be ignored automatically for all the component users, making an easier transition between running locally vs in the cloud.

Structure app files¶

We recommend your app contain the following files:

.
├── .lightning        (auto-generated- contains Lightning configuration)
├── .lightningignore  (contains files not to upload to the cloud)
├── app.py
├── README.md         (optional- a markdown description of your app)
└── requirements.txt  (optional- contains all your app dependencies)
