Getting started

Get Started with DVC

Prerequisites

As a prerequisite for using DVC, you must have a Git repository initialized :

git clone https://gitlab.develop.eoepca.org/sharinghub-test/sen1floods11-dataset.git

Authenticate DVC

Configure your authentication (will be only stored locally)

dvc remote modify --local workspace access_key_id 'mysecret'
dvc remote modify --local workspace secret_access_key 'mysecret'

Tracking data

Working inside an initialized project directory, let's pick a piece of data to work with. We'll use an example very_big_file.txt file, in the data directory.

echo "very big content" > data/very_big_file.txt

Use dvc add to start tracking the dataset file:

dvc add data/very_big_file.txt

DVC stores information about the added file in a special .dvc file named data/very_big_file.txt.dvc. This small, human-readable metadata file acts as a placeholder for the original data for the purpose of Git tracking.

Next, run the following commands to track changes in Git:

git add data
git commit -m "chore: add raw data"
dvc push
git git push --set-upstream origin main
