The Open Data Cube Core provides an integrated gridded data analysis environment for decades of analysis ready earth observation satellite and related data from multiple satellite and other acquisition systems.
See the user guide for installation and usage of the datacube, and for documentation of the API.

- PostgreSQL 10+
- Python 3.9+
- Clone:
git clone https://github.com/opendatacube/datacube-core.git
- Create a Python environment for using the ODC. We recommend Mambaforge as the easiest way to handle Python dependencies.
mamba env create -f conda-environment.yml conda activate cubeenv
- Install a develop version of datacube-core.
cd datacube-core pip install --upgrade -e .
- Install the pre-commit hooks to help follow ODC coding conventions when committing with git.
pre-commit install
- Run unit tests + PyLint
Install test dependencies using:
pip install --upgrade -e '.[test]'
If install for these fails, please lodge them as issues.
Run unit tests with:
./check-code.sh
(this script approximates what is run by GitHub Actions. You can alternatively run
pytest
yourself).
(or) Run all tests, including integration tests.
./check-code.sh integration_tests
- Assumes a password-less Postgres database running on localhost called
pgintegration
- Otherwise copy
integration_tests/integration.conf
to~/.datacube_integration.conf
and edit to customise. - For instructions on setting up a password-less Postgres database, see
- the developer setup instructions.
Alternatively one can use the opendatacube/datacube-tests
docker image to run
tests. This docker includes database server pre-configured for running
integration tests. Add --with-docker
command line option as a first argument
to ./check-code.sh
script.
./check-code.sh --with-docker integration_tests
To run individual tests in a docker container
docker build --tag=opendatacube/datacube-tests-local --no-cache --progress plain -f docker/Dockerfile . docker run -ti -v $(pwd):/code opendatacube/datacube-tests-local:latest pytest integration_tests/test_filename.py::test_function_name
