Overview

========



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.



Documentation

=============



See the `user guide `__ for

installation and usage of the datacube, and for documentation of the API.



`Join our Slack `__ if you need help

setting up or using the Open Data Cube.



Please help us to keep the Open Data Cube community open and inclusive by

reading and following our `Code of Conduct `__.



Requirements

============



System

~~~~~~



-  PostgreSQL 10+

-  Python 3.9+



Developer setup

===============



1. Clone:



   -  ``git clone https://github.com/opendatacube/datacube-core.git``



2. 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



3. Install a develop version of datacube-core.



::



   cd datacube-core

   pip install --upgrade -e .



4. Install the `pre-commit `__ hooks to help follow ODC coding

   conventions when committing with git.



::



   pre-commit install



5. 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).



6. **(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



Developer setup on Ubuntu

~~~~~~~~~~~~~~~~~~~~~~~~~



Building a Python virtual environment on Ubuntu suitable for development work.



Install dependencies:



::



    sudo apt-get update

    sudo apt-get install -y \

        autoconf automake build-essential make cmake \

        graphviz \

        python3-venv \

        python3-dev \

        libpq-dev \

        libyaml-dev \

        libnetcdf-dev \

        libudunits2-dev



Build the python virtual environment:



::



    pyenv="${HOME}/.envs/odc"  # Change to suit your needs

    mkdir -p "${pyenv}"

    python3 -m venv "${pyenv}"

    source "${pyenv}/bin/activate"

    pip install -U pip wheel cython numpy

    pip install -e '.[dev]'

    pip install flake8 mypy pylint autoflake black
