Installing OpenDrift
=============================================
Alternative 1: Using Mambaforge (or Miniforge) and Git (recommended)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1. Install `miniforge `_
2. Clone OpenDrift:
.. code-block:: bash
$ git clone https://github.com/OpenDrift/opendrift.git
$ cd opendrift/
3. Create environment with the required dependencies and install OpenDrift
.. code-block:: bash
$ mamba env create -f environment.yml
$ conda activate opendrift
$ pip install --no-deps -e .
This installs the OpenDrift package as an editable package. You can therefore directly make changes to the repository or fetch the newest changes with :code:`git pull`. You do not need to add OpenDrift to PYTHONPATH as long as you have the :code:`opendrift` environment activated.
Occasionally, new dependencies will be added to environment.yml. Then the local conda environment can be updated with:
.. code-block:: bash
$ mamba env update -f environment.yml
Alternative 2: Using Mambaforge (or Miniforge)
++++++++++++++++++++++++++++++++++++++++++++++
1. Install `miniforge `_
2. Set up a *Python 3* environment for opendrift and install opendrift
.. code-block:: bash
$ mamba create -n opendrift python=3 opendrift
$ conda activate opendrift
.. _source_install:
Modify install to use Git version
---------------------------------
If you later want to edit the OpenDrift source code, or be able to update from repository with `git pull`, the following two steps are necessary. This yields the same as Alternative 1.
3. Clone OpenDrift:
.. code-block:: bash
$ git clone https://github.com/OpenDrift/opendrift.git
$ cd opendrift/
4. Remove original package:
.. code-block:: bash
$ mamba remove --force opendrift
5. Install as editable:
.. code-block:: bash
$ pip install --no-deps -e .
Building and using the Docker image
+++++++++++++++++++++++++++++++++++
It is also possible to run OpenDrift in a `docker `_
container. You can either use the `pre-built images (each release or latest
master) `_:
.. code-block:: bash
$ docker run -it --rm opendrift/opendrift:latest
or if you want to re-build the image using your local version of opendrift, check out opendrift and make your changes, then:
.. code-block:: bash
$ git clone https://github.com/OpenDrift/opendrift.git
$ cd opendrift/
re-build the image:
.. code-block:: bash
$ docker build -t opendrift .
and run it:
.. code-block:: bash
$ docker run -it --rm opendrift
