Alpine Dask Docker Images

Here we provide a few Docker_ images for running Dask_ on Alpine Linux_. These are designed to be as small as possible while still providing a good user experience.

Three images are provided:

• jcrist/alpine-conda |alpine-conda|

  A base image with miniconda_ installed.

• jcrist/alpine-dask |alpine-dask|

  An image for running both the dask schedulers and workers.

• jcrist/alpine-dask-notebook |alpine-dask-notebook|

  An image with all of the above, as well as Jupyter Notebook_ and JupyterLab_ installed.

These images can be used as is, or extended with additional packages by using them as a base image:

.. code-block:: docker

FROM jcrist/alpine-dask:1.2.2

# Add scikit-learn and numba, and cleanup afterwards
RUN /opt/conda/bin/conda install --freeze-installed -y \
        scikit-learn \
        numba \
    && /opt/conda/bin/conda clean -afy \
    && find /opt/conda/ -follow -type f -name '*.a' -delete \
    && find /opt/conda/ -follow -type f -name '*.pyc' -delete

Alternatively, additional packages can be installed at runtime via the EXTRA_CONDA_PACKAGES/EXTRA_PIP_PACKAGES environment variables:

.. code-block:: shell

$ docker run -e "EXTRA_CONDA_PACKAGES=scikit-learn numba" jcrist/alpine-dask dask-scheduler

These images should be drop-in usable with the existing Dask Helm Chart_, with the benefit of being much smaller images.
