hostess 0.10.1

hostess
overview
hostess provides lightweight, Pythonic interfaces to distributed resources,
system processes, and Python internals. It includes high-level modules that
provide special functionality for working with EC2 instances and S3 buckets,
and a framework (station) for workflow coordination -- along with all their
lower-level building blocks.
hostess reduces syntactic headaches and boilerplate while still
allowing low-level manipulation and, more broadly, still feeling like code.
hostess has a special emphasis on fitting intuitively and idiomatically into
common data science and scientific analysis workflows, but it is fundamentally
a general-purpose utility and administration library.
installation
hostess is available on PyPI and conda-forge. We recommend installing it
into a Conda environment using conda:
conda install -n my_environment -c conda-forge hostess.
The conda-forge package installs all optional dependencies other than those
for tests and Notebooks. If you require more granular control over
dependencies, please install from source.
documentation
Examples for working with EC2 instances can be found in this jupyter notebook.
Examples for working with S3 buckets can be found in this jupyter notebook.
You can find an API reference and full changelog on readthedocs.

compatibility

hostess's core features are closely linked to the shell, so it is
only fully compatible with Unix-scented operating systems. Linux and MacOS
count, as does Windows Subsystem for Linux (WSL). Windows outside of WSL
doesn't.
Some hostess modules require network access, specifically ssh and the
aws submodules. The aws submodules also require an AWS account. See the
example Notebooks for more details on this.
hostess requires Python >= 3.9.
hostess is very lightweight. If a machine has enough resources to run
a Python interpreter, it can probably run hostess.
hostess.station is not fully compatible with MacOS or WSL. MacOS and WSL
compatibility is planned. All other parts of hostess are compatible with
MacOS and WSL.

cautions
hostess is a reliable and fairly feature-complete beta in active use on
multiple projects. However, we do not yet guarantee interface stability or
backwards compatibility.
Also, as with any system administration software, we recommend using it very
carefully.
tests
hostess includes a simple test suite compatible with pytest. More
comprehensive tests are planned. (In particular, non-local networking features
currently lack test coverage.) You can run the tests by executing pytest -s
in the root directory. The -s flag is mandatory because pytest captures
stdout by default, which breaks some hostess features covered by the tests.
Tests require two additional dependencies: pytest and pillow.
licensing
You can do almost anything with this software that you like, subject only to
the extremely permissive terms of the BSD 3-Clause License.
