Hetzner Cloud Python

Official Hetzner Cloud python library.

The library's documentation is available at hcloud-python.readthedocs.io, the public API documentation is available at docs.hetzner.cloud.

Important

Make sure to follow our API changelog available at docs.hetzner.cloud/changelog (or the RSS feed available at docs.hetzner.cloud/changelog/feed.rss) to be notified about additions, deprecations and removals.

Usage

Install the hcloud library:

pip install hcloud

For more installation details, please see the installation docs.

Here is an example that creates a server and list them:

from hcloud import Client
from hcloud.images import Image
from hcloud.server_types import ServerType

client = Client(token="{YOUR_API_TOKEN}")  # Please paste your API token here

# Create a server named my-server
response = client.servers.create(
    name="my-server",
    server_type=ServerType(name="cx22"),
    image=Image(name="ubuntu-22.04"),
)
server = response.server
print(f"{server.id=} {server.name=} {server.status=}")
print(f"root password: {response.root_password}")

# List your servers
servers = client.servers.get_all()
for server in servers:
    print(f"{server.id=} {server.name=} {server.status=}")

• To upgrade the package, please read the instructions available in the documentation.
• For more details on the API, please see the API reference.
• You can find some more examples under the examples/ directory.

Supported Python versions

We support python versions until end-of-life.

Experimental features

Experimental features are published as part of our regular releases (e.g. a product public beta). During an experimental phase, breaking changes on those features may occur within minor releases.

While experimental features will be announced in the release notes, you can also find whether a python class or function is experimental in its docstring:

Experimental:
    $PRODUCT is experimental, breaking changes may occur within minor releases.
    See https://docs.hetzner.cloud/changelog#$SLUG for more details.

Development

First, create a virtual environment and activate it:

make venv
source venv/bin/activate

You may setup pre-commit to run before you commit changes, this removes the need to run it manually afterwards:

pre-commit install

You can then run different tasks defined in the Makefile, below are the most important ones:

Build the documentation and open it in your browser:

make docs

Lint the code:

make lint

Run tests using the current python3 version:

make test

You may also run the tests for multiple python3 versions using tox:

tox .

Deprecations implementation

When deprecating a module or a function, you must:

• Update the docstring with a deprecated notice:

"""Get image by name

.. deprecated:: 1.19
    Use :func:`hcloud.images.client.ImagesClient.get_by_name_and_architecture` instead.
"""

• Raise a warning when the deprecated module or function is being used:

warnings.warn(
    "The 'hcloud.images.client.ImagesClient.get_by_name' method is deprecated, please use the "
    "'hcloud.images.client.ImagesClient.get_by_name_and_architecture' method instead.",
    DeprecationWarning,
    stacklevel=2,
)

Releasing experimental features

To publish experimental features as part of regular releases:

• an announcement, including a link to a changelog entry, must be added to the release notes.

• an Experimental notice, including a link to a changelog entry, must be added to the python classes and functions that are experimental:

  """
  Experimental:
      $PRODUCT is experimental, breaking changes may occur within minor releases.
      See https://docs.hetzner.cloud/changelog#$SLUG for more details.
  """
