Outscale Python SDK (osc-sdk-python) is the official Python SDK to interact with the OUTSCALE API.

It allows you to:

• Configure multiple profiles through environment variables or credential files.
• Customize retry and rate-limit behavior.
• Enable detailed logging of requests and responses.

You will need an Outscale account and API credentials. If you do not have one yet, please visit the Outscale website.

• Python 3.10+
• pip (Python package manager)
• Access to the OUTSCALE API (valid access key / secret key or basic auth)
• Network access to the Outscale API endpoints

Install the pre-built Python package:

pip install osc-sdk-python

Clone the repository and build the package:

git clone https://github.com/outscale/osc-sdk-python.git
cd osc-sdk-python
make package

Then install the built wheel:

pip install dist/osc_sdk_python-0.43.0-py3-none-any.whl

When you use the SDK, you can choose a profile. Profiles can be defined via environment variables or in a credentials file. Environment variables take precedence over files.

In the credentials file, you can set a default profile named default. It will be used if you do not explicitly specify a profile.

The SDK understands the following environment variables:

export OSC_PROFILE=<PROFILE>            # default: "default"

# or explicit credentials:
export OSC_ACCESS_KEY=<ACCESS_KEY>
export OSC_SECRET_KEY=<SECRET_KEY>

# optional:
export OSC_REGION=<REGION>              # default: eu-west-2
export OSC_MAX_RETRIES=<INT>            # default: 3
export OSC_RETRY_BACKOFF_FACTOR=<FLOAT> # default: 1.0
export OSC_RETRY_BACKOFF_JITTER=<FLOAT> # default: 3.0
export OSC_RETRY_BACKOFF_MAX=<FLOAT>    # default: 30

By default, the SDK looks for a JSON configuration file at ~/.osc/config.json.

Example:

{
  "default": {
    "access_key": "<ACCESS_KEY>",
    "secret_key": "<SECRET_KEY>",
    "region": "<REGION>"
  },
  "profile_1": {
    "access_key": "<ACCESS_KEY>",
    "secret_key": "<SECRET_KEY>",
    "region": "<REGION>"
  },
  "profile_2": {
    "access_key": "<ACCESS_KEY>",
    "secret_key": "<SECRET_KEY>",
    "region": "<REGION>"
  }
}

Notes:

• Environment variables have priority over credentials files.

You can also use osc-sdk-python with basic authentication using your account email and password. Note that some API calls may be blocked with this method. See the authentication documentation for more details.

Example:

from osc_sdk_python import Gateway

with Gateway(email="[email protected]", password="yourAccountPassword") as gw:
    keys = gw.ReadAccessKeys()

The following options can be provided when initializing the Gateway to customize the retry behavior of the SDK:

• max_retries (integer, default 3)
• retry_backoff_factor (float, default 1.0)
• retry_backoff_jitter (float, default 3.0)
• retry_backoff_max (float, default 30)

These options follow the same behavior as their counterparts in urllib3.util.Retry, but are implemented by the SDK retry logic.

Example:

from osc_sdk_python import Gateway

gw = Gateway(
    max_retries=5,
    retry_backoff_factor=0.5,
    retry_backoff_jitter=1.0,
    retry_backoff_max=120,
)

You can also configure rate limiting when initializing the Gateway:

• limiter_max_requests (integer, default 5)
• limiter_window (integer, default 1)

Example:

from osc_sdk_python import Gateway

gw = Gateway(
    limiter_max_requests=20,
    limiter_window=5,
)

More usage patterns and logging examples are documented in:

• docs/examples.md

Some example topics covered in docs/examples.md:

• Listing VMs and volumes
• Using profiles and regions
• Raw calls with gw.raw("ActionName", **params)
• Enabling and reading logs

Common issues (such as UTF-8 / locale errors when reading the API spec) and their workarounds are documented in:

• docs/troubleshooting.md
