unistra_s3() → None[source]#

Initialize a temporary S3 environment as a context manager, with Unistra endpoint

This function searches for S3 configuration in many places. It does apply configuration variables precedence, and you might have a use for it. Here is the order of precedence from least to greatest (the last listed configuration variables override all other variables):

  1. AWS profile “unistra”

  2. AWS environment variable

Profile unistra is first read from X:/SI/Secrets/config and X:/SI/Secrets/credentials. If this file does not exist, it fallbacks to local file $USER/.aws/config and $USER/.aws/credentials.

You can use ready-to-use environements provided by the Sertit or asks for s3 credentials.

Parameters:

default_endpoint (str) – Default Endpoint to look for

Example

>>> from sertit.unistra import unistra_s3
>>> from sertit import AnyPath
>>> def file_exists(path: str):
>>>     with unistra_s3():
>>>         pth = AnyPath(path)
>>>         print(pth.exists())
>>> file_exists("s3://sertit-geodatastore/GLOBAL/COPDEM_30m/COPDEM_30m.vrt")
True
