Using PyMongo with MongoDB Atlas¶
Atlas is MongoDB, Inc.’s hosted MongoDB as a
service offering. To connect to Atlas, pass the connection string provided by
Atlas to MongoClient:
client = pymongo.MongoClient(<Atlas connection string>)
Connections to Atlas require TLS/SSL.
Warning
Industry best practices recommend, and some regulations require, the use of TLS 1.1 or newer. Though no application changes are required for PyMongo to make use of the newest protocols, some operating systems or versions may not provide an OpenSSL version new enough to support them.
Users of macOS older than 10.13 (High Sierra) will need to install Python from python.org, homebrew, macports, or another similar source.
Users of Linux or other non-macOS Unix can check their OpenSSL version like this:
$ openssl version
If the version number is less than 1.0.1 support for TLS 1.1 or newer is not available. Contact your operating system vendor for a solution or upgrade to a newer distribution.
You can check your Python interpreter by installing the requests module and executing the following command:
python -c "import requests; print(requests.get('https://www.howsmyssl.com/a/check', verify=False).json()['tls_version'])"
You should see “TLS 1.X” where X is >= 1.
