Learn how to connect to a Caching service with one of the world's most famous programming languages: Python.
Managed Databases (also called Cloud Databases) allow you to focus on building and deploying cloud applications while OVHcloud manages the database infrastructure and maintenance in operational conditions.
You can find an example in the GitHub examples repository.
Requirements
- access to the OVHcloud Control Panel
- a Public Cloud project in your OVHcloud account
- a Caching service running on your OVHcloud Cloud Databases (this guide can help you to meet this requirement)
- configure your Caching service to accept incoming connections
- a working Python environment
Concept
A Caching service can be managed in multiple ways. One of the easiest, yet powerful, is to use a Command Line Interface (CLI), as shown in our guide: Connect with CLI.
Another way is to interact directly using programming languages, such as Python.
We will need to set up our Python environment with the redis-py client, then code in Python to perform a few example actions.
Instructions
Set up your Python environment
To interact with your instance using Python, your development environment needs to be configured with:
- A compatible version of Python
- Redis-py
Please follow the official Redis-py to get the latest information.
Once your Python environment is set up and you begin executing a python --version in your command line interface (CLI), you should see information about the version as shown below:
laptop$ python3 --version Python 3.12.0
In the same console, by typing a pip list, check if redis-py is correctly installed:
laptop$ pip list Package Version ---------------------- ------- (...) redis 5.0.1 (...)
We are now ready to learn how to connect to our instance!
Connect with redis-py
In your Python environment, let's try a connection. To be sure that we are indeed connected, set a data pair and then check we can get the value of it.
redis-connect.py
import redis
r = redis.Redis.from_url( url='rediss://redisUser:6D74VEUdiLb3XMzE@redis-0d42e4a5-o2626ab53.database.cloud.ovh.us:20185')
r.set("foo","bar")
print(r.get("foo"))
$ python redis-connect.py $ b'bar'
