GCP: connect to Memotystore from cloud run Django app?

Question

I'd like to add cache to my Django app hosting on Cloud Run.

From Django official docs, we can connect Django to a memory-based cache. Since I'm using Cloud Run, the memory get cleaned.

Memotystore seems good for this purpose, but there's only tutorial for flask and redis.

How could I achieve this?

Or should I just use a database caching?

Answer 1

• Connect Redis instance to Cloud Run service using the steps in documentation.
• To connect from Cloud Run (fully managed) to Memorystore you need to use the mechanism called "Serverless VPC Access" or a "VPC Connector"
  
• First, you have to create a Serverless VPC Access Connector and then configure Cloud Run to use this connector
• See connecting to a VPC Network for more information.

Alternatives to using this include:

• Use Cloud Run for Anthos, where GKE provides the capability to connect to Memorystore if the cluster is configured for it.
• Stay within fully managed Serverless but use a GA version of the Serverless VPC Access feature by using App Engine with Memorystore.
• See this answer to connect to Memorystore from Cloud Run using an SSH tunnel via GCE.
