Redis cache in Nextcloud

In this video I show you how to setup Redis as cache for Nextcloud. Using an in-memory cache such as Redis improves overall performance of your Nextcloud instance.

This particular way of setting up Redis is not typical: Redis is configured to be accessible through a socket instead of the default TCP/IP port. This socket is then shared through a Docker volume.
