Install a Highly Available Cache#
Mirantis Secure Registry (MSR) uses an external cache backend to store the following non-persistent operational data:
- User sessions to maintain state for active authenticated UI sessions.
- Jobservice queues to coordinate background operations, including image replication, vulnerability scanning, and garbage collection.
MSR supports Valkey (recommended) and Redis as cache backends. Select an installation section based on your requirements.

-
Redis with Replication
For development and staging environments.
-
Redis with Sentinel
