With the upcoming end-of-life (EOL) of MSR 3.1.x, Mirantis encourages you to upgrade to the latest supported version to ensure continued support and security updates.

Configure external storage

By default, MSR uses the local filesystem of the node on which it is running to store your Docker images. As an alternative, you can configure MSR to use an external storage backend for improved performance or high availability.

• Configure MSR image storage
• Deploy MSR on NFS
• Configure MSR for a cloud storage provider (S3)
• Switch storage backends
