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.

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