Overview

FerretDB is an open source database that implements MongoDB compatibility on a PostgreSQL backend. Your existing MongoDB drivers, mongosh and the MongoDB query and aggregation language work unchanged while data is stored and queried in PostgreSQL.

Why the cloudimg image

cloudimg preinstalls FerretDB on a DocumentDB enabled PostgreSQL 17 backend, bound to loopback by default. A strong database password is generated uniquely on first boot with no default login, the PostgreSQL data directory sits on a dedicated resizable disk, and 24/7 support is included.

Common uses

  • MongoDB compatible workloads
  • Document storage on PostgreSQL
