FerretDB (previously MangoDB) was founded to become the de-facto open-source substitute to MongoDB. FerretDB is an open-source proxy, converting the MongoDB wire protocol queries to SQL - using PostgreSQL as a database engine.
Why do we need FerretDB?
MongoDB was originally an eye-opening technology for many of us developers, empowering us to build applications faster than using relational databases. In its early days, its ease-to-use and well-documented drivers made MongoDB one of the simplest database solutions available. However, as time passed, MongoDB abandoned its open-source roots; changing the license to SSPL - making it unusable for many open source and early stage commercial projects.
Most MongoDB users are not in need of many advanced features offered by MongoDB; however, they are in need of an easy to use open-source database solution. Recognizing this, FerretDB is here to fill that gap.
FerretDB will be compatible with MongoDB drivers and will strive to serve as a drop-in replacement for MongoDB.
What you see here is a tech demo - intended to show a proof of concept. Over the next couple of months we will be adding more. See this example for a short demonstration.
FerretDB is in its very early stages and welcomes all contributors. See our CONTRIBUTING.md.
These steps describe a quick local setup. They are not suitable for most production use-cases because they keep all data inside containers.
- Store the following in the
version: "3" services: postgres: image: postgres:14 container_name: postgres ports: - 5432:5432 environment: - POSTGRES_USER=user - POSTGRES_DB=ferretdb - POSTGRES_HOST_AUTH_METHOD=trust postgres_setup: image: postgres:14 container_name: postgres_setup restart: on-failure entrypoint: ["sh", "-c", "psql -h postgres -U user -d ferretdb -c 'CREATE SCHEMA IF NOT EXISTS test'"] ferretdb: image: ghcr.io/ferretdb/ferretdb:latest container_name: ferretdb restart: on-failure ports: - 27017:27017 command: ["-listen-addr=:27017", "-postgresql-url=postgres://[email protected]:5432/ferretdb"]
postgrescontainer runs PostgreSQL 14 that would store data.
postgres_setupcontainer creates a PostgreSQL schema
testthat would act like a FerretDB database of the same name.
Start services with
docker-compose up -d.
If you have
mongoshinstalled, just run it to connect to FerretDB database
test. If not, run the following command to run
mongoshinside the temporary MongoDB container, attaching to the same Docker network:
docker run --rm -it --network=ferretdb_default --entrypoint=mongosh mongo:5 mongodb://ferretdb/
