MongoDB Testing Setups

This directory provides minimal Docker Compose setups to run MongoDB locally for testing.

Available setups:

Prerequisites

These setups use Docker images like ${MONGO_IMAGE:-mongo}:${MONGO_VERSION:-7.0}. If you don’t set MONGO_VERSION, it defaults to 7.0.

To run a specific MongoDB version, prefix your compose command with the variable (examples for zsh):

bash

# Use MongoDB 5.0
MONGO_VERSION=5.0 docker-compose up -d

# Or with Docker Compose V2 syntax
MONGO_VERSION=7.0 docker compose up -d

You can also override the image name if needed:

bash

MONGO_IMAGE=mongo MONGO_VERSION=7.0 docker-compose up -d

Run each from its own subdirectory.

bash

cd standalone
docker-compose up -d
./seed-standalone.sh

bash

cd replica_set
docker-compose up -d
./init-replica-set.sh

bash

cd sharded
docker-compose up -d
./init-sharded-cluster.sh
./verify-sharding.sh

From within a subdirectory:

bash

docker-compose down -v

These environments are for local testing only.
