MongoDB® Sharded packaged by Bitnami

What is MongoDB® Sharded?

MongoDB® is an open source NoSQL database that uses JSON for data storage. MongoDB™ Sharded improves scalability and reliability for large datasets by distributing data across multiple machines.

Overview of MongoDB® Sharded Disclaimer: The respective trademarks mentioned in the offering are owned by the respective companies. We do not provide a commercial license for any of these products. This listing has an open-source license. MongoDB(R) is run and maintained by MongoDB, which is a completely separate project from Bitnami.

⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new Bitnami Secure Images initiative. As part of this transition:

  • Granting community users access for the first time to security-optimized versions of popular container images.
  • Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
  • Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
  • For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the Bitnami Secure Images announcement.

Why use Bitnami Secure Images?

  • Bitnami Secure Images and Helm charts are built to make open source more secure and enterprise ready.
  • Triage security vulnerabilities faster, with transparency into CVE risks using industry standard Vulnerability Exploitability Exchange (VEX), KEV, and EPSS scores.
  • Our hardened images use a minimal OS (Photon Linux), which reduces the attack surface while maintaining extensibility through the use of an industry standard package format.
  • Stay more secure and compliant with continuously built images updated within hours of upstream patches.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • Hardened images come with attestation signatures (Notation), SBOMs, virus scan reports and other metadata produced in an SLSA-3 compliant software factory.

Only a subset of BSI applications are available for free. Looking to access the entire catalog of applications as well as enterprise support? Try the commercial edition of Bitnami Secure Images today.

How to deploy MongoDB® Sharded in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami MongoDB® Sharded Chart GitHub repository.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Subscribe to project updates by watching the bitnami/containers GitHub repo.

Get this image

The recommended way to get the Bitnami MongoDB® Sharded Docker Image is to pull the prebuilt image from the Docker Hub Registry.

docker pull bitnami/mongodb-sharded:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

docker pull bitnami/mongodb-sharded:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Persisting your database

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should create a directory and mount it at the /bitnami/mongodb path. If the mounted directory is empty, it will be initialized on the first run. As this is a non-root container, directory must have read/write permissions for the UID 1001.

docker run \
    -v /path/to/mongodb-persistence:/bitnami/mongodb \
    bitnami/mongodb-sharded:latest

or by modifying the docker-compose.yml file present in this repository:

  • Create directories to hold the persistence data. At minimum you will need one directory for each mongo instance running in the sharded cluster. For example, that means one directory for mongos, mongocfg and mongoshard. You need to assign read write permission to UID 1001 (ie. mkdir [directory] && chown 1001:1001 [directory] && chmod 777 [directory]) to all directories.

Setting up a sharded cluster

In a sharded cluster, there are three components:

  • Mongos: Interface between the applications and the sharded database.
  • Config Servers: Stores metadata and configuration settings for the sharded database.
  • Shards: Contains a subset of the data.

A sharded cluster can easily be setup with the Bitnami MongoDB® Sharded Docker Image using the following environment variables:

  • MONGODB_SHARDING_MODE: The sharding mode. Possible values: mongos/configsvr/shardsvr. No defaults.
  • MONGODB_REPLICA_SET_NAME: MongoDB® replica set name. In a sharded cluster we will have multiple replica sets. Default: replicaset
  • MONGODB_MONGOS_HOST: MongoDB® mongos instance host. No defaults.
  • MONGODB_CFG_REPLICA_SET_NAME: MongoDB® config server replica set name. In a sharded cluster we will have multiple replica sets. Default: replicaset
  • MONGODB_CFG_PRIMARY_HOST: MongoDB® config server primary host. No defaults.
  • MONGODB_ADVERTISED_HOSTNAME: MongoDB® advertised hostname. No defaults. It is recommended to pass this environment variable if you experience issues with ephemeral IPs. Setting this env var makes the nodes of the replica set to be configured with a hostname instead of the machine IP.
  • MONGODB_REPLICA_SET_KEY: MongoDB® replica set key. Length should be greater than 5 characters and should not contain any special characters. Required for all nodes in the sharded cluster. No default.
  • MONGODB_ROOT_PASSWORD: MongoDB® root password. No defaults.
  • MONGODB_REPLICA_SET_MODE: The replication mode. Possible values primary/secondary/arbiter. No defaults.

Step 1: Create the config server replica set

The first step is to start the MongoDB® primary config server.

docker run --name mongodb-configsvr-primary \
  -e MONGODB_SHARDING_MODE=configsvr \
  -e MONGODB_REPLICA_SET_MODE=primary \
  -e MONGODB_ROOT_PASSWORD=password123 \
  -e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
  -e MONGODB_REPLICA_SET_NAME=config-replicaset \
   bitnami/mongodb-sharded:latest

In the above command the container is configured as Config server using the MONGODB_SHARDING_MODE parameter and as primary using the MONGODB_REPLICA_SET_MODE parameter. You can configure secondary nodes by following the Bitnami MongoDB® container replication guide.

Step 2: Create the mongos instance

Next we start a MongoDB® mongos server and connect it to the config server replica set.

docker run --name mongos \
  --link mongodb-configsvr-primary:cfg-primary \
  -e MONGODB_SHARDING_MODE=mongos \
  -e MONGODB_CFG_PRIMARY_HOST=cfg-primary \
  -e MONGODB_CFG_REPLICA_SET_NAME=config-replicaset \
  -e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
  -e MONGODB_ROOT_PASSWORD=password123 \
  bitnami/mongodb-sharded:latest

In the above command the container is configured as a mongos using the MONGODB_SHARDING_MODE parameter. The MONGODB_CFG_PRIMARY_HOST, MONGODB_REPLICA_SET_KEY, MONGODB_CFG_REPLICA_SET_NAME and MONGODB_ROOT_PASSWORD parameters are used connect and with the MongoDB® primary config server.

Step 3: Create a shard

Finally we start a MongoDB® data shard container.

docker run --name mongodb-shard0-primary \
  --link mongodb-configsvr-primary:cfg-primary \
  --link mongos:mongos \
  -e MONGODB_SHARDING_MODE=shardsvr \
  -e MONGODB_MONGOS_HOST=mongos \
  -e MONGODB_ROOT_PASSWORD=password123 \
  -e MONGODB_REPLICA_SET_MODE=primary \
  -e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
  -e MONGODB_REPLICA_SET_NAME=shard0 \
  bitnami/mongodb-sharded:latest

In the above command the container is configured as a data shard using the MONGODB_SHARDING_MODE parameter. The MONGODB_MONGOS_HOST, MONGODB_ROOT_PASSWORD and MONGODB_REPLICA_SET_KEY parameters are used connect and with the Mongos instance. You can configure secondary nodes by following the Bitnami MongoDB® container replication guide.

You now have a sharded MongoDB® cluster up and running. You can add more shards by repeating step 3. Make sure you set a different MONGODB_REPLICA_SET_NAME value. You can also add more mongos instances by repeating step 2.

With Docker Compose the sharded cluster can be setup using:

version: '2'

services:
  mongos:
    image: bitnami/mongodb-sharded:latest
    environment:
      - MONGODB_SHARDING_MODE=mongos
      - MONGODB_CFG_PRIMARY_HOST=mongodb-cfg
      - MONGODB_CFG_REPLICA_SET_NAME=cfgreplicaset
      - MONGODB_REPLICA_SET_KEY=replicasetkey123
      - MONGODB_ROOT_PASSWORD=password123
    ports:
      - 27017:27017

  mongodb-shard0-primary:
    image: bitnami/mongodb-sharded:latest
    environment:
      - MONGODB_SHARDING_MODE=shardsvr
      - MONGODB_MONGOS_HOST=mongos
      - MONGODB_ROOT_PASSWORD=password123
      - MONGODB_REPLICA_SET_MODE=primary
      - MONGODB_REPLICA_SET_KEY=replicasetkey123
      - MONGODB_REPLICA_SET_NAME=shard0
    volumes:
      - shard0_data:/bitnami

  mongodb-configsvr-primary:
    image: bitnami/mongodb-sharded:latest
    environment:
      - MONGODB_SHARDING_MODE=configsvr
      - MONGODB_ROOT_PASSWORD=password123
      - MONGODB_REPLICA_SET_MODE=primary
      - MONGODB_REPLICA_SET_KEY=replicasetkey123
      - MONGODB_REPLICA_SET_NAME=config-replicaset
    volumes:
      - cfg_data:/bitnami

volumes:

More MongoDB® configuration settings

The Bitnami MongoDB® Sharded image contains the same configuration features than the Bitnami MongoDB® image.

FIPS configuration in Bitnami Secure Images

The Bitnami MongoDB® Sharded Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

  • OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Logging

The Bitnami MongoDB® Sharded Docker image sends the container logs to the stdout. To view the logs:

docker logs mongodb-sharded

or using Docker Compose:

docker-compose logs mongodb-sharded

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Maintenance

Upgrade this image

Bitnami provides up-to-date versions of MongoDB®, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.

Step 1: Get the updated image

docker pull bitnami/mongodb-sharded:latest

or if you're using Docker Compose, update the value of the image property to bitnami/mongodb-sharded:latest.

Step 2: Stop and backup the currently running container

Stop the currently running container using the command

docker stop mongodb-sharded

or using Docker Compose:
