MongoDB is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster.
This container flavor uses the sharding method for distributing data across multiple machines. This is meant for deployments with very large data sets and high throughput operations.
All MongoDB versions released after October 16, 2018 (3.6.9 or later, 4.0.4 or later or 4.1.5 or later) are licensed under the Server Side Public License that is not currently accepted as a Open Source license by the Open Source Iniciative (OSI).

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.
Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.
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.
NOTE: Debian 8 images have been deprecated in favor of Debian 9 images. Bitnami will not longer publish new Docker images based on Debian 8.

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.
$ docker build -t bitnami/mongodb-sharded:latest 'https://github.com/bitnami/bitnami-docker-mongodb-sharded.git#master:4.0/debian-9'
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 mount a directory at the /bitnami/mongodb
path. If the mounted directory is empty, it will be initialized on the first run.
$ 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:
services:
mongodb-sharded:
...
volumes:
- /path/to/mongodb-persistence:/bitnami
...
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: replicasetMONGODB_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: replicasetMONGODB_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 valuesprimary
/secondary
/arbiter
. No defaults.
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.
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.
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:
shard0_data:

The Bitnami MongoDB Sharded image contains the same configuration features than the Bitnami MongoDB image.
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.
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.
$ 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
.
Stop the currently running container using the command
$ docker stop mongodb-sharded
or using Docker Compose:
$ docker-compose stop mongodb-sharded
Next, take a snapshot of the persistent volume /path/to/mongodb-persistence
using:
$ rsync -a /path/to/mongodb-persistence /path/to/mongodb-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
You can use this snapshot to restore the database state should the upgrade fail.
$ docker rm -v mongodb-sharded
or using Docker Compose:
$ docker-compose rm -v mongodb-sharded
Re-create your container from the new image.
$ docker run --name mongodb bitnami/mongodb-sharded:latest
or using Docker Compose:
$ docker-compose up mongodb-sharded
We'd love for you to contribute to this container. You can request new features by creating an issue, or submit a pull request with your contribution.
If you encountered a problem running this container, you can file an issue. For us to provide better support, be sure to include the following information in your issue:
