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.
$ docker run --name mongodb bitnami/mongodb:latest
$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-mongodb/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

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 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 Docker Image is to pull the prebuilt image from the Docker Hub Registry.
$ docker pull bitnami/mongodb: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:[TAG]
If you wish, you can also build the image yourself.
$ docker build -t bitnami/mongodb:latest https://github.com/bitnami/bitnami-docker-mongodb.git
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
path. If the mounted directory is empty, it will be initialized on the first run.
$ docker run \
-v /path/to/mongodb-persistence:/bitnami \
bitnami/mongodb:latest
or using Docker Compose:
version: '2'
services:
mongodb:
image: 'bitnami/mongodb:latest'
ports:
- "27017:27017"
volumes:
- /path/to/mongodb-persistence:/bitnami
Using Docker container networking, a MongoDB server running inside a container can easily be accessed by your application containers.
Containers attached to the same network can communicate with each other using the container name as the hostname.
In this example, we will create a MongoDB client instance that will connect to the server instance that is running on the same docker network as the client.
$ docker network create app-tier --driver bridge
Use the --network app-tier
argument to the docker run
command to attach the MongoDB container to the app-tier
network.
$ docker run -d --name mongodb-server \
--network app-tier \
bitnami/mongodb:latest
Finally we create a new container instance to launch the MongoDB client and connect to the server created in the previous step:
$ docker run -it --rm \
--network app-tier \
bitnami/mongodb:latest mongo --host mongodb-server
When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new bridge
network named app-tier
. In this example we assume that you want to connect to the MongoDB server from your own custom application image which is identified in the following snippet by the service name myapp
.
version: '2'
networks:
app-tier:
driver: bridge
services:
mongodb:
image: 'bitnami/mongodb:latest'
networks:
- app-tier
myapp:
image: 'YOUR_APPLICATION_IMAGE'
networks:
- app-tier
IMPORTANT:
- Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image
- In your application container, use the hostname
mongodb
to connect to the MongoDB server
Launch the containers using:
$ docker-compose up -d
When the container is executed for the first time, it will execute the files with extensions .sh
, and .js
located at /docker-entrypoint-initdb.d
.
In order to have your custom files inside the docker image you can mount them as a volume.
Passing extra command-line flags to the mongod service command is possible through the following env var:
MONGODB_EXTRA_FLAGS
: Flags to be appended to the startup command. No defaults
$ docker run --name mongodb -e ALLOW_EMPTY_PASSWORD=yes -e MONGODB_EXTRA_FLAGS='--wiredTigerCacheSizeGB=2' bitnami/mongodb:latest
or using Docker Compose:
version: '2'
services:
mongodb:
image: 'bitnami/mongodb:latest'
ports:
- "27017:27017"
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MONGODB_EXTRA_FLAGS=--wiredTigerCacheSizeGB=2
Enabling/disabling IPv6 is possible through the following env var:
MONGODB_ENABLE_IPV6
: Whether to enable/disable IPv6 on MongoDB. Default:yes
$ docker run --name mongodb -e ALLOW_EMPTY_PASSWORD=yes -e MONGODB_ENABLE_IPV6=yes bitnami/mongodb:latest
or using Docker Compose:
version: '2'
services:
mongodb:
image: 'bitnami/mongodb:latest'
ports:
- "27017:27017"
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MONGODB_ENABLE_IPV6=yes
Passing the MONGODB_ROOT_PASSWORD
environment variable when running the image for the first time will set the password of the root
user to the value of MONGODB_ROOT_PASSWORD
and enabled authentication on the MongoDB server.
$ docker run --name mongodb \
-e MONGODB_ROOT_PASSWORD=password123 bitnami/mongodb:latest
or using Docker Compose:
version: '2'
services:
mongodb:
image: 'bitnami/mongodb:latest'
ports:
- "27017:27017"
environment:
- MONGODB_ROOT_PASSWORD=password123
The root
user is configured to have full administrative access to the MongoDB server. When MONGODB_ROOT_PASSWORD
is not specified the server allows unauthenticated and unrestricted access.
You can create a user with restricted access to a database while starting the container for the first time. To do this, provide the MONGODB_USERNAME
, MONGO_PASSWORD
and MONGODB_DATABASE
environment variables.
$ docker run --name mongodb \
-e MONGODB_USERNAME=my_user -e MONGODB_PASSWORD=password123 \
-e MONGODB_DATABASE=my_database bitnami/mongodb:latest
or using Docker Compose:
version: '2'
services:
mongodb:
image: 'bitnami/mongodb:latest'
ports:
- "27017:27017"
environment:
- MONGODB_USERNAME=my_user
- MONGODB_PASSWORD=password123
- MONGODB_DATABASE=my_database
Note! Creation of a user enables authentication on the MongoDB server and as a result unauthenticated access by any user is not permitted.
A replication cluster can easily be setup with the Bitnami MongoDB Docker Image using the following environment variables:
MONGODB_REPLICA_SET_MODE
: The replication mode. Possible valuesprimary
/secondary
/arbiter
. No defaults.MONGODB_REPLICA_SET_NAME
: MongoDB replica set name. Default: replicasetMONGODB_PORT_NUMBER
: The port each MongoDB will use. Default: 27017MONGODB_PRIMARY_HOST
: MongoDB primary host. No defaults.MONGODB_PRIMARY_PORT_NUMBER
: MongoDB primary node port, as seen by other nodes. Default: 27017MONGODB_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.
Only for authentication:
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. No default.MONGODB_ROOT_PASSWORD
: MongoDB root password. No defaults. Only for primary node.MONGODB_PRIMARY_ROOT_PASSWORD
: MongoDB primary root password. No defaults. Only for secondaries and aribters nodes.
In a replication cluster you can have one primary node, zero or more secondary nodes and zero or one arbiter node.
Note: The total number of nodes on a replica set sceneraio cannot be higher than 8 (1 primary, 6 secondaries and 1 arbiter)
The first step is to start the MongoDB primary.
$ docker run --name mongodb-primary \
-e MONGODB_REPLICA_SET_MODE=primary \
bitnami/mongodb:latest
In the above command the container is configured as the primary
using the MONGODB_REPLICA_SET_MODE
parameter.
Next we start a MongoDB secondary container.
$ docker run --name mongodb-secondary \
--link mongodb-primary:primary \
-e MONGODB_REPLICA_SET_MODE=secondary \
-e MONGODB_PRIMARY_HOST=primary \
-e MONGODB_PRIMARY_PORT_NUMBER=27017 \
bitnami/mongodb:latest
In the above command the container is configured as a secondary
using the MONGODB_REPLICA_SET_MODE
parameter. The MONGODB_PRIMARY_HOST
and MONGODB_PRIMARY_PORT_NUMBER
parameters are used connect and with the MongoDB primary.
Finally we start a MongoDB arbiter container.
$ docker run --name mongodb-arbiter \
--link mongodb-primary:primary \
-e MONGODB_REPLICA_SET_MODE=arbiter \
-e MONGODB_PRIMARY_HOST=primary \
-e MONGODB_PRIMARY_PORT_NUMBER=27017 \
bitnami/mongodb:latest
In the above command the container is configured as a arbiter
using the MONGODB_REPLICA_SET_MODE
parameter. The MONGODB_PRIMARY_HOST
and MONGODB_PRIMARY_PORT_NUMBER
parameters are used connect and with the MongoDB primary.
You now have a three node MongoDB replication cluster up and running which can be scaled by adding/removing secondarys.
With Docker Compose the replicaset can be setup using:
version: '2'
services:
mongodb-primary:
image: 'bitnami/mongodb:latest'
environment:
- MONGODB_REPLICA_SET_MODE=primary
volumes:
- 'mongodb_master_data:/bitnami'
mongodb-secondary:
image: 'bitnami/mongodb:latest'
depends_on:
- mongodb-primary
environment:
- MONGODB_REPLICA_SET_MODE=secondary
- MONGODB_PRIMARY_HOST=mongodb-primary
- MONGODB_PRIMARY_PORT_NUMBER=27017
mongodb-arbiter:
image: 'bitnami/mongodb:latest'
depends_on:
- mongodb-primary
environment:
- MONGODB_REPLICA_SET_MODE=arbiter
- MONGODB_PRIMARY_HOST=mongodb-primary
- MONGODB_PRIMARY_PORT_NUMBER=27017
volumes:
mongodb_master_data:
driver: local
Or in case you want to set up the replicaset with authentication you can use the following file:
version: '2'
services:
mongodb-primary:
image: 'bitnami/mongodb:latest'
environment:
- MONGODB_REPLICA_SET_MODE=primary
- MONGODB_ROOT_PASSWORD=password123
- MONGODB_REPLICA_SET_KEY=replicasetkey123
volumes:
- 'mongodb_master_data:/bitnami'
mongodb-secondary:
image: 'bitnami/mongodb:latest'
depends_on:
- mongodb-primary
environment:
- MONGODB_REPLICA_SET_MODE=secondary
- MONGODB_PRIMARY_HOST=mongodb-primary
- MONGODB_PRIMARY_PORT_NUMBER=27017
- MONGODB_PRIMARY_ROOT_PASSWORD=password123
- MONGODB_REPLICA_SET_KEY=replicasetkey123
mongodb-arbiter:
image: 'bitnami/mongodb:latest'
depends_on:
- mongodb-primary
environment:
- MONGODB_REPLICA_SET_MODE=arbiter
- MONGODB_PRIMARY_HOST=mongodb-primary
- MONGODB_PRIMARY_PORT_NUMBER=27017
- MONGODB_PRIMARY_ROOT_PASSWORD=password123
- MONGODB_REPLICA_SET_KEY=replicasetkey123
volumes:
mongodb_master_data:
driver: local
Scale the number of secondary nodes using:
$ docker-compose up --detach --scale mongodb-primary=1 --scale mongodb-secondary=3 --scale mongodb-arbiter=1
The above command scales up the number of secondary nodes to 3
. You can scale down in the same way.
Note: You should not scale up/down the number of primary nodes. Always have only one primary node running.
There are three different roles in a replica set configuration (primary, secondary or arbiter). Each one of these roles are configured in a different way:
Primary node configuration:
The replica set is started with the rs.initiate()
command and some configuration options to force the primary to be the primary. Basically, the priority is increased from the default (1) to 5.
To verify the primary is actually the primary we validate it with the db.isMaster().ismaster
command.
The primary node has a volume attached so the data is preserved between deployments as long as the volume exists.
In addition, the primary node initialization script will check for the existence of a .initialized
file in the /bitnami/mongodb
folder to discern whether it should create a new replica set or on the contrary a replica set has already been initialized.
If the primary got killed and the volume is deleted, in order to start it again in the same replica set it is important to launch the container with the original IP so other members of the replica set already knows about it.
Secondary node configuration:
Once the primary node is up and running we can start adding secondary nodes (and arbiter). For that, the secondary node connects to the primary node and add itself as a secondary node with the command rs.add(SECONDARY_NODE_HOST)
.
After adding the secondary nodes we verified they have been successfully added by executing rs.status().members
to see if they appear in the list.
Arbiter node configuration:
Finally, the arbiters follows the same procedure than secondary nodes with the exception that the command to add it to the replica set is rs.addArb(ARBITER_NODE_HOST)
. An arbiter should be added when the sum of primary nodes plus secondaries nodes is even.
The image looks for configurations in /opt/bitnami/mongodb/conf/
. You can mount a volume at /opt/bitnami/mongodb/conf/
and copy/edit the configurations in the /path/to/mongodb-configuration-persistence/
. The default configurations will be populated to the conf/
directory if it's empty.
Run the MongoDB image, mounting a directory from your host.
$ docker run --name mongodb -v /path/to/mongodb-configuration-persistence:/opt/bitnami/mongodb/conf bitnami/mongodb:latest
or using Docker Compose:
version: '2'
services:
mongodb:
image: 'bitnami/mongodb:latest'
ports:
- "27017:27017"
volumes:
- /path/to/mongodb-configuration-persistence:/opt/bitnami/mongodb/conf
Edit the configuration on your host using your favorite editor.
$ vi /path/to/mongodb-configuration-persistence/mongodb.conf
After changing the configuration, restart your MongoDB container for changes to take effect.
$ docker restart mongodb
or using Docker Compose:
$ docker-compose restart mongodb
Refer to the configuration file options manual for the complete list of MongoDB configuration options.
The Bitnami MongoDB Docker image sends the container logs to the stdout
. To view the logs:
$ docker logs mongodb
or using Docker Compose:
$ docker-compose logs mongodb
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:latest
or if you're using Docker Compose, update the value of the image property to bitnami/mongodb:latest
.
Stop the currently running container using the command
$ docker stop mongodb
or using Docker Compose:
$ docker-compose stop mongodb
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
or using Docker Compose:
$ docker-compose rm -v mongodb
Re-create your container from the new image.
$ docker run --name mongodb bitnami/mongodb:latest
or using Docker Compose:
$ docker-compose up mongodb
- The MongoDB container has been migrated to a non-root user approach. Previously the container ran as the
root
user and the MongoDB daemon was started as themongo
user. From now on, both the container and the MongoDB daemon run as user1001
. As a consequence, the data directory must be writable by that user. You can revert this behavior by changingUSER 1001
toUSER root
in the Dockerfile.
MONGODB_USER
parameter has been renamed toMONGODB_USERNAME
.
- All volumes have been merged at
/bitnami/mongodb
. Now you only need to mount a single volume at/bitnami/mongodb
for persistence. - The logs are always sent to the
stdout
and are no longer collected in the volume.
