In order to unify the approaches followed for Bitnami containers and Bitnami Helm charts, we are moving the different bitnami/bitnami-docker-<container>
repositories to a single monorepo bitnami/containers
. Please follow bitnami/containers to keep you updated about the latest Bitnami images.

MongoDB® packaged by Bitnami
What is MongoDB®?
MongoDB® is a relational open source NoSQL database. Easy to use, it stores data in JSON-like documents. Automated scalability and high-performance. Ideal for developing cloud native applications.
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.
TL;DR
$ docker run --name mongodb bitnami/mongodb:latest
Docker Compose
$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-mongodb/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d
Why use Bitnami Images?
- Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
- With Bitnami images the latest bug fixes and features are available as soon as possible.
- 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.
- All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
- All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use
DOCKER_CONTENT_TRUST=1
to verify the integrity of the images. - Bitnami container images are released on a regular basis with the latest distribution packages available.
How to deploy MongoDB® 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® Chart GitHub repository.
Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.
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.

Get this image
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#master:5.0/debian-11'
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 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:latest
or by modifying the docker-compose.yml
file present in this repository:
...
services:
mongodb:
...
volumes:
- - 'mongodb_data:/bitnami/mongodb'
+ - /path/to/mongodb-persistence:/bitnami/mongodb
...
NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID
1001
.
Connecting to other containers
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.
Using the Command Line
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.
Step 1: Create a network
$ docker network create app-tier --driver bridge
Step 2: Launch the MongoDB® server instance
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
Step 3: Launch your MongoDB® client instance
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
Using Docker Compose
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
Configuration
Initializing a new instance
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.

Configuring the system log verbosity level is possible through the following env vars:
MONGODB_DISABLE_SYSTEM_LOG
: Whether to enable/disable system log on MongoDB®. Default:false
. Possible values:[true, false]
.MONGODB_SYSTEM_LOG_VERBOSITY
: MongoDB® system log verbosity level. Default:0
. Possible values:[0, 1, 2, 3, 4, 5]
. For more information about the verbosity levels please refer to the MongoDB® documentation
$ docker run --name mongodb -e ALLOW_EMPTY_PASSWORD=yes -e MONGODB_SYSTEM_LOG_VERBOSITY='3' bitnami/mongodb:latest
or by modifying the docker-compose.yml
file present in this repository:
services:
mongodb:
...
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MONGODB_SYSTEM_LOG_VERBOSITY=3
...
Using numactl
In order to enable launching commands using numactl, set the MONGODB_ENABLE_NUMACTL
variable to true. For more information on this, check the official [MongoDB documentation][(https://docs.mongodb.com/manual/administration/production-notes/#configuring-numa-on-linux)
Enabling/disabling IPv6
Enabling/disabling IPv6 is possible through the following env var:
MONGODB_ENABLE_IPV6
: Whether to enable/disable IPv6 on MongoDB®. Default:false
. Possible values:[true, false]
To enable IPv6 support, you can execute:
$ docker run --name mongodb -e ALLOW_EMPTY_PASSWORD=yes -e MONGODB_ENABLE_IPV6=yes bitnami/mongodb:latest
or by modifying the docker-compose.yml
file present in this repository:
services:
mongodb:
...
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MONGODB_ENABLE_IPV6=yes
...
Enabling/disabling directoryPerDB
Enabling/disabling directoryPerDB is possible through the following env var:
MONGODB_ENABLE_DIRECTORY_PER_DB
: Whether to enable/disable directoryPerDB on MongoDB®. Default:true
. Possible values:[true, false]
$ docker run --name mongodb -e ALLOW_EMPTY_PASSWORD=yes -e MONGODB_ENABLE_DIRECTORY_PER_DB=yes bitnami/mongodb:latest
or by modifying the docker-compose.yml
file present in this repository:
services:
mongodb:
...
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MONGODB_ENABLE_DIRECTORY_PER_DB=yes
...
Enabling/disabling journaling
Enabling/disabling journal is possible through the following env var:
MONGODB_ENABLE_JOURNAL
: Whether to enable/disable journaling on MongoDB®. Default:true
. Possible values:[true, false]
$ docker run --name mongodb -e ALLOW_EMPTY_PASSWORD=yes -e MONGODB_ENABLE_JOURNAL=true bitnami/mongodb:latest
or by modifying the docker-compose.yml
file present in this repository:
services:
mongodb:
...
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MONGODB_ENABLE_JOURNAL=true
...
Setting the root user and password on first run
Passing the MONGODB_ROOT_PASSWORD
environment variable when running the image for the first time will set the password of MONGODB_ROOT_USER
to the value of MONGODB_ROOT_PASSWORD
and enable authentication on the MongoDB® server. If unset, MONGODB_ROOT_USER
defaults to root
.
$ docker run --name mongodb \
-e MONGODB_ROOT_PASSWORD=password123 bitnami/mongodb:latest
or by modifying the docker-compose.yml
file present in this repository:
services:
mongodb:
...
environment:
- MONGODB_ROOT_PASSWORD=password123
...
The MONGODB_ROOT_USER
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.
Creating a user and database on first run
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
, MONGODB_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 by modifying the docker-compose.yml
file present in this repository:
services:
mongodb:
...
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.
Setting up replication
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_INITIAL_PRIMARY_HOST
: MongoDB® initial primary host, once the replicaset is created any node can be eventually promoted to be the primary. No defaults.MONGODB_INITIAL_PRIMARY_PORT_NUMBER
: MongoDB® initial 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.MONGODB_ADVERTISE_IP
: MongoDB® advertised hostname is set to container ip. Default: false. OverridesMONGODB_ADVERTISED_HOSTNAME
MONGODB_ADVERTISED_PORT_NUMBER
: MongoDB® advertised port number. No defaults. It is recommended to pass this environment variable if you have a proxy port forwarding requests to container.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_USER
: MongoDB® root user name. Default: root.MONGODB_ROOT_PASSWORD
: MongoDB® root password. No defaults. Only for primary node.MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD
: MongoDB® initial primary root password. No defaults. Only for secondaries and arbiter 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 scenario cannot be higher than 8 (1 primary, 6 secondaries and 1 arbiter)
Step 1: Create the replication primary
The first step is to start the MongoDB® primary.
$ docker run --name mongodb-primary \
-e MONGODB_REPLICA_SET_MODE=primary \
-e MONGODB_ADVERTISED_HOSTNAME=mongodb-primary \
-e MONGODB_ROOT_PASSWORD=password123 \
-e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
bitnami/mongodb:latest
In the above command the container is configured as the primary
using the MONGODB_REPLICA_SET_MODE
parameter.
Step 2: Create the replication secondary node
Next we start a MongoDB® secondary container.
$ docker run --name mongodb-secondary \
--link mongodb-primary:primary \
-e MONGODB_REPLICA_SET_MODE=secondary \
-e MONGODB_ADVERTISED_HOSTNAME=mongodb-secondary \
-e MONGODB_INITIAL_PRIMARY_HOST=mongodb-primary \
-e MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017 \
-e MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD=password123 \
-e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
bitnami/mongodb:latest
In the above command the container is configured as a secondary
using the MONGODB_REPLICA_SET_MODE
parameter. The MONGODB_INITIAL_PRIMARY_HOST
and MONGODB_INITIAL_PRIMARY_PORT_NUMBER
parameters are used connect and with the MongoDB® primary.
Step 3: Create a replication arbiter node
Finally we start a MongoDB® arbiter container.
$ docker run --name mongodb-arbiter \
--link mongodb-primary:primary \
-e MONGODB_REPLICA_SET_MODE=arbiter \
-e MONGODB_ADVERTISED_HOSTNAME=mongodb-arbiter \
-e MONGODB_INITIAL_PRIMARY_HOST=mongodb-primary \
-e MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017 \
-e MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD=password123 \
-e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
bitnami/mongodb:latest
In the above command the container is configured as a arbiter
using the MONGODB_REPLICA_SET_MODE
parameter. The MONGODB_INITIAL_PRIMARY_HOST
and MONGODB_INITIAL_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 secondaries.
Optional: Create a replication hidden node
If we want a replication hidden node, we start a MongoDB® hidden container.
$ docker run --name mongodb-hidden \
--link mongodb-primary:primary \
-e MONGODB_REPLICA_SET_MODE=hidden \
-e MONGODB_ADVERTISED_HOSTNAME=mongodb-hidden \
-e MONGODB_INITIAL_PRIMARY_HOST=mongodb-primary \
-e MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017 \
-e MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD=password123 \
-e MONGODB_REPLICA_SET_KEY=replicasetkey123 \
bitnami/mongodb:latest
In the above command the container is configured as a hidden
using the MONGODB_REPLICA_SET_MODE
parameter. The MONGODB_INITIAL_PRIMARY_HOST
and MONGODB_INITIAL_PRIMARY_PORT_NUMBER
parameters are used connect and with the MongoDB® primary.
With Docker Compose the replicaset can be setup using:
version: '2'
services:
mongodb-primary:
image: 'bitnami/mongodb:latest'
environment:
- MONGODB_ADVERTISED_HOSTNAME=mongodb-primary
- 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_ADVERTISED_HOSTNAME=mongodb-secondary
- MONGODB_REPLICA_SET_MODE=secondary
- MONGODB_INITIAL_PRIMARY_HOST=mongodb-primary
- MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017
- MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD=password123
- MONGODB_REPLICA_SET_KEY=replicasetkey123
mongodb-arbiter:
image: 'bitnami/mongodb:latest'
depends_on:
- mongodb-primary
environment:
- MONGODB_ADVERTISED_HOSTNAME=mongodb-arbiter
- MONGODB_REPLICA_SET_MODE=arbiter
- MONGODB_INITIAL_PRIMARY_HOST=mongodb-primary
- MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017
- MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD=password123
- MONGODB_REPLICA_SET_KEY=replicasetkey123
volumes:
mongodb_master_data:
driver: local
and run docker-compose using:
$ docker-compose up --detach
In the case you want to scale the number of secondary nodes using the docker-compose parameter --scale
, the MONGODB_ADVERTISED_HOSTNAME must not be set in mongodb-secondary and mongodb-arbiter defintions.
version: '2'
services:
mongodb-primary:
image: 'bitnami/mongodb:latest'
environment:
- MONGODB_ADVERTISED_HOSTNAME=mongodb-primary
- 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_INITIAL_PRIMARY_HOST=mongodb-primary
- MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017
- MONGODB_INITIAL_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_INITIAL_PRIMARY_HOST=mongodb-primary
- MONGODB_INITIAL_PRIMARY_PORT_NUMBER=27017
- MONGODB_INITIAL_PRIMARY_ROOT_PASSWORD=password123
- MONGODB_REPLICA_SET_KEY=replicasetkey123
volumes:
mongodb_master_data:
driver: local
And then run docker-compose 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. Note: In this case, the client has to be in the same docker network to be able to reach all the nodes.
How is a replica set configured?
There are four different roles in a replica set configuration (primary, secondary, hidden 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:
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.
Hidden node configuration:
Finally, the hidden node follows the same procedure than secondary nodes with the exception that the command to add it to the replica set is rs.add(host: HIDDEN_NODE_HOST, hidden: true, priority: 0})
.
Enabling SSL/TLS
This container supports enabling SSL/TLS between nodes in the cluster, as well as between mongo clients and nodes, by setting the MONGODB_EXTRA_FLAGS
and MONGODB_CLIENT_EXTRA_FLAGS
environment variables,
together with the correct MONGODB_ADVERTISED_HOSTNAME
.
Before starting the cluster you need to generate PEM certificates as required by Mongo - one way is to create self-signed certificates using openssl
(see http://www.openssl.org).
The certificates generated as described are not for production use
Another option would be to use letsencrypt certificates; the required configuration steps for that scenario are left as an exercise for the user and are beyond the scope of this README.
Generating self-signed certificates
- Generate a new private key which will be used to create your own Certificate Authority (CA):
openssl genrsa -out mongoCA.key 2048
- Create the public certificate for your own CA:
openssl req -x509 -new \
-subj "/C=US/ST=NY/L=New York/O=Example Corp/OU=IT Department/CN=mongoCA" \
-key mongoCA.key -out mongoCA.crt
- Create a Certificate Signing Request for a node
${NODE_NAME}
, the essential part here is that theCommon Name
corresponds to the hostname by which the nodes will be addressed. Example formongodb-primary
:
export NODE_NAME=mongodb-primary
openssl req -new -nodes \
-subj "/C=US/ST=NY/L=New York/O=Example Corp/OU=IT Department/CN=${NODE_NAME}" \
-keyout ${NODE_NAME}.key -out ${NODE_NAME}.csr
- Create a certificate from the Certificate Signing Request and sign it using the private key of your previously created Certificate Authority:
openssl x509 \
-req -days 365 -in ${NODE_NAME}.csr -out ${NODE_NAME}.crt \
-CA mongoCA.crt -CAkey mongoCA.key -CAcreateserial -extensions req
- Create a PEM bundle using the private key and the public certificate:
cat ${NODE_NAME}.key ${NODE_NAME}.crt > ${NODE_NAME}.pem
NB: Afterwards you do not need the Certificate Signing Request.
rm ${NODE_NAME}.csr
Repeat the process to generate PEM bundles for all the nodes in your cluster.
Starting the cluster
After having generated the certificates and making them available to the containers at the correct mount points (i.e. /certificates/
), the environment variables could be setup as in the following examples.
Example settings for the primary node mongodb-primary
:
MONGODB_ADVERTISED_HOSTNAME=mongodb-primary
MONGODB_EXTRA_FLAGS=--tlsMode=requireTLS --tlsCertificateKeyFile=/certificates/mongodb-primary.pem --tlsClusterFile=/certificates/mongodb-primary.pem --tlsCAFile=/certificates/mongoCA.crt
MONGODB_CLIENT_EXTRA_FLAGS=--tls --tlsCertificateKeyFile=/certificates/mongodb-primary.pem --tlsCAFile=/certificates/mongoCA.crt
Example corresponding settings for a secondary node mongodb-secondary
:
MONGODB_ADVERTISED_HOSTNAME=mongodb-secondary
MONGODB_EXTRA_FLAGS=--tlsMode=requireTLS --tlsCertificateKeyFile=/certificates/mongodb-secondary.pem --tlsClusterFile=/certificates/mongodb-secondary.pem --tlsCAFile=/certificates/mongoCA.crt
MONGODB_CLIENT_EXTRA_FLAGS=--tls --tlsCertificateKeyFile=/certificates/mongodb-secondary.pem --tlsCAFile=/certificates/mongoCA.crt
Connecting to the mongo daemon via SSL
After successfully starting a cluster as specified, within the container it should be possible to connect to the mongo daemon on the primary node using:
/opt/bitnami/mongodb/bin/mongo -u ${MONGODB_ROOT_USER} -p ${MONGODB_ROOT_PASSWORD} --host mongodb-primary --tls --tlsCertificateKeyFile=/certificates/mongodb-primary.pem --tlsCAFile=/certificates/mongoCA.crt
NB: We only support --clusterAuthMode=keyFile
in this configuration.

- For more extensive information regarding related configuration options: https://docs.mongodb.com/manual/reference/program/mongod/#tls-ssl-options, Especially client authentication and requirements for common name and OU/DN/etc. fields in the certificates are important for creating a secure setup.
Configuration file
The image looks for mounted configurations files in /bitnami/mongodb/conf/
. You can mount a volume at /bitnami/mongodb/conf/
and copy/edit the configurations in the /path/to/mongodb-configuration-persistence/
. The default configurations will be populated to the /opt/bitnami/mongodb/conf/
directory if it's empty.
Step 1: Run the MongoDB® image
Run the MongoDB® image, mounting a directory from your host.
$ docker run --name mongodb -v /path/to/mongodb-configuration-persistence:/bitnami/mongodb/conf bitnami/mongodb:latest
or using Docker Compose:
...
services:
mongodb:
...
volumes:
- 'mongodb_data:/bitnami/mongodb'
+ - /path/to/mongodb-configuration-persistence:/bitnami/mongodb/conf
...
Step 2: Edit the configuration
Edit the configuration on your host using your favorite editor.
$ vi /path/to/mongodb-configuration-persistence/mongodb.conf
Step 3: Restart MongoDB®
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.
Logging
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.
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:latest
or if you're using Docker Compose, update the value of the image property to bitnami/mongodb:latest
.
Step 2: Stop and backup the currently running container
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.
Step 3: Remove the currently running container
$ docker rm -v mongodb
or using Docker Compose:
$ docker-compose rm -v mongodb
Step 4: Run the new image
Re-create your container from the new image.
$ docker run --name mongodb bitnami/mongodb:latest
or using Docker Compose:
$ docker-compose up mongodb

- Decrease the size of the container. Node.js is not needed anymore. MongoDB® configuration logic has been moved to bash scripts in the rootfs folder.
3.6.9, 4.0.4 and 4.1.5 or later
- 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).
3.6.6-r16 and 4.1.1-r9
- 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.
3.2.7-r5
MONGODB_USER
parameter has been renamed toMONGODB_USERNAME
.
3.2.6-r0
- 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.
