frodenas/mongodb repository overview

⁠MongoDB Dockerfile

A Dockerfile that produces a Docker Image for MongoDB⁠.

⁠MongoDB version

The master branch currently hosts MongoDB 2.6.

Different versions of MongoDB are located at the github repo branches⁠.

⁠Usage

⁠Build the image

To create the image frodenas/mongodb, execute the following command on the docker-mongodb folder:

$ docker build -t frodenas/mongodb .

⁠Run the image

To run the image and bind to host port 27017:

$ docker run -d --name mongodb -p 27017:27017 frodenas/mongodb

If you want also to expose the MongoDB http interface, you will need also to expose port 28017:

$ docker run -d --name mongodb -p 27017:27017 -p 28017:28017 frodenas/mongodb --httpinterface

The first time you run your container, a new user mongo with all privileges will be created with a random password. To get the password, check the logs of the container by running:

docker logs <CONTAINER_ID>

You will see an output like the following:

========================================================================
MongoDB User: "mongo"
MongoDB Password: "ZMUgiS3O1kJH1ec5"
MongoDB Database: "admin"
MongoDB Role: "dbAdminAnyDatabase"
========================================================================

⁠Credentials

If you want to preset credentials instead of a random generated ones, you can set the following environment variables:

• MONGODB_USERNAME to set a specific username
• MONGODB_PASSWORD to set a specific password

On this example we will preset our custom username and password:

$ docker run -d \
    --name mongodb \
    -p 27017:27017 \
    -e MONGODB_USERNAME=myusername \
    -e MONGODB_PASSWORD=mypassword \
    frodenas/mongodb

⁠Databases

If you want to create a database at container's boot time, you can set the following environment variables:

• MONGODB_DBNAME to create a database
• MONGODB_ROLE to grant the user a role to the database (by default dbOwner)

On this example we will preset our custom username and password and we will create a database with the default role:

$ docker run -d \
    --name mongodb \
    -p 27017:27017 \
    -e MONGODB_USERNAME=myusername \
    -e MONGODB_PASSWORD=mypassword \
    -e MONGODB_DBNAME=mydb \
    frodenas/mongodb

⁠Extra arguments

When you run the container, it will start the MongoDB server without any arguments. If you want to pass any arguments, just add them to the run command:

$ docker run -d --name mongodb -p 27017:27017 frodenas/mongodb --smallfiles

⁠Persistent data

The MongoDB server is configured to store data in the /data directory inside the container. You can map the container's /data volume to a volume on the host so the data becomes independent of the running container:

$ mkdir -p /tmp/mongodb
$ docker run -d \
    --name mongodb \
    -p 27017:27017 \
    -v /tmp/mongodb:/data \
    frodenas/mongodb
