Full Description

mongodb-3.4

A docker mongodb version 3.4 with user, password and engine options.

Usage

To create the image dubc/mongodb-3.4, execute the following command on the mongodb-3.4 folder:

    docker build -t dubc/mongodb-3.4 .

Running the MongoDB server

Run the following command to start MongoDB:

    docker run -d -p 27017:27017 -p 28017:28017 --name mongodb-3.4 dubc/mongodb-3.4

The first time that you run your container, a new random password will be set.
To get the password, check the logs of the container by running:

    docker logs <CONTAINER_ID>

You will see an output like the following:

    ========================================================================
    You can now connect to this MongoDB server using:

        mongo admin -u admin -p 5elsT6KtjrqV --host <host> --port <port>

    Please remember to change the above password as soon as possible!
    ========================================================================

In this case, 5elsT6KtjrqV is the password set.
You can then connect to MongoDB:

     mongo admin -u admin -p 5elsT6KtjrqV

Done!

Setting a specific password for the admin account

If you want to use a preset password instead of a randomly generated one, you can
set the environment variable MONGODB_PASS to your specific password when running the container:

    docker run -d -p 27017:27017 -p 28017:28017 -e MONGODB_PASS="mypass" --name mongo-3.4 dubc/mongodb-3.4

You can now test your new admin password:

    mongo admin -u admin -p mypass
    curl --user admin:mypass --digest http://localhost:28017/

Setting a specific user:database

If you want to use another database with another user

docker run -d -p 27017:27017 -p 28017:28017 -e MONGODB_USER="user" -e MONGODB_DATABASE="mydatabase" -e MONGODB_PASS="mypass" --name mongo-3.4 dubc/mongodb

You can now test your new credentials:

mongo mydatabase -u user -p mypass

Note: with mongo 3.x an admin user is also created with the same credentials

mongo admin -u user -p mypass

Run MongoDB without password

If you want to run MongoDB without password you can set the environment variable AUTH to specific if you want password or not when running the container:

    docker run -d -p 27017:27017 -p 28017:28017 -e AUTH=no dubc/mongodb-3.4

By default is "yes".

Run MongoDB with a specific storage engine

In MongoDB 3.0 there is a new environment variable STORAGE_ENGINE to specific the mongod storage driver:

    docker run -d -p 27017:27017 -p 28017:28017 -e AUTH=no -e STORAGE_ENGINE=mmapv1 dubc/mongodb-3.4

By default is "wiredTiger".

Change the default oplog size

In MongoDB 3.0 the variable OPLOG_SIZE can be used to specify the mongod oplog size in megabytes:

    docker run -d -p 27017:27017 -p 28017:28017 -e AUTH=no -e OPLOG_SIZE=50 dubc/mongodb-3.4

By default MongoDB allocates 5% of the available free disk space, but will always allocate at least 1 gigabyte and never more than 50 gigabytes.

Volume

You can access the volume /data/db via:

    -v /your/host/dir:/data/db
