Base docker image to run a MongoDB database server

Different versions are built from different folders. If you want to use MongoDB, please check our tutum/mmongodb image: https://github.com/tutumcloud/tutum-docker-mongodb

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

    docker build -t tutum/mongodb 2.6/ .

Run the following command to start MongoDB:

    docker run -d -p 27017:27017 -p 28017:28017 tutum/mongodb

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!

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" tutum/mongodb

You can now test your new admin password:

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

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 tutum/mongodb

By default is "yes".

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 tutum/mongodb:3.0

By default is "wiredTiger".

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 tutum/mongodb:3.0

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.
