Dockerized MongoDb

A docker image for running production-level MongoDb for landsat-api

MongoDB version

Different versions are built from different folders. The images are also hosted on DockerHub

Usage

To build the image go the folder of the version you need and execute the following command:

    docker build -t 'astrodigital/ad-monogodb' 3.0/.

You can also download the latest version for Docker hub;

    docker pull astrodigital/ad-monogodb:latest

Running the MongoDB server

Run the following command to start MongoDB:

    docker run -d -p 27017:27017 --name mongodb astrodigital/ad-monogodb:latest

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 mongodb

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>
        mongo landsat-api -u landsatuser -p EOsBKpZzXCiig1gdrtZI --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 -e MONGODB_PASS="mypass" -e LANDSAT_PASSWORD="landsatpss" -e USERNAME="landsatuser" --name mongodb astrodigital/ad-monogodb:latest

You can now test your new admin password:

    mongo admin -u admin -p mypass
    curl --user admin:mypass --digest http://localhost:27017/

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 --name mongodb -e AUTH=no astrodigital/ad-monogodb:latest

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:

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 --name mongodb -e AUTH=no -e OPLOG_SIZE=50 astrodigital/ad-monogodb:latest

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.
