mongodb

MongoDB (from "humongous") is a scalable, high-performance document-oriented NoSQL database system. Instead of storing data in tables as is done in a "classical" relational database, MongoDB stores structured data as JSON-like documents with dynamic schemas, making integration with certain types of applications easier and faster.

Usage

Start a mongodb instance and connect to it from an application

$ docker run --name some-mongo -d tklx/mongodb
$ docker run --name some-app --link some-mongo:mongo -d app-that-uses-mongo

Authentication and Authorization

MongoDB does not require authentication by default, but it can be configured to do so. For more details about the functionality described here, please see the sections in the official documentation which describe authentication and authorization in more detail.

$ docker run --name some-mongo -d tklx/mongodb --auth

$ docker exec -it some-mongo mongo admin
connecting to: admin
> db.createUser({ user: 'some-user', pwd: 'some-pass', roles: [ { role: 'userAdminAnyDatabase', db: 'admin' } ] })
Successfully added user: {
        "user" : "some-user",
        "roles" : [
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                }
        ]
}

$ docker run -it --rm --link some-mongo:mongo tklx/mongodb \
     mongo -u some-user -p some-pass --authenticationDatabase admin \
     some-mongo/some-db
connecting to: some-mongo/some-db
> db.getName()
some-db
