![]() ![]() Docker Componentsīefore diving into implementation details, let’s take a moment to introduce some of Docker’s basic concepts. You’ll also learn how to host a simple Flask app and how to use Docker volumes to persist data in a Docker container. In this article, you’ll learn the best practices for running a MongoDB container. If you are developing multiple applications, you can start multiple containers together using a docker-compose.yaml file. Furthermore, during development, it is easier to start a Docker instance than manually configure a server. If you want to use your MongoDB database across several machines, using Docker containers for hosting MongoDB is a great approach – you can easily create new isolated instances. For production, you may custom-build a container with MongoDB’s enterprise version. There is an official image available on Docker Hub containing the MongoDB community edition, used in development environments. MongoDB can be run in a Docker container. You can also leave fields empty in situations where a lot of data is missing. You can just input the data, and new fields will be created. NoSQL databases are useful for storing such data. In the real world, much data is unstructured-it doesn’t follow a specific schema. It uses a JSON-like storage model and doesn’t require a predefined database schema. MongoDB is a NoSQL database service with seamless performance and options for scaling. Thanks to Docker’s lightweight runtime and ability to run processes in isolation, multiple containers can run at the same time on the same VM or server. These containers can be run on any machine, as well as in a public or private cloud. If you’re interested in a simple and containerized approach to building software then check us out.ĭocker is a powerful development platform that enables users to containerize software. This article covers using MongoDB in a containerized setting. We make building software simpler and therefore faster. To add an item to a collection, you can pass a JavaScript object into db.insertOne(). We’ll use characters as the name of the collection. Here, we need to put the character into a collection. We’re going to add a character into the game-of-thrones. You can use the use command to create and switch to a new database. It is not part of the command.įor this article, we’ll create a database called game-of-thrones. Note: The > in the code above signifies the Mongo Shell. (By default, you should be on the test database). You can see the currently selected database with the db command. Note: Make sure you keep the mongod window open! You won’t be able to interact with the Mongo Shell if you close the mongod window.įirst, we need a database to work with. To open up the Mongo Shell, you open another command line window and run mongo. One way to add items to a MongoDB database is through the Mongo Shell. Each collection can only contain one type of data.įor example, one collection can be used for books, one collection for users, one collection for toys, and so on. You have an unlimited supply of boxes in each room. You can store as much information as you want. Each database is responsible for storing information about one application. It contains many rooms.Įach room is a database. ![]() To make it easier to understand, you can think of MongoDB as a building. Each database contains multiple collections. MongoDB lets you store things (called documents) inside databases. Keep the mongod window running when you want to work with your local MongoDB. You can start MongoDB on your computer with the mongod command. You should get a response similar to the following: mongo - version Starting MongoDB Once you have completed the installation process, try typing mongo -version into your command line. You can install MongoDB by following these instructions ( Mac and Windows). You need to install MongoDB on your computer before you can connect to it. Today, I want to share how to create and connect to a local MongoDB Database. ![]() And I like to connect to a database on my computer because it speeds up dev and test-related work. I always use MongoDB as a database when I work on an app. ![]()
