As enterprises move to cloud computing and containers become more popular in software development, Kubernetes lets users deploy, scale, and manage containers easily. This platform makes it effortless to run and manage applications throughout their life cycle.
Though it’s always been a challenge to run databases and stateful applications in Kubernetes, it’s even more difficult to manage them in a production setting. Every enterprise needs a qualified operator to deploy and manage its databases efficiently.
A production-grade operator has the necessary skills and experience to run databases effectively, ensuring they are always available and perform at optimal levels. It manages its life cycle on Kubernetes so that its data is protected and always available when needed.
This blog will teach you about MongoDB and how to deploy and manage MongoDB on Kubernetes.
MongoDB is a powerful NoSQL database that uses flexible JSON-like documents with optional schemas. This means that fields can vary from document to document, and data structure can be changed over time. To make the smooth working of data, the document model used by MongoDB maps to the objects in your application code.
With MongoDB, you can meet the needs of today’s businesses by creating rich, scalable applications. It is developed by MongoDB Inc. and is classified as a cross-platform document-oriented database program.
MongoDB is excellent for storing and querying large amounts of unstructured data. It’s frequently used in real-time analytics, big data, and other performance-intensive tasks because it can handle large data sets effortlessly. In addition, it provides a lot of features such as indexing, sharding, and aggregation. These make MongoDB very powerful and ideal for high-performance use cases.
MongoDB also supports automatic sharding, which allows horizontal database scaling by distributing data across multiple servers. Additionally, it can be used as a replica set, providing automatic failover and data redundancy in the event of failure.
Running MongoDB on Kubernetes involves several steps; here is a complete guide on how to run MongoDB on Kubernetes:
The first step in the process of running MongoDB on Kubernetes is to create a cluster of Kubernetes. By using a tool like minikube, Google Kubernetes Engine (GKE), or Amazon Elastic Kubernetes Service (EKS). This will provide the necessary infrastructure for running MongoDB.
Next, you will need to create a deployment that defines how many replicas of MongoDB you want to run, what image to use, and how to configure the container. This is typically done using a Kubernetes YAML file. You can use the official MongoDB image from Docker Hub or the MongoDB Enterprise Kubernetes Operator.
To access the MongoDB replicas from outside the cluster, you must create a service that acts as a load balancer. This is typically done using another YAML file.
MongoDB requires persistent storage for its data. You can use Kubernetes StatefulSets to create and manage MongoDB pods with persistent storage. You can configure a storage class or use a cloud provider’s storage service to create a persistent volume for the MongoDB pods.
Once you have your deployment and service defined, you can use the kubectl command-line tool to create and manage your MongoDB pods.
If you need to scale up or down your MongoDB deployment, you can do it using the kubectl command.
It’s important to monitor your MongoDB deployment and to be aware of the performance metrics of your pods and the resources they are using. You can use tools such as Prometheus and Grafana to monitor and visualize your MongoDB deployment.
To ensure the safety of your data and to be able to recover from failures, it’s important to have a backup and restore strategy. You can use the MongoDB Enterprise Kubernetes Operator to automate the backup and restore process.
It’s important to note that MongoDB is a complex system, and there are several ways to run MongoDB on Kubernetes.
For more detailed instructions, follow MongoDB’s official documentation on how to run MongoDB on Kubernetes and consult with MongoDB experts if you encounter any issues.
There are several open-source solutions available to run MongoDB on Kubernetes. Some of the common and renowned open-source options include –
MongoDB Inc created this operator of Kubernetes. The purpose of this operator is to make it easy to deploy, manage, and scale MongoDB clusters on Kubernetes. It provides features such as backup and restores, automatic failover, and scaling.
For Kubernetes, Helm is a package manager allowing you to install and manage applications on a Kubernetes cluster conveniently. Several Helm charts are available for MongoDB, making it easy to deploy MongoDB on a Kubernetes cluster.
It is a Kubernetes resource that makes it easy to manage stateful applications on a Kubernetes cluster. You can use this solution to create and manage MongoDB pods with persistent storage, which makes it easy to deploy MongoDB on a Kubernetes cluster.
You can also use custom YAML files to deploy MongoDB on a Kubernetes cluster. It allows you to have complete access to your MongoDB deployment configuration and make any customizations you require.
This open-source operator allows you to deploy and manage MongoDB clusters on Kubernetes. The features provided by this operator include automatic failover, backup and restore, and scaling.
OperatorHub.io is a central repository or platform for discovering and deploying Kubernetes Operators. Here, Kubernetes Operators stands for software extensions to Kubernetes. They make it convenient to manage applications, such as databases, message queues, and other services, on top of Kubernetes.
It allows users to browse and deploy Operators from a curated catalog, and to submit their Operators for inclusion in the catalog.
Each of these solutions has its pros and cons, and the best choice for you will rely on your particular use case and requirements. It is substantial to thoroughly evaluate each option and consult with experts if you encounter any issues.
This blog post summarized and highlighted how to deploy MongoDB on Kubernetes and manage it. This is an important technical decision that might impact various business metrics, so choosing the right solution to deploy and manage MongoDB is crucial
An important thing to remember when choosing a database solution is that it should provide a way to deploy the database and enable your teams to execute various management and maintenance tasks without drowning in MongoDB complexity.
