Charmed MongoDB K8s Documentation

Overview

MongoDB is a popular NoSQL database application. It stores its data with JSON-like documents creating a flexible user experience with easy-to-use data aggregation for data analytics. In addition, it is a distributed database, so vertical and horizontal scaling come naturally.

Applications like MongoDB must be managed and operated in production environments. This means that MongoDB application administrators and analysts who run workloads in various infrastructures should be able to automate tasks for repeatable operational work. Technologies such as software operators encapsulate the knowledge, wisdom and expertise of a real-world operations team and codify it into a computer program that helps to operate complex server applications like MongoDB and other databases. Canonical has developed an open-source operator called Charmed MongoDB for this purpose.

The Charmed MongoDB Kubernetes (K8s) operator deploys and operates MongoDB in multi-cloud environments using Kubernetes. Software operators are principally associated with Kubernetes, an open-source container orchestration system that facilitates the deployment and operation of complex server applications. As a concept, however, they can be applied equally to application and infrastructure operations on platforms beyond Kubernetes. They are especially popular on Kubernetes because they can help to reduce the complexity of operations on this powerful but complex platform.

Charmed MongoDB (K8s Operator) is an enhanced, open source and fully-compatible drop-in replacement for the MongoDB Community Edition with advanced MongoDB enterprise features. It simplifies the deployment, scaling, design and management of MongoDB in production in a reliable way. In addition, you can use the operator to manage your MongoDB clusters with automation capabilities. It also offers replication, TLS, password rotation, easy-to-use application integration, backup, restore, and monitoring.

Aside from a Kubernetes operator, Canonical developed another operator called Charmed MongoDB (VM operator) that operates on physical, Virtual Machines (VM) and a wide range of cloud and cloud-like environments, including AWS, Azure, OpenStack and VMWare.

Notice: Due to limitations in the MongoDB driver the MongoDB replica set is not accessible outside of the k8s environment. In several months we will implement a proxy via mongos which will make this possible. Until then you can try out the MongoDB 6/edge charm on the VM Operator which does not face this limitation

Software and releases

Charmed MongoDB (K8s Operator) uses the Charmed MongoDB snap package, which offers more features than the MongoDB Community version, such as backup and restores, monitoring and security features.

Charm version, environment and OS

A charm version is a combination of both the application version and / (slash) the channel, e.g. 6/stable, 6/candidate, 6/edge. The channels are ordered from the most stable to the least stable, candidate, and edge. More risky channels like edge are always implicitly available. So, if the candidate is listed, you can pull the candidate and edge. When stable is listed, all three are available.

You can deploy the charm a stand-alone machine or cloud and cloud-like environments, including AWS, Azure, OpenStack and VMWare.

The upper portion of this page describes the Operating System (OS) where the charm can run. For example, 6/stable is compatible and should run on a machine with Ubuntu 22.04 OS.

Supported architectures

The charm should be running on architectures that support AVX

To check your architecture please execute

grep avx /proc/cpuinfo

or

grep avx2 /proc/cpuinfo

Supported Juju versions

At the current moment the MongoDB K8S charm supports and Juju 3.x
