Prerequisites for Running Magento 2 on Kubernetes

Before diving into the process of setting up and running a Magento 2 store on Kubernetes, it’s important to ensure you have a solid understanding of the key concepts and requirements. This article assumes you have a fundamental grasp of operating Magento 2, working with containers (Docker), and the basic principles of Kubernetes.

Understanding Magento 2, Containers, and Kubernetes Basics

To successfully deploy and manage your Magento 2 store on Kubernetes, you should have a working knowledge of Magento 2 as an ecommerce platform, as well as the basics of containerization with Docker and the container orchestration capabilities provided by Kubernetes.

System Requirements

The Kubernetes cluster you use for your Magento 2 deployment should meet the following system requirements:

• At least 4 CPUs and 8 GB of RAM available
• An NGINX Ingress Controller installed to provide access to your Magento 2 application
• A default Storage Class configured to handle persistent storage for your Magento 2 components

Essential Tools

In addition to the Kubernetes cluster, you’ll need the following tools to simplify the deployment process:

1. kubectl with the correct context configured to interact with your Kubernetes cluster
2. make (optional but recommended) to streamline the deployment and management of your Magento 2 application on Kubernetes

By ensuring you have the necessary prerequisites in place, you’ll be well-positioned to successfully deploy and manage your Magento 2 store on the Kubernetes platform, taking advantage of its scalability, high availability, and deployment automation features.

Step 1: Create a Minimal Magento 2 Deployment

To begin our Magento 2 deployment on Kubernetes, we’ll need a container running the Magento application itself. When deploying a PHP web application on Kubernetes, there are various patterns to consider, such as the all-in-one container, NGINX and PHP-FPM in a single container, a single pod running two containers, and web server and PHP in separate pods. For this initial deployment, we’ll be using the NGINX and PHP-FPM in a single Magento container configuration.

Magento Container Image

The Magento container will be the foundation of our Kubernetes deployment. It will include both the NGINX web server and the PHP-FPM process, allowing us to manage and configure the application environment more effectively.

Configuring Magento with Environment Variables

When deploying Kubernetes applications, it’s best practice to configure each program by setting environment variables on its container. Magento 2 has the ability to pick up settings from the environment, enabling us to control environment-specific configuration like database credentials using these environment variables.

Managing Logs

Another important consideration when deploying Magento 2 on Kubernetes is ensuring all relevant logs survive container restarts and are easily accessible. The simplest solution would be to use a PersistentVolume for the var/log and var/reports directories. However, to satisfy both log persistence and performance, multiple options are available, such as using a sidecar container or logging directly to stdout.

Cron Jobs for Magento on Kubernetes

Magento relies on cron jobs for several of its critical features. In a traditional deployment scenario, you would typically assign one of the hosts to run the cronjobs and configure them directly via crontab. However, such a setup would not work well with Kubernetes, as there is no single Magento instance (container) that is guaranteed to be always running.

To address this challenge, we’ll utilize a Kubernetes CronJob to execute the bin/magento cron:run command every minute. This approach allows us to delegate the responsibility of scheduling and running cron jobs to Kubernetes, which will start a new Pod for each execution and run the given commands until completion.

By leveraging Kubernetes CronJobs, we can ensure that the necessary cron jobs are executed reliably, even in a dynamic Kubernetes environment where the individual Magento containers may be scaling up or down based on demand. This setup provides a robust and scalable solution for managing the critical cron-based processes that power your Magento store running on the Kubernetes platform.

The Magento 2 on Kubernetes deployment process involves several key elements. First, we’ll need to create a minimal Magento 2 deployment using Kubernetes. This includes setting up the Magento container image, configuring Magento with environment variables, and ensuring proper log management. Additionally, we’ll address the critical issue of cron jobs for Magento on Kubernetes, leveraging Kubernetes CronJob resources to handle scheduled tasks reliably.

By following the steps outlined in this section, online retailers can seamlessly deploy and manage their Magento 2 stores on the Kubernetes platform, unlocking the benefits of enhanced scalability, high availability, and streamlined deployment processes. This approach empowers merchants to focus on delivering exceptional ecommerce experiences to their customers, while Kubernetes handles the underlying infrastructure challenges.

Deploying Magento 2 on Kubernetes: Architectural Considerations

When deploying a PHP web application like Magento 2 on the Kubernetes container orchestration platform, there are various architectural patterns to consider. Each of these patterns offers unique advantages and trade-offs in terms of complexity, resource allocation, and file sharing between containers. Let’s explore the key options for running Magento 2 on Kubernetes:

PHP Web Application Pod Patterns

The choice of pod pattern can significantly impact the deployment, scalability, and manageability of your Magento 2 application on Kubernetes. These patterns include the all-in-one container, NGINX and PHP-FPM in a single container, a single pod running two containers, and web server and PHP in separate pods.

All-in-One Container

The most straightforward arrangement is to have a single container running Apache 2 with mod_php in a single process. This all-in-one container is the easiest to configure and manage, but you might want to consider using NGINX to serve static content after all – either as a dedicated pod or a caching reverse-proxy.

NGINX and PHP-FPM in a Single Container

In this configuration, NGINX and PHP-FPM are running in a single container, communicating over the network instead of a socket. This way, you don’t need a process manager like supervisord, and you can assign specific readiness and liveliness probes to each component as well as have more control over resource allocation.

Single Pod Running Two Containers

In this configuration, NGINX and PHP-FPM are running in separate containers, communicating over the network. This allows you to scale PHP and NGINX pods independently, but you need to configure proper persistent volumes for static assets, as you cannot use an emptyDir volume to share files between the pods.

Web Server and PHP in Separate Pods

This pattern is quite similar to the previous one, except it allows you to scale PHP and NGINX pods independently. As with the single pod running two containers, you cannot use an emptyDir volume here to share files between the pods and need to configure proper persistent volumes for static assets.

Magento 2 with Kubernetes on AWS Cloud

Deploying Magento 2 on Kubernetes in the AWS cloud offers several benefits, including enhanced scalability, improved resource utilization, high availability and disaster recovery, simplified deployment and integration, and portability and flexibility.
