All resources for the blog post titled "How to Deploy and Scale Strapi on a Kubernetes Cluster"
You can check out the source code of this article on GitHub. The code is separated into two folders, one for each part.

Now, for the purposes of this article, in case you don't have an NFS server available, we will use a simple NFS Server Provisioner, which we'll use only for example purposes. As mentioned before, using a managed solution from a cloud provider or a properly configured HA NFS server in your infrastructure is highly recommended. We'll install not the most up-to-date solution, but it should work for example purposes. We will follow the Quickstart found in the repo, mixed with this repo which does some small tweaks to make it work with K3d, which is summarized in the following commands run from the helm folder:
-
InfluxDB
Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.

We need a way of monitoring our cluster, the most recommended stack (but not the only one) is Prometheus, Alert Manager and Grafana. Prometheus is a monitoring system, and Grafana is a visualization system that can work as the frontend for Prometheus. The Prometheus community provides and easy way to install these tools via the Kube Prometheus Stack. This chart has many parameters you can configure, so we will not get into much detail here. The easiest way to install it is the following:

But for the purposes of this article, given that we want to show the process, we will run everything on the same computer. We will use the tool vegeta, and if you want to read more about it, you can read this article. Our Strapi project is based on the Getting started guide, therefore we have restaurants and categories, so we will use these endpoints.

Cluster Autoscaler, is a cluster autoscaling solution designed for any cloud provider.
-
Jaeger, another tracing solution that can work in tandem with OpenTelemetry.

Strapi
🚀 Strapi is the leading open-source headless CMS. It’s 100% JavaScript, fully customizable and developer-first.
Strapi is the leading open-source headless CMS based on NodeJS, and its projects can vary a lot between themselves, but also Kubernetes provides a lot of flexibility. Therefore, it's worth investing some time in the best practices to integrate them.

litmus
Litmus helps SREs and developers practice chaos engineering in a Cloud-native way. Chaos experiments are published at the ChaosHub (https://hub.litmuschaos.io). Community notes is at https://hackmd.io/a4Zu_sH4TZGeih-xCimi3Q
LitmusChaos, is a platform that helps you to run Chaos Engineering in your cluster to identify weaknesses and improvement opportunities.

keda
KEDA is a Kubernetes-based Event Driven Autoscaling component. It provides event driven scale for any container running in Kubernetes
The HPA will use by default only basic metrics like CPU and memory. If you implement your own metrics, you might want to switch the autoscaling to use those metrics instead. To achieve this, the most recommended tool would be to rely on the KEDA controller. This grants you more advanced options for horizontal autoscaling. To use it, you should install it via Helm, and then you can use it by replacing the HorizontalPodAutoscaler object with their ScaledObject custom object.

karpenter
Karpenter is a Kubernetes Node Autoscaler built for flexibility, performance, and simplicity.
Karpenter, is a cluster autoscaling solution that, for the moment, only works with AWS infrastructure, but helps you increase the number of nodes automatically depending on your Pods requirements.
-
Grafana
The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.
We need a way of monitoring our cluster, the most recommended stack (but not the only one) is Prometheus, Alert Manager and Grafana. Prometheus is a monitoring system, and Grafana is a visualization system that can work as the frontend for Prometheus. The Prometheus community provides and easy way to install these tools via the Kube Prometheus Stack. This chart has many parameters you can configure, so we will not get into much detail here. The easiest way to install it is the following:
-
FluentBit, is a logging processor that can help you to push all of your application logs to a central location like an ElasticSearch or OpenSearch cluster.
-
Falco, is a security project that can help you detect threats from within your cluster.
-
ArgoCD, a declarative tool to continuous delivery your applications via the GitOps way to K8s. Argo has other projects like Workflows or Rollouts very interesting as well.
