Install Flagsmith on Kubernetes

How to Install Flagsmith on Kubernetes with Helm

This guide will walk you through the process of installing Flagsmith using Helm, the Kubernetes package manager, ensuring a smooth and efficient setup.

Prerequisites

Before we begin, ensure you have the following tools installed and configured:

• Kubernetes - Installed locally or in a public cloud provider
• kubectl - Configured to communicate with your Kubernetes cluster
• Helm - For managing Kubernetes applications like Flagsmith
• Kubernetes Ingress controller - For accessing the installation on a url

Step 1: Add the Helm chart repository

First, add the repository containing the Flagsmith helm chart:

helm repo add flagsmith https://flagsmith.github.io/flagsmith-charts
helm repo update
helm search repo flagsmith

Step 2: Create a namespace (optional)

Isolating applications within Kubernetes namespaces is a good practice. To deploy Flagsmith in its own namespace:

kubectl create namespace flagsmith

Step 3: Install Flagsmith using Helm

Now, you'll install Flagsmith. The helm chart name is "flagsmith":

helm install flagsmith flagsmith/flagsmith --namespace flagsmith --create-namespace

Step 4: Verify the installation

After installation, verify that your Flagsmith deployment is running smoothly:

kubectl get pods --namespace flagsmith
kubectl get all --namespace flagsmith

Step 5: Customize the Flagsmith installation (optional)

This process may require customizing your deployment through a customized values.yaml file, which specifies configuration options.

helm install flagsmith flagsmith/flagsmith --values values.yaml --namespace flagsmith

Step 6: Access Flagsmith

Accessing Flagsmith will depend on your chosen service configuration (LoadBalancer, NodePort, or Ingress). For Ingress access, ensure an Ingress controller is operational in your cluster.

Follow the instructions in the helm install notes, the output of Step 3.
