Deploying Frontend Application to Azure Kubernetes Service (AKS)

This guide covers the steps to build, push, and deploy a React application to Azure Kubernetes Service (AKS) using the CLI.

Prerequisites

  • Azure CLI installed and logged in
  • Azure Kubernetes Service (AKS) and Azure Container Registry (ACR) set up
  • Docker installed
  • kubectl installed
  • NodeJS installed

Reference - AKS

Build and Push Docker Image

Update Environment Variables in Dockerfile

Before building the Docker image, make sure that the environment variables in your Dockerfile are up to date. These variables are critical for your application to interact with Azure services like Cosmos DB, Blob Storage, and MongoDB.

Reference env

Build Docker Image

To build the Docker image, use the following command:

docker build -t <ACR_NAME>.azurecr.io/aistudy/frontend:latest .

Login to Azure Container Registry (ACR)

Before pushing the Docker image to ACR, you need to log in using your ACR credentials:

  1. Retrieve ACR credentials:

    az acr credential show --name <ACR_NAME>

  2. Log in to ACR:

    docker login <ACR_NAME>.azurecr.io

Push Docker Image

Push the Docker image to your ACR:

docker push <YOUR_ACR_NAME>.azurecr.io/aistudy/frontend:latest

Run Docker Image Locally (Optional)

If you want to test the Docker image locally, use the following commands:

Run Docker Image Locally

docker run -p 80:80 <YOUR_ACR_NAME>.azurecr.io/aistudy/frontend:latest

You can access the application at http://localhost.

Deploy to AKS

Update Variables in frontend-deployment.yml

Before run the Docker image in K8S, make sure that the environment variables in your frontend-deployment.yml are up to date. These variables are critical for your application to interact with Azure services like ACR_NAME, MIDDLEWARE_SERVICE_BASE_URL, APP_CLIENT_ID, CONTENT_GENERATOR_ENDPOINT, MIDDLEWARE_SERVICE_ACCESS_KEY and AZURE_KEYVAULT_URI (refer env).

Apply Kubernetes Deployment Locally

First, apply the Kubernetes deployment using the following command:

kubectl apply -f frontend-deployment.yml

Push Kubernetes Deployment to AKS

To deploy the application to AKS, ensure your kubectl is connected to your AKS cluster, then apply the deployment:

  1. Log in to Azure Log in to your Azure account using the Azure CLI: 
    az login
  2. AKS Login 
    az aks get-credentials --resource-group <YOUR_RESOURCE_GROUP> --name <AKS_NAME>
kubectl apply -f frontend-deployment.yml

This will deploy your application to the AKS cluster.
