Deploy Spring Boot REST API on Azure Kubernetes Service with Azure Database for PostgreSQL

Deploy Spring Boot REST API on Azure Kubernetes Service with Azure Database for PostgreSQL

Create an Azure Database for PostgreSQL server. Prepare Java Spring Boot application for AKS. Deploy Azure Container Registry (ACR). Deploy Java application to Kubernetes with Kustomize. Deploying a Spring Boot REST API on Azure Kubernetes Service with Azure Database for PostgreSQL.

Connecting AKS Applications to Azure PostgreSQL with AAD Pod Identities.

In this post, We will look at how to run a Java Spring Boot application on Azure Kubernetes Service (AKS) and connects to Azure PostgreSQL using Azure AD Pod identity. Azure Kubernetes Service (AKS) is a managed Kubernetes service that lets you quickly deploy and manage applications based on microservices.

Azure Active Directory pod-managed identities uses Kubernetes primitives to associate managed identities for Azure resources and identities in Azure Active Directory (AAD) with pods.

What we’ll cover in this post:

  • Create an AKS cluster and Pod Identity.
  • Create an Azure Database for PostgreSQL server.
  • Prepare Java Spring Boot application for AKS.
  • Deploy Azure Container Registry (ACR).
  • Deploy Java application to Kubernetes with  Kustomize.

The following diagram shows the architecture of the above steps:
