Step 1: Prerequisites Set Up Azure Resources: Azure App Service: Create an App Service instance for your application. Azure Container Registry (ACR): Create a registry for storing your application’s container image. Prepare Your GitHub Repository: Ensure your Spring Boot application source code is in a GitHub repository. Include a Dockerfile in your project for containerization (see Step 2). Install Azure CLI: Download and install Azure CLI . Log in to Azure: az login Enable Admin User in ACR: Go to the Azure portal > ACR > Settings > Access Keys. Enable Admin user and note down the username and password . Step 2: Add a Dockerfile Navigate to the root of your Spring Boot application project. Create a Dockerfile with the following content: FROM eclipse-temurin: 17 -jdk-a...

This guide provides a comprehensive, step-by-step process for deploying a Spring Boot application to Azure App Service using Azure DevOps for Continuous Integration (CI) and Continuous Deployment (CD). It covers essential steps, starting from creating an Azure App Service, setting up a Spring Boot project in Eclipse or IntelliJ, and pushing the code to Azure Repos, to configuring automated build and deployment pipelines in Azure DevOps. By the end of this guide, you'll have a fully automated deployment pipeline that allows for seamless code integration and deployment of your Spring Boot application to Azure, enhancing development efficiency and reliability. Here is the general architecture diagram that we will be deploying. 1. Create Azure App Service Sign in to Azure Portal : Log in to the Azure portal using your Azure account. Create an App Service : Go to the Create a resource section. Search for App Service and click on it. Click Create to start the process. Configure the Ap...

This guide will walk you through integrating Azure OpenAI with a Spring Boot application using the spring-ai-azure-openai-spring-boot-starter dependency. You will learn how to configure, develop, and test an end-to-end solution. Step 1: Set Up Your Azure OpenAI Resource 1.1. Create Azure OpenAI Resource Log in to Azure Portal . Navigate to Create a resource and search for Azure OpenAI . Follow the prompts to create a new Azure OpenAI resource. 1.2.

Here’s an end-to-end example of integrating Spring Security with Spring LDAP for authentication in a Spring Boot  application. 1. Set Up Local LDAP Server To install and run an LDAP server locally, you can use Apache Directory Server or OpenLDAP . Here, I'll use Apache Directory Server (Apache DS) because it's easy to set up and works well with Spring Boot. 1.1. Install Apache Directory Server Download Apache Directory Server from the official site . Choose the latest version based on your operating system. Install Apache Directory Server : Extract the downloaded ZIP or tar.gz file to a directory of your choice. Open a terminal or command prompt and navigate to the directory where you extracted the server. Start Apache Directory Server : Run the following command to start the LDAP server: bin/apacheds .sh start For Windows, use bin/apacheds.bat start . Access the Apache Directory Studio (optional) for easier interaction with your LDAP server: Download Apache Directory Stud...

To integrate Spring Boot with Ollama (an AI platform), you can create a Spring Boot application that uses Spring AI support for Ollama to interact with its AI models.
