First, we need to optimize our application for deployment. We’ll start by configuring our config/autoload/global.php and config/autoload/local.php files to match Azure settings. Confirm that environment-specific variables, such as database credentials, are correctly set. It’s crucial to ensure that our composer.json file includes all necessary dependencies, including zendframework/zendframework.

Deploying Using Azure Portal

We access the Azure Portal to deploy our application. The steps involve:

Create a New Web App: Navigate to “Create a resource” and select “Web App.” Enter the required details like App name, Resource Group, and operating system.
Deploy Code: Use either a local Git repository or deploy directly from GitHub. For GitHub deployment, link our repository through Deployment Center.
Set Configurations: Adjust the Application settings to match the configurations in our global.php and local.php files.

Deploying via the Azure Portal ensures a straightforward and user-friendly approach with a visual interface.

Automating Deployment with Azure DevOps

Automating deployment with Azure DevOps increases efficiency and reduces manual errors. To do this:

Set Up Pipelines: Go to Azure DevOps, create a new pipeline, and connect it to our repository.
Define Build Steps: Specify build steps, including installing dependencies via Composer and running tests.
Release Pipeline: Create a release pipeline that targets our Azure Web App. This includes stages for deploying code leveraging Azure Web App deployment tasks.
