Azure Jenkins Complete Guide

Azure Jenkins is a game-changer for DevOps teams. By integrating Jenkins with Azure, you can create a seamless CI/CD pipeline that automates testing, building, and deployment of your applications.

With Azure Jenkins, you can take advantage of Azure's scalability and reliability to run your Jenkins jobs. This means you can scale your Jenkins infrastructure up or down as needed, without worrying about resource constraints.

Jenkins can be easily integrated with Azure DevOps, allowing you to leverage the full range of Azure's features, including source control, project planning, and continuous integration.

Jenkins is an open-source automation server that helps developers build, test, and deploy their software projects. It was originally created by Kohsuke Kawaguchi in 2004.

Jenkins can be integrated with various tools and services to automate different stages of the software development process, such as building, testing, and deployment.

Jenkins is highly customizable, allowing users to create custom plugins and pipelines to fit their specific needs.

Jenkins can be used to automate tasks such as continuous integration, continuous delivery, and continuous deployment.

To use Azure Jenkins, you need to have an Azure Service Principal in your Jenkins instance. This is a crucial step that sets the foundation for successful deployment.

First, create an Azure Service Principal through Azure CLI or Azure portal. This will give you the necessary credential information to proceed.

Next, open your Jenkins dashboard and go to Credentials, where you'll add a new Microsoft Azure Service Principal with the credential information you just created.

You'll also need to install Azure CLI in the Jenkins Host.

To deploy to Azure Web App, you'll need to create a Web App in Azure portal or through Azure CLI. We support both Web App (hosted on Windows) and Web App On Linux.

Here's a quick summary of the prerequisites:

By following these steps, you'll be well on your way to setting up Azure Jenkins and deploying your applications successfully.

You can deploy your code into Azure services using Jenkins plug-ins as part of your Jenkins CI/CD pipelines. Deploying into Azure App Service and Azure Container Service lets you stage, test, and release updates to your applications without managing the underlying infrastructure.

To deploy to Azure App Service on Linux, you can follow the tutorial to get started. You can also use the Azure CLI Plugin in the Build Steps to deploy your application to Azure.

To scale your build automation on demand, you can add build agents to your existing Jenkins deployment. You can run these build agents on Azure virtual machines by using the Azure VM Agents plug-in.

You can specify a different base image from Azure Marketplace or use a custom image when scaling agents. Alternatively, you can run a container as an agent in Azure Container Service with Kubernetes or Azure Container Instances.

Here are the two options for scaling agents:

When creating a VM and installing Jenkins, you can specify the size of the VM. Selecting the correct VM server size depends on the size of the expected workload. The Jenkins community maintains a selection guide to help identify the configuration that best meets your requirements.

Continuous Integration and Delivery are key concepts in Azure Jenkins that help you build, test, and deploy your applications more efficiently. Continuous Integration (CI) automates the process of building and testing your code whenever new changes are committed to the repository.

Jenkins can be configured to trigger builds and tests automatically, helping you identify and fix bugs early in the development lifecycle. This reduces the risk of bigger problems later on.

Here are some benefits of using Continuous Delivery (CD):

By integrating CI and CD into your Azure Jenkins workflow, you can streamline your development process and get your applications to market faster.

Continuous Delivery (CD) is the next step after Continuous Integration (CI). Once the code has been built and tested successfully through CI, CD automates the process of deploying it to production environments.

This allows development teams to release new features and fixes to users more frequently and reliably. CD reduces the risk of errors and inconsistencies that can occur during manual deployments.

By automating deployments, CD saves time and effort, and also ensures that the deployment process is consistent and repeatable.

Continuous Integration (CI) is a game-changer for developers, allowing them to merge their code changes into a shared repository frequently.

This process helps identify and fix bugs early in the development lifecycle before they become bigger problems later.

Jenkins can be configured to automatically trigger builds and tests whenever new code is committed, making the development process smoother and more efficient.

By doing so, developers can catch errors and issues quickly, reducing the risk of downstream problems and improving overall code quality.

Organizing your Azure resources into separate resource groups is a good practice, especially for production and development/test environments, as it allows you to monitor each environment's resources and roll up billing costs by resource group.

You can deploy Azure Monitor to monitor CPU usage, which can send a notification if CPU usage exceeds 80 percent.

Deleting resources as a set is useful for test deployments, so you can easily get rid of them when they're no longer needed.

Azure Monitor can also notify a designated user if the VM fails or becomes unavailable, giving you peace of mind and quick response times.

You can install the Azure Jenkins plugin through the Jenkins update center or manually. To update the plugin in the Jenkins update center, navigate to Manage Jenkins -> Manage Plugins, search for the plugin, and follow the prompts.

There are two ways to manually install the plugin: cloning the repo and building it, or installing it from the Jenkins dashboard. To manually install the plugin, clone the repo and build it using mvn package.

To upload the plugin, go to the Advanced tab, under the Upload Plugin section, click Choose File, and select the .hpi file in the target folder of your repo. After installation, restart your Jenkins instance.

You can install either the Azure CLI Plugin or the Azure App Service Plugin manually. The steps are similar for both plugins: clone the repo, build it, upload the .hpi file, and restart your Jenkins instance.

Here are the general steps to manually install the plugin:

A server is a crucial component in many software projects, and one popular example is the Jenkins Server. Jenkins is a free and open-source automation server that helps set up continuous integration and delivery for your projects.

You can host your Jenkins deployment in Azure, which is a cloud platform that offers a range of services for building, deploying, and managing applications.

To install plugins in Jenkins, you can use the update center or manually install them.

You can find the plugins in the Jenkins update center by going to Manage Jenkins -> Manage Plugins and searching for the plugin you want to install.

If you want to try the latest feature before it's officially released, you can manually install the plugin.

To do this, first clone the repo and build it using the command mvn package.

Next, open your Jenkins dashboard and go to Manage Jenkins -> Manage Plugins.

Then, go to the Advanced tab and click Choose File under the Upload Plugin section.

Select the .hpi file in the target folder of your repo and click Upload.

Finally, restart your Jenkins instance after the install is completed.

Version 0.6 (2017-11-3) was a significant update that fixed the pipeline with exported environment variables support. This change likely improved the stability and efficiency of the system.

The pipeline is now able to handle exported environment variables, which can be a game-changer for developers working with complex systems.

In version 1.0.0, released on June 17, 2019, the Jenkins version was bumped to 2.60.3.

This update also introduced support for swapping slots, a feature that can be useful for developers who need to switch between different environments or configurations.

The version 1.0.0 update improved the overall stability and functionality of the system, making it easier to manage and deploy applications.

Here's a summary of the key changes in version 1.0.0:

To get started with Azure Jenkins, you'll need to create a Jenkins Master in Azure using an Ubuntu VM. This is the foundation of your Jenkins setup.

You can create a Jenkins Master in Azure using Ubuntu VM by following the lab tasks outlined below:

These tasks will guide you through the process of setting up your Jenkins Master in Azure.
