Introduction to the Apps CLI Plugin for Streamlined Development and Deployment on Azure
The Apps CLI plugin is a vital tool for developers engaging in DevOps practices in the UAE. It facilitates the efficient development Azure and deployment of applications on Kubernetes. This plugin streamlines the management of application workloads and supply chains. Therefore, developers can concentrate on coding rather than dealing with complex configuration files. In this blog post, we will delve into the features, functionalities, and best practices associated with the Apps CLI plugin. This offers a thorough guide for developers eager to harness this powerful resource.
Overview of the Tanzu Application Platform, Its Role in DevOps, and Development Azure
The Tanzu Application Platform (TAP) is an integrated suite of tools that support DevOps practices in the UAE. It simplifies the development, deployment, and management of cloud-native applications. By abstracting the complexities of Kubernetes, TAP allows developers to work with higher-level abstractions. This means they do not have to handle Kubernetes resources directly. The platform includes several components, with the Tanzu CLI being the primary interface for developers.
Key Components of the Tanzu Application Platform for Development Azure
Tanzu CLI: This command-line interface provides a unified way to interact with various Tanzu products. It supports a plugin architecture that allows developers to extend its capabilities.
Apps CLI Plugin: This plugin focuses on application workloads and supply chains. It enables developers to deploy applications without manually configuring YAML files. As a result, it significantly reduces the overhead associated with Kubernetes deployments.
Insight CLI Plugin: This plugin helps developers scan images and packages for vulnerabilities. It ensures that applications are secure before they reach production.
Developer IDE Plugins: TAP provides plugins for popular IDEs like Visual Studio Code and IntelliJ IDEA. These improve the development experience by integrating directly with the Kubernetes runtime.
The Role of the Apps CLI Plugin in DevOps for Development Azure
The Apps CLI plugin is designed to manage two main abstractions within TAP: workloads and supply chains. Understanding these concepts is essential for effectively utilizing the plugin.
Workloads
In TAP, a workload represents the application itself. It is the unit of deployment that includes the application code, dependencies, and configurations needed to run on Kubernetes. The Apps CLI plugin allows developers to create, manage, and deploy workloads seamlessly. This enhances DevOps practices in the UAE.
Supply Chains
A supply chain is a Kubernetes Custom Resource (CR). It outlines the steps necessary to move an application from development to production. It includes various stages, such as building, testing, and deploying the application. The Apps CLI plugin simplifies how developers interact with these supply chains. Thus, they can focus on coding instead of the underlying infrastructure.
Installation and Setup
To start using the Apps CLI plugin, you need to have the Tanzu CLI installed on your machine. Follow this step-by-step guide to install the Tanzu CLI and the Apps CLI plugin:
Step 1: Install the Tanzu CLI
Download the Tanzu CLI: Visit the Tanzu Network and download the latest version of the Tanzu CLI.
Extract the CLI: After downloading, extract the contents of the tar file to a directory of your choice.
mkdir -p $HOME/tanzu
tar -xvf tanzu-framework-linux-amd64.tar -C $HOME/tanzu
Install the CLI: Move the Tanzu CLI executable to a directory in your PATH.
sudo install cli/core/v0.11.6/tanzu-core-linux_amd64 /usr/local/bin/tanzu
Verify the Installation: Check the installed version of the Tanzu CLI.

Step 2: Install the Apps CLI Plugin
Once the Tanzu CLI is installed, you can proceed to install the Apps CLI plugin.
Initialize the Tanzu CLI: This step prepares the CLI for use.
tanzu init
Install the Apps Plugin: Use the following command to install the Apps CLI plugin.
tanzu plugin install apps
Verify the Plugin Installation: Check that the plugin has been installed successfully.

Using the Apps CLI Plugin in DevOps for Development Azure
With the Apps CLI plugin installed, you can manage your application workloads and supply chains effectively. Below are some common commands and their functionalities.
Creating a Workload
To create a new workload, use the following command:
tanzu apps workload create <workload-name> --git-repo <repo-url> --git-branch <branch-name>
This command initializes a new workload based on the specified Git repository and branch. It automatically configures the necessary Kubernetes resources based on the application code.
Deploying a Workload
Once the workload is created, deploying it to the Kubernetes cluster is easy:
tanzu apps workload deploy <workload-name>
This command triggers the deployment process. It utilizes the defined supply chain to manage the various stages of deployment.
Managing Supply Chains
You can also interact with supply chains using the Apps CLI plugin. For instance, to list all available supply chains, run:
tanzu apps supply-chain list
This command provides an overview of the supply chains configured in your environment. It allows you to select the appropriate one for your workload.
Viewing Workload Status
To check the status of a deployed workload, use the following command:
tanzu apps workload get <workload-name>
This command retrieves the current status of the workload. It includes information about its deployment, health, and any associated resources.
Best Practices for Using the Apps CLI Plugin in Development Azure DevOps
To maximize the effectiveness of the Apps CLI plugin in your DevOps practices, consider these best practices:
1. Use GitOps Principles
Integrate your application development with GitOps principles. Store your application code and configurations in a Git repository. Use the Apps CLI plugin to manage deployments directly from the repository. This approach enhances collaboration and version control.
2. Automate Testing and Security Scans
Incorporate automated testing and security scans into your supply chains. Use the Insight CLI plugin to scan images and packages for vulnerabilities. This practice ensures your applications are secure and reliable.
3. Leverage IDE Plugins
Take advantage of the IDE plugins provided by TAP for Visual Studio Code and IntelliJ IDEA. These plugins offer features like code completion, debugging, and direct integration with Kubernetes. Thus, they enhance your development experience.
4. Monitor Workload Performance
Regularly monitor the performance of your workloads using Kubernetes monitoring tools. This practice allows you to identify and address any performance issues proactively. Therefore, you ensure your applications run smoothly in production.
Conclusion
The Apps CLI plugin for the Tanzu Application Platform is a powerful tool that simplifies the development and deployment of cloud-native applications on Kubernetes. By abstracting the complexities of Kubernetes resources and supply chains, it enables developers to focus on what matters most: writing code. By following best practices and leveraging the full capabilities of the plugin, developers can boost their productivity and confidently deliver high-quality applications.
As organizations in the UAE continue to adopt cloud-native technologies, mastering tools like the Apps CLI plugin will be essential for development Azure. Developers looking to excel in this dynamic landscape can benefit significantly. With a focus on Supply Chain Security Tools in VMware Tanzu, the Apps CLI plugin provides a robust framework for building and deploying applications efficiently, whether you’re a seasoned Kubernetes expert or just starting your journey.
