Azure DevOps Pipeline Concepts

Azure DevOps Pipeline Concepts encompass several fundamental ideas and components that are integral to understanding and effectively using Azure Pipelines, Microsoft's CI/CD service. Here are some key concepts:

• Pipeline:
  A pipeline is the core element of Azure DevOps Pipelines. It represents the entire workflow for building, testing, and deploying your application. Pipelines are defined using YAML or a visual designer and consist of stages and jobs.
• Stage:
  A stage is a logical subdivision within a pipeline. It represents a phase of your software delivery process, such as build, test, or deployment to a specific environment. Stages are executed sequentially by default but can be parallelized for efficiency.
• Job:
  Each stage contains one or more jobs. A job represents a single task, which could be a build, test, or deployment task. Jobs can run on different agents or machines and can be configured to depend on the success of other jobs.
• Agent:
  An agent is a machine or virtual environment where jobs are executed. Azure Pipelines provides hosted agents in the cloud or allows you to use your self-hosted agents on your own infrastructure.
• Artifact:
  Artifacts are the files and dependencies produced during the build process. These can be published, stored, and later used in deployment stages. Artifacts ensure consistency in deployments.
• Triggers:
  Triggers determine when a pipeline should be executed. Azure Pipelines supports various triggers, including code commits, pull requests, and scheduled builds.
• Environments:
  Environments represent target deployment environments, such as development, staging, and production. They allow for more granular control over deployment approvals and can be integrated with Azure Resource Manager templates for infrastructure provisioning.
• Variables and Parameters:
  These allow you to define and manage configuration settings for your pipelines, making them more flexible and reusable.

Create Your First Azure DevOps Pipeline

To initiate the process of creating your initial Python pipeline, commence by forking the designated repository into your GitHub account. Once accomplished, navigate to your Azure DevOps organization upon logging in.

In the next step, proceed to the Pipelines section and opt for the creation of a new pipeline. As your source code repository, select GitHub and diligently adhere to the instructions provided by the wizard. This may involve redirection to GitHub, where you will be prompted to log in with your GitHub credentials. Subsequently, select your repository from the list available.

To facilitate the installation of the Azure Pipelines application, you might be redirected to GitHub once more. In this instance, opt for "Approve & Install" to grant the system permission to install Azure Pipelines. Azure Pipelines will then inspect your repository and make an automatic recommendation of the Python package pipeline template.

When the new pipeline materializes, meticulously examine the accompanying YAML to understand its functionality. Once satisfied, save your settings and initiate the pipeline run. You may encounter a prompt instructing you to add a new azure-pipelines.yml file to your repository. Follow this guidance and save the changes before reattempting the run.

To observe your pipeline in action, navigate to the build job section. The YAML pipeline (azure-pipelines.yml) in your repository is now operational and can be customized as per your project's requirements. For future modifications, locate your pipeline on the Pipelines page and access the azure-pipelines.yml file using an editor.
