Key Components of an Azure Pipeline
Pipeline Definition
The pipeline definition is the blueprint of your CI/CD process. You can define it using YAML files, which provide a code-as-configuration approach, or through Azure DevOps' visual designer.
Triggers
Triggers define when your pipeline should be executed. Common triggers include code commits, pull requests, and scheduled runs.
Stages
Stages represent different phases of your CI/CD pipeline, such as build, test, and deploy. Each stage can contain multiple jobs and tasks.
Jobs
Jobs are units of work executed within a stage. Each job runs on an agent and can include tasks like running scripts, compiling code, or deploying applications.
Steps
Steps are individual actions within a job, such as checking out code from a repository, installing dependencies, or running tests.
Agents
Agents are the execution environments where your pipeline jobs run. Azure Pipeline supports both Microsoft-hosted agents (managed by Azure) and self-hosted agents (managed by you).
Artifacts
Artifacts are the outputs of your build process, such as compiled binaries, packages, or configuration files. These artifacts can be stored and used in subsequent stages.
Variables
Variables store dynamic values that can be used across your pipeline. They are useful for configuration settings, secrets, and other data that may change between runs.
Environment
Environments represent the target deployment locations for your applications, such as development, staging, and production environments.
Approvals and Gates
Approvals and gates allow you to implement manual checks or automated criteria that must be met before a deployment can proceed.
Notifications
Azure Pipeline supports notifications through email, Slack, and other tools, keeping your team informed about the status of pipeline runs.
Logs and Monitoring
Detailed logs are generated for each pipeline run, helping you monitor progress and troubleshoot any issues that arise.
