In this article we will see what are the different components of Azure Devops Pipelines.
These components are there basic foundation of Azure Devops Pipelines, understanding these plays a key role while working on Azure Devops.
Trigger : As the name suggests it will start the Pipeline execution. Trigger can start a pipeline as per schedule or if any activity happens. In short, when the pipeline should run is defined in a trigger.
Stages : It is the logical separation between different environments like we can a stage for Dev environment, one for QA and so on. A pipeline can have single or multiple stages. By default the stages will run one after another, we can also specify conditions when a stage to run.
Job : A job is collection of single or multiple steps. It is the smallest unit in a pipeline which can be scheduled. Each Stage in a Azure Pipeline will have single or multiple Jobs. Every pipeline will have at least one job.
Job Agent : To build or deploy code we need at least one job agent. Job agent acts as a compute infrastructure for the jobs to run. Note: Few jobs can run without agent also.
Step : Step is the smallest building block of a Azure Pipeline. Each job step will have details of the actual action that needs to be done. Each job will have single or multiple Steps.
Task : A task can be a script or procedure to perform certain action. Action can be building an application, deploy IoT image, push docket images and so on. There are many built-In tasks and custom tasks can be created as well.
