How do I leverage pipeline as code in
Automation Pipelines

As a DevOps administrator or developer, you might want to create a pipeline in
Automation Pipelines
 by using YAML code, instead of using the user interface. When you create pipelines as code, you can use any editor and insert comments in the pipeline code.
  • Verify that you have a code editor.
  • If you plan to store your pipeline code in a source control repository, verify that you can access a working instance.
In your pipeline code, you can refer to external configurations such as environment variables and security credentials. When you update variables that you use in your pipeline code, you can update them without having to update the pipeline code.
You can use the pipeline YAML code as a template to clone and create other pipelines, and share the templates with others.
You can store your pipeline code templates in a source control repository, which versions them and tracks updates. By using a source control system, you can easily back up your pipeline code, and restore it if needed.
  1. In your code editor, create a file.
  2. Copy and paste the sample pipeline code, and update it to reflect your specific pipeline needs.
  3. To include an endpoint to your pipeline code, copy and paste the example endpoint code, and update it to reflect your endpoint.
    When using a Kubernetes API endpoint in the pipeline workspace,
    Automation Pipelines
     creates the necessary Kubernetes resources such as ConfigMap, Secret, and Pod to run the continuous integration (CI) task or custom task.
    Automation Pipelines
     communicates with the container by using the NodePort.
    The
    Automation Pipelines
     pipeline workspace supports Docker and Kubernetes for continuous integration tasks and custom tasks.
    For more information about configuring the workspace, see Configuring the Pipeline Workspace.
  4. Save the code.
  5. To store and version your pipeline code, check the code into your source control repository.
  6. When you create a continuous integration and delivery pipeline, you must import the Kubernetes YAML file.
    To import the Kubernetes YAML file, select it in the Continuous Delivery area of the smart pipeline template, and click
    Process
    . Or, use the API.
By using the code examples, you created the YAML code that represents your pipeline and endpoints.
Example YAML code for a pipeline and endpoints
This example YAML code includes sections that represent the workspace for the
Automation Pipelines
 native build, stages, tasks, notifications, and more in a pipeline.
