YAML pipeline editor

Azure Pipelines provides a YAML pipeline editor based on the Monaco Editor that you can use to author and edit your pipelines from the Azure DevOps portal. The editor provides tools like Intellisense support and a task assistant to provide guidance when editing a pipeline.

Important

The YAML pipeline editor was introduced in Azure DevOps Server 2019 Update 1. If you are using Azure DevOps Server 2019 RTW, the YAML pipeline editor described in this article is not available, but you can edit your YAML using the text editor of your choice and check it into your pipeline's repository.

View and edit templates

Templates are a commonly used feature in YAML pipelines. They are an easy way to share pipeline snippets. They are also a powerful mechanism in verifying or enforcing security and governance through your pipeline.

Azure Pipelines supports a YAML editor which can be handy when editing your pipeline. Previously, the editor did not support templates. Authors of YAML pipelines could not get intellisense assistance when using a template. With this release, we are previewing support for templates in the YAML editor. To enable this preview, navigate to preview features in your Azure DevOps organization, and enable YAML templates editor.

As you edit your main Azure Pipelines YAML file, you can either include or extend a template. As you type in the name of your template, you may be prompted to validate your template. Once validated, the YAML editor understands the schema of the template including the input parameters.

Post validation, you can navigate into the template by choosing View template, which opens the template in a new browser tab. You will be able to make changes to the template using all the features of the YAML editor.

Important

This feature is in preview. There are known limitations. If the template has required parameters that are not provided as inputs in the main YAML file, then the validation fails and prompts you to provide those inputs. In addition, you cannot create a new template from the editor. You can only use or edit existing templates.
