YAML pipeline editor

Azure DevOps Services | Azure DevOps Server 2022 - Azure DevOps Server 2019

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

Important

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

To access the YAML pipeline editor, do the following steps.

  1. Sign in to your organization (https://dev.azure.com/{yourorganization}).

  2. Select your project, choose Pipelines > Pipelines, and then select the pipeline you want to edit.

View and edit templates

Templates are a commonly used feature in YAML pipelines. They're an easy way to share pipeline snippets and are a powerful mechanism for verifying and enforcing security and governance in your pipeline. Previously, the editor didn't support templates, so authors of YAML pipelines couldn't get intellisense assistance. Now Azure Pipelines supports a YAML editor, for which we're previewing support. To enable this preview, go to preview features in your Azure DevOps organization, and enable YAML templates editor.

Important

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

As you edit your main Azure Pipelines YAML file, you can either include or extend a template. As you enter 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 go into the template by choosing View template, which opens the template in a new browser tab. You can make changes to the template using all the features of the YAML editor.
