mkdocs-pipeline-visualizer

Introduction

The mkdocs-pipeline-visualizer plugin automates the creation of up-to-date documentation for your Tekton pipelines and tasks.

Installation

To install the mkdocs-pipeline-visualizer plugin, run the following command:

$ pip install mkdocs-pipeline-visualizer

Example Configuration

Below is an example of how to configure mkdocs.yaml:

site_name: Tekton
docs_dir: ./tekton

nav:
  - Home: index.md

plugins:
  - pipeline-visualizer

markdown_extensions:
  plantuml_markdown:
    server: http://www.plantuml.com/plantuml

theme:
  name: material
  features:
    - navigation.sections

Configuration

By default, the plugin creates two sections at the root level: Pipelines and Tasks. The docs_dir should point to the location of pipelines and tasks manifests.

Example for nav_pipeline_grouping_offset

Let's say you have a pipeline file located at:

./pipelines/project-a/deployment/my-pipeline.yaml

Here's how different nav_pipeline_grouping_offset values would affect the navigation structure:

• "0:-1": Includes all directories except the last one (which is the file name).

  • Result: Pipelines > pipelines > project-a > deployment > my-pipeline

• "1:-1": Skips the first directory and includes all others except the last one.

  • Result: Pipelines > project-a > deployment > my-pipeline

• "1:-2": Skips the first directory and excludes the last two (the last directory and the file name).

  • Result: Pipelines > project-a > my-pipeline

• None (default): All pipelines are placed directly under the nav_section_pipelines section.

  • Result: Pipelines > my-pipeline

How To

Customizing Documentation Locations

You can change the location of the documentation sections by placing an empty section in any location of the navigation (nav) and setting it to the value of nav_section_pipelines or nav_section_tasks:

site_name: Tekton
docs_dir: ./tekton

nav:
  - Home: index.md
  - Tekton:
    - "Tasks": []
    - "Pipelines": []
    - "StepActions": []

plugins:
  - pipeline-visualizer

Customizing Menu Section Names and Graph Themes

To change the names of the menu sections and apply a custom graph theme, use the following configuration:

site_name: Tekton
docs_dir: ./tekton

nav:
  - Home: index.md  
  - Tekton:
    - "🛠️ Tasks": []
    - "🚀 Pipelines": []
    - "⚙️ StepActions": []

plugins:
  - pipeline-visualizer:
      plantuml_theme: hacker
      nav_section_tasks: "🛠️ Tasks"
      nav_section_pipelines: "🚀 Pipelines"
      nav_section_stepactions: "⚙️ StepActions"      

Category Name Mapping

You can customize how task categories appear in the navigation by providing mappings in the nav_category_mapping configuration:

plugins:
  - pipeline-visualizer:
      nav_category_mapping:
        "Code Quality": "Quality Tools"
        "Build": "Build Tools"
        "Deploy": "Deployment"
