Ansible Playbook Grapher

Testing PyPI version Coverage Status

ansible-playbook-grapher is a command line tool to create a graph representing your Ansible playbook, plays, tasks and roles. The aim of this project is to have an overview of your playbooks that you can use as documentation.

Inspired by Ansible Inventory Grapher.

Features

The following features are available when opening the SVGs in a browser (recommended) or a viewer that supports JavaScript:

Prerequisites

I try to respect Red Hat Ansible Engine Life Cycle for the supported Ansible version.

Installation

pip install ansible-playbook-grapher

You can also install the unpublished version from GitHub direction. Examples:

# Install the version from the main branch
pip install "ansible-playbook-grapher @ git+https://github.com/haidaraM/ansible-playbook-grapher"

# Install the version from a specific branch
pip install "ansible-playbook-grapher @ git+https://github.com/haidaraM/ansible-playbook-grapher@specific-branch"

Renderers

At the time of writing, two renderers are supported:

  1. graphviz (default): Generate the graph in SVG. Has more features than the other renderers.
  2. mermaid-flowchart: Generate the graph in Mermaid format. You can directly embed the graph in your markdown and GitHub ( and other integrations) will render it.
  3. json: Generate a JSON representation of the graph to be used by other tools. The corresponding JSON schema is here.

If you are interested to support more renderers, feel free to create an issue or raise a PR based on the existing renderers.

Note on block: Since a block is a logical group of tasks, the conditional when is not displayed on the edges pointing to them but on the tasks inside the block. This mimics Ansible behavior regarding the blocks.

CLI options

The available options:

usage: ansible-playbook-grapher [-h] [-v] [-i INVENTORY] [--include-role-tasks] [-s] [--view] [-o OUTPUT_FILENAME] [--open-protocol-handler {default,vscode,custom}]
                                [--open-protocol-custom-formats OPEN_PROTOCOL_CUSTOM_FORMATS] [--group-roles-by-name] [--renderer {graphviz,mermaid-flowchart,json}]
                                [--renderer-mermaid-directive RENDERER_MERMAID_DIRECTIVE] [--renderer-mermaid-orientation {TD,RL,BT,RL,LR}] [--version]
                                [--hide-plays-without-roles] [--hide-empty-plays] [-t TAGS] [--skip-tags SKIP_TAGS] [--vault-id VAULT_IDS]
                                [-J | --vault-password-file VAULT_PASSWORD_FILES] [-e EXTRA_VARS]
                                playbooks [playbooks ...]

Make graphs from your Ansible Playbooks.

positional arguments:
  playbooks             Playbook(s) to graph

options:
  --group-roles-by-name
                        When rendering the graph (graphviz and mermaid), only a single role will be displayed for all roles having the same names. Default: False
  --hide-empty-plays    Hide the plays that end up with no tasks in the graph (after applying the tags filter).
  --hide-plays-without-roles
                        Hide the plays that end up with no roles in the graph (after applying the tags filter). Only roles at the play level and include_role as tasks are
                        considered (no import_role).
  --include-role-tasks  Include the tasks of the roles in the graph. Applied when parsing the playbooks.
  --open-protocol-custom-formats OPEN_PROTOCOL_CUSTOM_FORMATS
                        The custom formats to use as URLs for the nodes in the graph. Required if --open-protocol-handler is set to custom. You should provide a JSON formatted
                        string like: {"file": "", "folder": ""}. Example: If you want to open folders (roles) inside the browser and files (tasks) in vscode, set it to:
                        '{"file": "vscode://file/{path}:{line}:{column}", "folder": "{path}"}'. path: the absolute path to the file containing the the plays/tasks/roles.
                        line/column: the position of the plays/tasks/roles in the file. You can optionally add the attribute "remove_from_path" to remove some parts of the
                        path if you want relative paths.
  --open-protocol-handler {default,vscode,custom}
                        The protocol to use to open the nodes when double-clicking on them in your SVG viewer (only for graphviz). Your SVG viewer must support double-click and Javascript. The
                        supported values are 'default', 'vscode' and 'custom'. For 'default', the URL will be the path to the file or folders. When using a browser, it will
                        open or download them. For 'vscode', the folders and files will be open with VSCode. For 'custom', you need to set a custom format with --open-
                        protocol-custom-formats.
  --renderer {graphviz,mermaid-flowchart,json}
                        The renderer to use to generate the graph. Default: graphviz
  --renderer-mermaid-directive RENDERER_MERMAID_DIRECTIVE
                        The directive for the mermaid renderer. Can be used to customize the output: fonts, theme, curve etc. More info at
                        https://mermaid.js.org/config/directives.html. Default: '%%{ init: { "flowchart": { "curve": "bumpX" } } }%%'
  --renderer-mermaid-orientation {TD,RL,BT,RL,LR}
                        The orientation of the flow chart. Default: 'LR'
  --skip-tags SKIP_TAGS
                        only run plays and tasks whose tags do not match these values. This argument may be specified multiple times.
  --vault-id VAULT_IDS  the vault identity to use. This argument may be specified multiple times.
  --vault-password-file VAULT_PASSWORD_FILES, --vault-pass-file VAULT_PASSWORD_FILES
                        vault password file
  --version
  --view                Automatically open the resulting SVG file with your system’s default viewer application for the file type
  -J, --ask-vault-password, --ask-vault-pass
                        ask for vault password
  -e EXTRA_VARS, --extra-vars EXTRA_VARS
                        set additional variables as key=value or YAML/JSON, if filename prepend with @. This argument may be specified multiple times.
  -h, --help            show this help message and exit
  -i INVENTORY, --inventory INVENTORY
                        specify inventory host path or comma separated host list. This argument may be specified multiple times.
  -o OUTPUT_FILENAME, --output-file-name OUTPUT_FILENAME
                        Output filename without the '.svg' extension (for graphviz), '.mmd' for Mermaid or `.json`. The extension will be added automatically.
  -s, --save-dot-file   Save the graphviz dot file used to generate the graph.
  -t TAGS, --tags TAGS  only run plays and tasks tagged with these values. This argument may be specified multiple times.
  -v, --verbose         Causes Ansible to print more debug messages. Adding multiple -v will increase the verbosity, the builtin plugins currently evaluate up to -vvvvvv. A
                        reasonable level to start is -vvv, connection debugging might require -vvvv. This argument may be specified multiple times.

Configuration: ansible.cfg

The content of ansible.cfg is loaded automatically when running the grapher according to Ansible's behavior. The corresponding environment variables are also loaded.

The values in the config file (and their corresponding environment variables) may affect the behavior of the grapher. For example TAGS_RUN and TAGS_SKIP or vault configuration.

Contribution

Contributions are welcome. Feel free to contribute by creating an issue or submitting a PR :smiley:

Local development

To setup a new local development environment :

Run the tests and open the generated files in your system’s default viewer application:

export TEST_VIEW_GENERATED_FILE=1
make test # run all tests

The graphs are generated in the folder tests/generated-svgs. They are also generated as artefacts in GitHub Actions. Feel free to look at them when submitting PRs.

Lint and format

The project uses black to format the code. Run black . to format.
