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 playbook.
Inspired by Ansible Inventory Grapher.
The following features are available when opening the SVGs in a browser (recommended) or a viewer that supports JavaScript:
- Highlighting of all the related nodes of a given node when clicking or hovering. Example: Click on a role to select
all its tasks when
--include-role-tasksis set. - A double click on a node opens the corresponding file or folder depending whether if it's a playbook, a play, a task
or a role. By default, the browser will open folders and download files since it may not be able to render the YAML
file.
Optionally, you can set the open protocol to use VSCode with--open-protocol-handler vscode: it will open the folders when double-clicking on roles (notinclude_role) and the files for the others nodes. The cursor will be at the task exact position in the file.
Lastly, you can provide your own protocol formats with--open-protocol-handler custom --open-protocol-custom-formats '{}'. See the help and an example. - Filer tasks based on tags
- Export the dot file used to generate the graph with Graphviz.
- Python 3.10 at least. Might work with some previous versions but the code is NOT tested against them. See support matrix.
- A virtual environment from which to run the grapher. This is highly recommended because the grapher depends on
some versions of ansible-core which are not necessarily installed in your environment and may cause issues if you use
some older versions of Ansible (
since
ansiblepackage has been split). - Graphviz: The tool used to generate the graph in SVG.
sudo apt-get install graphviz # or yum install or brew install
I try to respect Red Hat Ansible Engine Life Cycle for the supported Ansible version.
pip install ansible-playbook-grapherYou can also install the unpublished version from GitHub direction.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"At the time of writing, two renderers are supported:
graphviz(default): Generate the graph in SVG. It has more features and is more tested: open protocol, highlight linked nodes...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. Early support.
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 blocks are 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.

[-e EXTRA_VARS]
playbooks [playbooks ...]
Make graphs from your Ansible Playbooks.
positional arguments:
playbooks Playbook(s) to graph
options:
--ask-vault-password, --ask-vault-pass
ask for vault password
--group-roles-by-name
When rendering the graph, only a single role will be
display for all roles having the same names. Default:
False
--include-role-tasks Include the tasks of the role in the graph.
--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. 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}
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
--vault-id VAULT_IDS the vault identity to use
--vault-password-file VAULT_PASSWORD_FILES, --vault-pass-file VAULT_PASSWORD_FILES
vault password file
--version show program's version number and exit
--view Automatically open the resulting SVG file with your
system’s default viewer application for the file type
-e EXTRA_VARS, --extra-vars EXTRA_VARS
set additional variables as key=value or YAML/JSON, if
filename prepend with @
-h, --help show this help message and exit
-i INVENTORY, --inventory INVENTORY
specify inventory host path or comma separated host
list.
-o OUTPUT_FILENAME, --output-file-name OUTPUT_FILENAME
Output filename without the '.svg' extension. Default:
<playbook>.svg
-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
-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.
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.
More information here.
- Since Ansible Playbook Grapher is a static analyzer that parses your playbook, it's limited to what can be determined
statically: no task is run against your inventory. The parser tries to interpolate the variables, but some of them are
only available when running your playbook (
ansible_os_family, ansible_system, etc.). The tasks inside any
import_*orinclude_*with some variables in their arguments may not appear in the graph. - The rendered SVG graph may sometime display tasks in a wrong order. I cannot control this behavior of Graphviz yet. Always check the edge label to know the tasks order.
- The label of the edges may overlap with each other. They are positioned so that they are as close as possible to the target nodes. If the same role is used in multiple plays or playbooks, the labels can overlap.
Contributions are welcome. Feel free to contribute by creating an issue or submitting a PR 😃
To setup a new development environment :
- Install graphviz (see above)
- (cd tests && pip install -r requirements_tests.txt)
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 testsThe 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.
The project uses black to format the code. Run black . to format.
