A command line tool to create a graph representing your Ansible playbook tasks and roles
Ansible Playbook Grapher
ansible-playbook-grapher is a command line tool to create a graph representing your Ansible playbook tasks and roles. The aim of this project is to quickly have an overview of your playbook.
Inspired by Ansible Inventory Grapher.
- Python 3
- Ansible >= 2.8: If you still use an older version of Ansible, create a virtual environment and install ansible-playbook-grapher. pip will install a version of Ansible >= 2.8 if not already installed. I try to respect Red Hat Ansible Engine Life Cycle for the supported Ansible version.
- Graphviz: The tool used to generate the graph in SVG.
$ sudo apt-get install graphviz # or yum install or brew install
$ pip install ansible-playbook-grapher
$ ansible-playbook-grapher tests/fixtures/example.yml
$ ansible-playbook-grapher --include-role-tasks tests/fixtures/with_roles.yml
Some options are available:
$ ansible-playbook-grapher --help usage: ansible-playbook-grapher [-h] [-v] [-i INVENTORY] [--include-role-tasks] [-s] [-o OUTPUT_FILENAME] [--version] [-t TAGS] [--skip-tags SKIP_TAGS] [--vault-id VAULT_IDS] [--ask-vault-pass | --vault-password-file VAULT_PASSWORD_FILES] [-e EXTRA_VARS] playbook Make graphs from your Ansible Playbooks. positional arguments: playbook Playbook to graph optional arguments: --ask-vault-pass ask for vault password --include-role-tasks Include the tasks of the role in the graph. --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 password file --version show program's version number and exit -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, --ouput-file-name OUTPUT_FILENAME Output filename without the '.svg' extension. Default: <playbook>.svg -s, --save-dot-file Save the dot file used to generate the graph. -t TAGS, --tags TAGS only run plays and tasks tagged with these values -v, --verbose verbose mode (-vvv for more, -vvvv to enable connection debugging)
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.
TAGS_SKIP or vault configuration.

To setup a new development environment :
- Install graphviz
sudo apt-get install graphviz # or yum install or brew install graphviz
- (cd tests && pip install -r requirements_tests.txt)
Run the tests with:
$ make test # run all tests
The graphs are generated in the folder
tests/generated_svg. They are also generated as artefacts in Github Actions. Feel free to look at them when submitting PRs.
- Graphviz : properly rank the edge of the graph to represent the order of the execution of the tasks and roles
- Graphviz : find a way to avoid or reduce edges overlapping
