Generate a graph of Ansible role dependencies.
pip install ansible-roles-graph
Assuming you already installed graphviz with python bindings.
Quite simply:
ansible-roles-graph
Will look for roles in the ./roles/
directory, and generate an ./ansible-roles.png
file.
The command also accepts multiple role directories and various options:
ansible-roles-graph -o schema.png -f png roles/ ../other/roles
See ansible-roles-graph --help
for more info.
