usage: task_graph.py [-h] [--workbook] [--clear_workbook] [--dot] [--png]
[--png_file PNG_FILE] [--debug] [--group GROUP]
[--topology]
FILE [FILE ...]
positional arguments:
FILE The list of files of directories where tasks can be
found
optional arguments:
-h, --help show this help message and exit
--workbook, -w Output the raw workbook
--clear_workbook, -c Output the clear workbook
--dot, -D Output the graph in dot format
--png, -p Write the graph in png format (default)
--open, -o Open the image after creation
--png_file PNG_FILE, -f PNG_FILE
Write graph image to this file
--debug, -d Print debug messages
--group GROUP, -g GROUP
Group or stage to build the graph for
--topology, -t Show the tasks topology (possible execution order)
This tools can be used to create a task graph image. Just pouint it
at the folder where tasks.yaml files can be found.
> utils/task_graph/task_graph.py deployment/puppet/osnailyfacter/modular
It will create task_graph.png file in the current directroy.
You can also use -w and -c options to inspect the workbook yamls
files and output graph as graphviz file with -o option.
You can filter graph by roles and stages with -g option like this
> utils/task_graph/task_graph.py -g post_deployment deployment/puppet/osnailyfacter/modular
And you can use -t option to view the possible order of task execution
with the current graph.
> utils/task_graph/task_graph.py -t deployment/puppet/osnailyfacter/modular
