A knife plugin that creates a graph out of various Chef resources.
Currently the only supported output is the mapping from roles to other roles and recipes (run_list).
- graphviz
- Box: Role
- Ellipse: Recipe
Only one knife subcommand is supported. More will probably be added later, to support different resource mappings.
This plugin uses graphviz's dot to render the graph to jpg. Running the following command will create the file knife-graph.jpg with the exported data.
knife graph # => knife-graph.jpg
A few options are available:
If environment is set (-E|--environment), the plugin will use the environment specific run_list if exists. i.e. the same resolving Chef does when executing a run_list.
Sets the output filename (and type according to the extension, supported types)
If the .dot extension is used, no rendering is performed. With .dot you could use the file, to make custom manipulations
or render it using your favorite tool. Use a dash (-) to set output to STDOUT.
If STDOUT output is used, this option sets the type. Otherwise, ignored. (Default is jpg)
knife graph -E production # => knife-graph.jpg using environment run_list of production if available
knife graph -O knife-graph.bmp # => knife-graph.bmp
knife graph -O knife-graph.dot # => knife-graph.dot
knife graph -O- -tjpg > my-chef-installation.jpg # => JPG output to STDOUT
