kapitan-docs

kapitan-docs is a tool to automatically generate documentation for a Kapitan project.

The markdown generation is managed by go text/template package. kapitan-docs parses metadata from a Kapitan project and generates a number of sub-templates that can be referenced in a template file (by default README.md.gotmpl). If no template file is provided, the tool has a default internal template that will generate a reasonably formatted README.

Currently only class documentation is supported !

The most useful aspect of this tool is the auto-detection of field descriptions from comments, e.g for a class ./foo/bar.yaml:

# -- Foo is a test class, used to display an example.
#
# Class comment support **markdown** in comments.

classes:
  - bar.baz

parameters:
  foo:
    # -- A `number`
    number: 2
    # -- A `string`
    string: "foo"
    # -- An `object`
    object:
      bar: baz
    # -- A `list`
    list:
      - myvalue1
      - myvalue2
      - myvalue3

Resulting in a resulting README section like so:

foo.bar

Foo is a test class, used to display an example.

Class comment support markdown in comments.
