simple-cdd-yaml 0.1.0

YAML recipe interpreter for Simple-CDD

Simple-CDD-YAML

Preprocesser for Simple-CDD using YAML input files (so-called recipes), as inspired by debos.

Introduction

Simple-CDD-YAML uses YAML recipes to generate the profile files required by Simple-CDD. A recipe consists of actions, that generate or append files in the Simple-CDD profile. Simple-CDD-YAML features the following actions:

• recipe action: embed another recipe
• conf action: compose a *.conf file by supplying (environment) variables
• preseed action: define a preseed file
• apt action: add packages
• run action: add a command or script (to *.postinst)
• overlay action: add an overlay. An overlay is a file structure that is compressed into one single file and automatically added to *.extra.
  A corresponding command to decompress the overly is added *.postinst
• extra action: add extra file
• downloads action: add extra packages
• debos action: [only in debos mode] add pre- and post-action to debos recipe output

Some of the actions support substitutions using jinja notation, making it easier to reuse scripts, preseeds and recipes. By defining variables with default values at the top of a recipe it becomes easy to reuse and nest recipes.

A few actions also support different roles: by default a script is run or an overlay is deployed as root, but you can also specify to have this done by a certain user.

Please refer to the documentation for more information.
