$ gem install cloudconfig

Usage

Cloudconfig will configure resources in Cloudstack.

cloudconfig --help

Create config:

cloudconfig config URL API_KEY SECRET_KEY RESOURCE_DIRECTORY

Dryrun can be performed to view potential changes:

cloudconfig update hosts --dryrun

Configuration of resources

Cloudconfig will configure resources in Cloudstack according to resources in yaml files in specified directory.

Resources that currently are handled by cloudconfig:

Compute offerings (create, update, delete)
Disk offerings (create, update, delete)
System offerings (create, update, delete)
Host tags (create, delete)
Storage tags (create, delete)

Resource files are expected to be structured in following manner in configured resource directory:
