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:
