Abstract

Aspects extend to methods, systems, and computer program products for using declarative configuration data to resolve errors in cloud operation. A tool (e.g., a maintenance module) and a design model can be used for bootstrapping a cloud stack that enables an external media based deployment model. The deployment model allows provisioning of an entire cloud stack as well as reset of or recovery from a failure of an existing cloud deployment instance. In one aspect, a bootstrap command for a cloud, a recovery command for the cloud, and a reset command for the cloud are consolidated within declarative configuration data. The tool (e.g., the maintenance module) can refer to the declarative configuration data to implement any of the bootstrap command, the recovery command, or the reset command.
