====================================== Launch and manage stacks using the CLI ====================================== The Orchestration service provides a template-based orchestration engine for the OpenStack cloud, which can be used to create and manage cloud infrastructure resources such as storage, networking, instances, and applications as a repeatable running environment. Templates are used to create stacks, which are collections of resources. For example, a stack might include instances, floating IPs, volumes, security groups, or users. The Orchestration service offers access to all OpenStack core services via a single modular template, with additional orchestration capabilities such as auto-scaling and basic high availability. For information about: - basic creation and deletion of Orchestration stacks, refer to the `OpenStack End User Guide `_ - **heat** CLI commands, see the `OpenStack Command Line Interface Reference `_ As an administrator, you can also carry out stack functions on behalf of your users. For example, to resume, suspend, or delete a stack, run: .. code-block:: console $ heat action-resume stackID $ heat action-suspend stackID $ heat stack-delete stackID
