Managing Stacks

Orchestration provides a level of automation in creating your virtual machines through templates. Use the orchestration engine to create and manage your infrastructure resources through a single or set of YAML files. For example, you can define storage, networking, instances, and applications and use that template repeatedly to create a running environment instead of defining these values each time.

Templates are used to create stacks, which are collections of resources. For example, a stack might include instances, floating IPs, volumes, security groups, and users. The Orchestration service offers access to all Metcloud core services through 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, see the Launching and Managing Stacks.

Note
The heat Command-line Interface is deprecated in favor of python-openstackclient. For a Python library, continue using python-heatclient.

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 the openstack stack commands:

$ openstack stack resume STACK
$ openstack stack suspend STACK
$ openstack stack delete STACK
