openstack stack create
 --template myStack.yml
 --environment myStack-Env.yml
 myStack

Listing stacks

To list the running stacks, issue the following command:

openstack stack list

Deleting a running stack

To destroy a running stack named myStack, issue the following command:

openstack stack delete myStack

Listing resources in a stack

To list the resources in a running stack, issue the following command:

openstack stack resource list

To list the details of a specific resource, for example, named myResource, issue the following command:

openstack stack resource show myResource

Viewing the outputs of a running Stack

To view the outputs produced by the Stack, issue the following command:

openstack stack output list

To view the details of the specific output, carry out the following command:

openstack stack output show myOutput
