Creating stacks with client/server in it:
Creating a parameter file
The easiest way to create a stack needing parameters is to create a parameter-file. Based on the output of the first heat-stack, and from retrieving ID's using commands like "openstack flavor list" and "openstack image list" we can create a parameter-file like so:
| Code Block |

| language | yml |

| linenumbers | true |

| collapse | true |

parameters:

network: db265ea1-1d85-47f1-ba3a-714174da114e |
Creating a stack with parameters using the CLI
To create a stack using the CLI you use the openstack stack create command:

At this point there is created two VM's with the floating IP's 10.212.25.246 and 10.212.26.229. Afther they have booted, gotten their updates installed, and being rebooted, they are ready to use. You can then log into them using the username "admin" or "user" if you have the correct SSH private keys. You can also see the servers using the regular openstack commands:
