What is an Environment?
I see an Environment as a container for anything that affects the behavior of the Template (kinda like structured parameters).
- So parameters can be written into an environment file or automatically inserted if you pass them on the cli.
- You define any non-default Providers in the Environment
- You can define any extra/non-keystone credentials in the Environment
- other arguments passed into the stack and stored (Timeout & rollback)
| Template | Static architectural design of your application |
| Environment | Specific details that affect the instantiation of the Template |
| Stack | Template + Environment |
Example
options:
#Parameters and other global options
InstanceType: m1.xlarge
DBUsername: angus
DBPassword: verybadpass
KeyName: heat_key
timeout: 36000
disable_rollback: True
credentials:
#note the keystone credentials will get inserted here as "keystone"
rax_angus:
username: myusername
api_key: 012345abcdef67890
resources:
# resource scoped options
DatabaseServer:
Provider: RACKSPACE
Credentials: rax_angus
WebServer:
Provider: RACKSPACE
Credentials: rax_angus
