| # Indempotent VM spawning config | ||
|
|
||
|
|
||
|
|
||
| ## Core concepts: | ||
|
|
||
| - Fully reproducible and sharable cfengine testing environment | ||
| - Should work for dev environment: support for package install and scripts | ||
| - Atomic config: either all vms created or none. No in-between states. | ||
| - Top-down run order | ||

There was a problem hiding this comment. Not sure what you mean by these 2 points. |
||
| - VMs bound to config that generated them. Should not manually interfer: VMs should not be destroyed manually and the config should not be modified while VMs are running. | ||

There was a problem hiding this comment. I think it's desirable if you can edit the config and re-run cf-remote. It should detect what is missing and fix it (repair it). This is useful to for example add one more client. |
||
| - Should provide abstraction of provider (aws, vagrant, static) | ||
|
|

|
|
||
| ## Example: | ||
|
|
||
| ``` | ||
| machines: | ||

There was a problem hiding this comment. I think we should work a bit more on this part. I don't like the name (machines) and I don't like that it mixes some quite different things. For AWS and vagrant it specifies how / what to spawn (spawn config), while in static there is just a list of hosts. |
||
| - ubuntu-vm: | ||
| provider: aws # if we want to force provider | ||
| count: 1 # ignore if provider is "static" | ||

There was a problem hiding this comment. Static means managing pre-existing machines with SSH? |
||
|
|
||
| packages: | ||
| - cfengine-master: | ||
| package: cfengine | ||
| version: master | ||
| bootstrap: myhub # myhub count must be 1 | ||
|
|
||
| - git-latest: | ||
| package: git | ||
| version: latest | ||
|
|
||
|
|
||
| hubs: | ||
| - myhub: | ||
| from: ubuntu-vm | ||
| install: [ cfengine-master, git-latest ] | ||
| scripts: [ ./provision.sh ] | ||
|
|
||
| clients: | ||
| - myclient: | ||
| from: ubuntu-vm | ||
| install: [ cfengine-master ] | ||
| ``` | ||
