||||
cdist-design - Design ideas for cdist |
||||
|
||||
DESCRIPTION |
||||
----------- |
||||
|
||||
When using cdist with the push principle, the execution tree looks likes this: |
||||
|
||||
-------------------------------------------------------------------------------- |
||||
% server |
||||
cdist-deploy-to(1) # main tool for deployment |
||||
cdist-config(1) # setup environment |
||||
cdist-build(1) # coordinates build process / dummy otherwise |
||||
cdist-preprocess(1) # fills up variables with content |
||||
cdist-explore(1) % client # explores client configuration |
||||
cdist-compile(1) # parses configuration, |
||||
# creates internal state in cconfig format, |
||||
# verifies configuration |
||||
cdist-link(1) # uses cconfig output, creates executable |
||||
cdist-remote-exec(1) # coordinates remote execution, dummy otherwise |
||||
cdist-transfer(1) # transfer executable to client |
||||
cdist-execute(1) % client # execute resulting executable |
||||
-------------------------------------------------------------------------------- |
||||
|
||||
Operation on the server is run as "cdist" user. |
||||
Operation on the client is run as "root" user. |
||||
|
||||
When using cdist with the pull principle (configuration triggered by client): |
||||
|
||||
-------------------------------------------------------------------------------- |
||||
% client |
||||
cdist-trigger(1) <server-hostname> # connects to server |
||||
cdist-deploy-to(1) <client-hostname> % server: see above |
||||
-------------------------------------------------------------------------------- |
||||
|
||||
|
||||
MERGE INTO ABOVE..... |
||||
## How cdist works |
||||
|
||||
### Exploring your system |
||||
|
||||
cdist analyses the system to apply the configuration on and |
||||
selects the right backends. You can use ***cdist-explore*** to |
||||
the results of the explore functions. |
||||
|
||||
### Applying the configuration |
||||
|
||||
cdist looks for the configuration to apply on the local host |
||||
and applies it using ***cdist-apply***. |
||||
|
||||
### Managing many hosts |
||||
|
||||
Whereas ***cdist-apply*** manages one host, ***cdist-deploy*** |
||||
applies the configuration on enabled hosts. |
||||
|
||||
- version control via git |
||||
- file distribution via ssh |
||||
- authentication via ssh |
||||
|
||||
- dumb clients, similar to manifest compile in puppet |
||||
- clients just execute commands |
||||
- dependencies via make? |
||||
- how to ensure sigletons / conflicting definitions? |
||||
file { "/a": |
||||
ensure => present, |
||||
file { "/a": |
||||
ensure => absent, |
||||
=>=>>>>>>>>>>>>>>>> via cconfig |
