A puppet device plugin that makes it easier to get facts from places ruby does not run or without writing weird puppet code.
An example could be to fetch facts from SCVMM using remote calls to powershell functions written using a non ruby programming language. This script would be called by this device and as long as the script output a JSON document that will be used as the facts for the device
Configuration is using the normal device config files and it enforce some standards for arguments you have to accept:
[script_device]
type script
url script://scvmm:[email protected]:443/scvmm/bin/scvmm_discovery.rb?timeout=100
This sets up the script_device to search the modulepath
for scvmm/bin/scvmm_discovery.rb which should be executable.
The above configuration will invoke the script using the following arguments:
scvmm_discovery.rb --username=scvmm --password=xxx --server=192.16.1.1 --port=443 --timeout=100
The username, password, server and port parts of the url are optional.
You cannot change the arguments that will be passed for these standard
arguments like user, password etc but from the example above you can
see you can pass any arbitrary arguments to the script using query
parameters, they will always be invoked with --argument
the password will be decrypted using the standard ASM encryption methods
PuppetDB now supports structured facts but we are not yet running that
version of PuppetDB or Puppet. At the moment when this device type
detects that it got non Fixnum or String facts it will JSON encode the
data and store it as a string in a fact called json_facts, without
this the data gets corrupted.
