[chef] Dynamically Creating Configuration file

[Sachin Gupta < >]

Hi All,

I am writing OHS cookbooks for my project and created a role file as,

 "locations": {
                "Gateway": {
                    "path": "/p1",
                    "weblogic_host": "somefqdn1.com",
                    "weblogic_port": "8001",
                    "set_handler": "weblogic-handler"
                },
                "Analytics": {
                    "path": "/p2",
                    "weblogic_cluster": "somefqdn2.com:8101,somefqdn3.com:8101",
                    "set_handler": "weblogic-handler",
                    "wl_proxy_ssl_pass_through": "ON",
                    "wl_proxy_ssl": "ON"
                }
            }


with these attribute values, I would like to populate my mod_wl_ohs.conf something like this


#Gateway
<path /p1>
SetHandler weblogic-handler
weblogic_host somefqdn1.com
weblogic_port 8001
</Location>

#Analytics
<path /p2>
SetHandler weblogic-handler
weblogic_cluster somefqdn2.com:8001,somefqdn3.com:8001
wl_proxy_ssl_pass_through ON
wl_proxy_ssl ON
</Location>

#    Compress ouput from server before being sent to client side network
#    DeflateBufferSize 20000

</IfModule>


In my OHS install recipe, I have added the code to iterate over locations as

      node[:oc_ohs][:locations].each do |location, location_attrib|
        Chef::Log.info "the different locations are #{location}"
        Chef::Log.info "the app path is   is #{location_attrib.path}"
       end

I am able to get two locations as Gateway and Analytics and there paths as /p1 and p2 respectively.
but when I tried to get attributes values for weblogic_host and weblogic_port, getting error as

[2015-06-17T07:53:01+00:00] ERROR: Undefined method or attribute `weblogic_host' on `node'

this may be because weblogic_host and weblogic_port are not defined in second location Analytics

so how to get different attribute values of location instances. and how to dynamically create mod_wl_ohs.conf from these attribute values.

Any idea would be helpful.


Thanks & Regards,
