[chef] Re: Re: Dynamically Creating Configuration file

[Sachin Gupta < >]

Hi,

I have modified my role file and added some location instance attribute, so that I can iterate through a loop in the mod_wl_ohs template now my role file is

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


added this code in mod_wl_ohs template to generate mod_wl_ohs.conf file

<IfModule weblogic_module>
        <% node[:oc_ohs][:locations].each do |location, location_attrib| %>
       #<%= location %>
      <Location <%= location_attrib.path %>>
       SetHandler <%=location_attrib.set_handler %>
       Debug <%=location_attrib.debug %>
       <% if location_attrib.weblogic_host != "" -%>
       WeblogicHost <%=location_attrib.weblogic_host %>
       <% end -%>
       <% if location_attrib.weblogic_port != "" -%>
       WeblogicPort <%=location_attrib.weblogic_port %>
       <% end -%>
        <% if location_attrib.weblogic_cluster != "" -%>
        WebLogicCluster <%=location_attrib.weblogic_cluster %>
       <% end -%>
        <% if location_attrib.wl_proxy_ssl_pass_through != "" -%>
        WLProxySSLPassThrough <%=location_attrib.wl_proxy_ssl_pass_through %>
       <% end -%>
        <% if location_attrib.wl_proxy_ssl != "" -%>
        WLProxySSL <%=location_attrib.wl_proxy_ssl %>
       <% end -%>
       WLLogFile "${ORACLE_INSTANCE}/diagnostics/logs/OHS/${COMPONENT_NAME}/ohs_WLScomponent.log"
       </Location>


       <% end %>
</IfModule>

In my install ohs recipe, generated the mod_wl_ohs.conf file through a template

##Configure mod_wl_ohs.conf file from template
  template "#{node[:oc_fmw][:ohs_configFile_path]}/mod_wl_ohs.conf" do
  source 'mod_wl_ohs.conf.erb'
  owner node[:oc_ohs][:user]
  group node[:oc_ohs][:group]
  mode '0644'
  end

also added the check's in the mod_wl_ohs.conf.erb template, if any value is null then it will not write to mod_wl_ohs.conf file. also able to restart the ohs instance will generated mod_wl_ohs.conf file.  Now this is working fine as expected.

Thanks & Regards,

Sachin Kumar

Well for starters I'd try accessing the attribute as an attribute instead of a method

#{location_attrib['path']}

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,
Sachin Gupta
