[chef] Re: Re: RE: how to append an variable using chef

[Sachin Gupta < >]

Hi Daniel/Chris,

I followed a simple approach to define an array and pushing the values in appropriate format in that array and then finally setting the attribute through an arrray like 

wls_servers = Array.new

 node[:oci_ohs][:wls_cluster].each do |cluster, cluster_attrib|
        cluster_attrib.managed_servers.each do |managed_server, man_attrib|
        Chef::Log.info "the IP address  is #{man_attrib.ip_address} and port is #{man_attrib.listen_port}"
         wls_servers << "#{man_attrib.ip_address}:#{man_attrib.listen_port}"
        end
        end

 node.set[:oci_ohs][:wls_cluster_detail] = wls_servers.join(",")
  Chef::Log.info "the WLS Cluster Information  are #{node[:oci_ohs][:wls_cluster_detail]}"

Now I am able to get the weblogic cluster information like, I need this information to define in mod_wl_ohs.conf
WebLogicCluster 10.152.173.31:7101,10.152.173.31:7101,10.152.173.31:7101 

Thanks

Sachin

It’s always better to manage the whole resource if you can. If you generated that file from a template earlier, it would be preferable to merge the data you pass in to the template instead of appending to it like this.

If you have no other option, then you should take care to ensure that this won’t keep appending every time you run chef.
