common()

This is where we override any of the common.yaml settings per environment. EG, the exec: parameter and so on. Also can be used for things like network service connection strings (e.g. Zookeeper
) and so on.

This is where any post-initialisation logic happens (connecting to a database etc.)

target_values(_template_name)

This should provide a hash similar to this example : {
'target' => "/tmp/#{template_name}", 'user' => 'root', 'group' => 'root', 'perms' => '0644', 'exec_on_write' => [ "/usr/bin/touch" , "somefile.tmp" ]
} Again, we should always return a hash; if we have no data for the given template, just return an empty hash.
# File lib/tiller/datasource.rb, line 50 def target_values(_template_name) {} end
values(_template_name)

We should always return a hash; if we have no data for the given template, just return an empty hash.
