Chef: Undefined node attribute or method `<<' on `node' when trying to add

Question

In my attributes file for postgresql recipe I have:

default[\'postgresql\'][\'pg_hba\'] = {
    :comment => \'# IPv4 lo         


        

Answer 1

Your problem is here:

node['postgresql']['pg_hba'] << {

This way you're accessing the attribute for reading.

Assuming you want to stay at default level you have to use default method like this:

node.default['postgresql']['pg_hba'] << { ... }

This will call default method (like in attribute file) to add the entry.

For this to work the first attribute declaration should be an array (or a hash of hash) like this:

default['postgresql']['pg_hba'] = [{ # notice the [ opening an array
    :comment => '# IPv4 local connections',
    :type => 'host',
    :db => 'all',
    :user => 'all',
    :addr => '127.0.0.1/32',
    :method => 'md5'
}] # Same here to close the array
