[chef] Re: Can chef parse the attribute list and handle it while creating templates

[Faiz Kazi < >]

If your attribute value is actually a list:

default['zabbix']['agent']['servers_active'] = [ "hostname1", "hostname2" ]

Then in your template, you could just render it's elements separated by a 
comma:

ServerActive=<%= node.zabbix.agent.servers_active.join(",") %>


If you want to have it both ways - perhaps you have some legacy roles that
still insist on single values and not lists:

# just a single value, not passed as a list
default['zabbix']['agent']['servers_active'] = "hostname"

# several values passed as a list
default['zabbix']['agent']['servers_active'] = [ "hostname1", "hostname2" ]


Then in your template, to treat whatever is passed as a list:

ServerActive=<%= [node.zabbix.agent.servers_active].join(",") %>


HTH.
