Hi
I am new to puppet and need to manage host entries in file /etc/hosts as
follows on node mail.example.com and db.example.com. I do not want to
manage the whole file /etc/hosts with puppet, only a few entries.
puppet version 3.2.1
node mail.example.com, file /etc/hosts:
(..)
172.16.89.96 ldapmaster.example.com ldapmaster ldap
172.16.89.85 sms.example.com sms sms-gateway
(..)
node db.example.com, file /etc/hosts:
(..)
172.16.89.80 abc.example.com abc
172.16.89.81 xyz.example.com xyz bigben
(..)
In general, a node may have 0 to n host entries. The number of host entries
on a node A may differ from the number host entries on a node B. A certain
host entry ( IP-Address Full-Qualified-Hostname Short-Hostname)
may be in the file /etc/hosts on 0 to n nodes concurrently.
To manage the above host entries on node mail.example.com and
db.example.com I used Ruby DSL as follows, then I learnt that Ruby DSL is
deprecated. What is the alternative to Ruby DSL ? Any hint
would be helpful.
A puppet module using Ruby DSL:
puppetmaster:/etc/puppet/modules/hosts/manifests # cat init.rb
hostclass :hosts do
entries = scope.lookupvar("hosts_entries")
raise Puppet::ERROR,
"hosts_entries must be a Hash" unless entries.kind_of?(Hash)
entries.each do |title, parameters|
host( title,
:ensure => parameters["ensure"],
:target => parameters["target"],
:ip => parameters["ip"],
:host_aliases => parameters["host_aliases"])
end
end
puppetmaster:/etc/puppet/modules/hosts/manifests #
Basic ENC script output for the Ruby DSL and node mail.example.com :
