I tried both epp and erb templates.
This is the manifest file:
class site::profiles::ntp {
$ntp = hiera_hash('ntp')
case $::operatingsystem {
'freebsd': {
file { "/etc/ntp.conf":
ensure => file,
recurse => true,
purge => true,
force => true,
owner => "root",
group => 0,
mode => "0644",
content => template('site/ntp/ntp.conf.epp'),
#content => template('site/ntp/ntp.conf.erb'),
}
service { 'ntpd':
ensure => 'running',
enable => true,
}
service { 'ntpdate':
enable => true,
}
}
default: {
class { 'ntp':
servers => $ntp['servers'],
}
}
}
}
The template:
templates/ntp/ntp.conf.epp
<% @ntp[’servers’].each { |server| -%>
server: <%= server %>
<% } -%>
And this is the hiera (as of now there is only one ntp server but there'll
be more in the future):
ntp:
servers:
- 169.254.169.123
Martin with the latest change I'm getting:
