Syntax for echoing Fqdn name inside a hash value (please help)

[Virtual_user]

Hi
i am using puppet 2.7

i want to echo  the Fqdn name in a template by using looping through the hash,

Example, in site.pp i have

$acc_sudo = $mc_servertype ? {
        'system' => [ '%APP <%= fqdn %> =/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart' ],
        'db' => [ '%DB <%= fqdn %> =/etc/init.d/oracle start'],
        'app' => ['%APP <%= fqdn %> =/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart' ],

}



and sudo.erb file i have

<% if mc_servertype == "system" %>

<% acc_sudo.each do |sudo| %><%= sudo %><% end %>

<% end %>

problem is, when its generating the sudo file, its  writing like this

%APP    <%= fqdn %>=/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart


but i want to make it like this

%APP    server1.test.co=/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart


what will be the right syntax for it in site.pp ??

please help with this.

There is no hash there.  You are using a Puppet language feature called a "selector" to assign a value to variable $acc_sudo based on the value of variable $mc_servertype.  (Which value, by the way, is in each case an array containing exactly one string.  Weird.)

 

and sudo.erb file i have

<% if mc_servertype == "system" %>

<% acc_sudo.each do |sudo| %><%= sudo %><% end %>

<% end %>

%APP    <%= fqdn %>=/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart

Of course it does.  Each element of variable acc_sudo is a string.  Your template says to insert that string into the result, not to interpret it as another template.

 

but i want to make it like this

%APP    server1.test.co=/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart

You are making it harder than it needs to be.  What you are after can be accomplished with ordinary variable interpolation:

$acc_sudo = $mc_servertype ? {
        'system' => [ "%APP ${fqdn} =/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart" ],
        'db' => [ "%DB ${fqdn} =/etc/init.d/oracle start" ],
        'app' => [ "%APP ${fqdn} =/etc/init.d/httpd start, /etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd restart" ],
}

Note there that (1) the variable interpolation is performed when the string is initialized, as opposed to when the template is processed, and (2) variables are interpolated into double-quoted strings only, not into single-quoted strings.
