[Puppet Users] Loop with two variables in puppet

Hi,
I am stuck on this task. I need to generate a file with this content:
...
/bin/mount --bind /home/some/path/ /home/someuser/www
/bin/mount --bind /home/comple/tely/different/path/ /home/differentuser/www
/bin/mount --bind /home/another/path/ /home/anotheruser/www
.
.
...

For each row I need to insert two variables.

I am able to construct simple loop in erb file, but this does not solve my 
problem:

<% userss.each do |user| -%>
        /bin/mount --bind /some/path/<%= user %> /home/somepath/<%=
user %>
<% end -%>

I need loop, whose content looks like this:

/bin/mount --bind /some/path/<%= path %> /home/somepath/<%= user %>

Can someone point me in right direction?

Thanks.

[Puppet Users] Re: Loop with two variables in puppet

Is @path supposed to be the same for each user? If so, you can just put 
that variable in the block.
<% @users.each do |user| %>
    /bin/mount --bind <%= @path %> /home/<%= user %>
<% end %>

If each user has a path value unique to them, you might want to put that in 
an array of hashes and then iterate over that like this:

(in Puppet class)
$users = [ { name => ''alice'', path =>
''/alice/path'' }, { name => ''bob'',
path => ''/bob/path'' } ]

(in template)
<% @users.each do |user| %>
    /bin/mount --bind <%= user[''path''] %> /home/<%=
user[''name''] %>
<% end %>

Re: [Puppet Users] Loop with two variables in puppet

Hi Jiří,

you could use a simple hash to get the result you want. Using
Hash.each_pair [1] you can iterate over the keys and values in your hash
representing the mount points.

Example:

your_manifest.pp:

$mountpoints = { ''user1'' =>
''/home/some/path'', ''user2'' =>
/home/another/path'' }


your_template.erb:

<% mountpoints.each do |user, path| -%>
/bin/mount --bind <%= path %> /home/<%= user %>/www
<% end -%>


[1]: http://www.ruby-doc.org/core-1.9.3/Hash.html#method-i-each_pair


Best regards,
Jochen

Re: [Puppet Users] Loop with two variables in puppet

Unless you want to establish a proper data structure (array of pairs), 
I''d suggest Array#zip:

   http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-zip
