Loop with two variables in puppet

[Jiří Červenka]

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.

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

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 -%>

Best regards,
Jochen
