[chef] Re: Notifications and data

[Matthew Moretti < >]

I think I might see the problem.  During the compile step, the "set_empty_password" script resource is, in fact, compiled once for each user. However, because it has the same name attribute each time, you end up over-writing the resource; hence the last user in the list wins.

You could fix this with something like

script "set_empty_password_for_#{u[:id]}" do
  ...
end

And putting

notifies :run, "script[set_empty_password_for_#{u[:id]}]"

in your user block.

My solution feels a little hackey, though, so perhaps there's a better way to achieve what you're looking for.  I'm pretty new to this whole thing,

Hi,

I have some trouble with "notifies".. hope it's easy to explain to a chef-starter :)

I've modified the "users" cookbook [1] to set an empty password and (usermod -p "") and forcing password change on next login (chage -d 0).

Therefore I've extended the cookbook inside the
> search(:users, 'groups:sysadmin') do |u|

loop with the following block:

>   script "set_empty_password" do
>     interpreter "bash"

To notify it upon user creation, I've added
> notifies :run, "script[set_empty_password]", :immediately

to the following block:

>   user u['id'] do
>     uid u['uid']
>     gid u['gid']

My problem, however, is that in the bash script, #{u[:id]} is always the user name of the user returned as *last* from search (so for every user it always modifies the same one). set_empty_password is executed, but with wrong data..

I've uploaded the complete file here:

Can you tell me the reason for this?

Thanks a lot for your help!
