I am trying to call the data_bag_item method within an erb template. My
sudo users may have multiple sudo cmds so i have embedded them directly into
the user’s databag like so
file: users/oper.json
{
“id”: “oper”,
“groups”: “oper”,
“uid”: 977,
“shell”: “/bin/bash”,
“password”: “$1$WV1cZLkt$FmFEuRFCGKWaabud6.Gld1”,
“sudo_cmds”: [ “ALL=(ALL) NOPASSWD:/sbin/reboot”,
“ALL=(ALL) NOPASSWD:/sbin/poweroff” ]
}
file: recipes/default.rb
sudoers = []
data_bag(‘users’).each do |user_name|
u = data_bag_item(‘users’, user_name)
if u['sudo_cmds']
sudoers << u['id']
end
end
template “/etc/sudoers” do
source "sudoers.erb"
mode 0440
owner "root"
group "root"
variables(
:sudoers => sudoers
)
end
file: sudoers.erb
User privilege specification
root ALL=(ALL) ALL
<% @sudoers.each do |user|
cmds = data_bag_item(‘users/#{user}’, ‘sudo_cmds’)
cmds.each do |cmd| -%>
<%= user %> <%= cmd %>
<% end
end -%>
Here is the error i get when I try to do this
