Template question


#1

I have a template

template “/etc/djo.dat” dosource "djo.dat.erb"mode 0644owner "root"group "root"variables({:domain => node[:domain],:pete => “jimmy”})end

I want pete = to different fixed values based on node[:domain]what is the best way to do this?


#2

Where is the pre-populated value mapping stored?

If it’s in a databag, you can/should be able to do something like this:

knife data bag edit who_is pete

{ “id”: “pete”,
“foo_node”: “jimmy”,
“bar_node”: “jammy”,
“baz_node”: “johnny”
}

and have the section of the template read like something along these lines:

variables ({
:domain => node[:domain],
:pete => data_bag_item(“who_is”, “pete”)[node[:domain]]
})

I tend to make the data_bag_item call before the template and
establish a variable then de-reference that because it’s easier to
print out/debug that, but it’s not always necessary.

#3

:pete => node[:domain] == “foo.com” > “bar” : “baz”

or

pete = case node[:domain]
when “foo.com
"foo"
when /bar.com$/
"bar_and_sub"
end

variables({…, :pete => pete})

Untested but approximately that. It helps if you realise that this is Just Ruby (helps me anyway. Also helps here if you know ruby, mind.)

This was meant to be

:pete => node[:domain] == “foo.com” ? “bar” : “baz”
