Changing the order of 'run_list'

Tiago_Cruz · June 5, 2015, 3:01pm

Ohai!

To add one recipe before other, I can use:

knife node run_list add lasvegas1 ‘role[base]’ --before ‘role[web]’

But I can’t do this using recipe:

if not node.run_list.roles.include?(‘base’)
ruby_block “Add base role before web” do
block { node.run_list.add(“role[base]”).before(“role[web]”) }
end
end

How can I do this?

Thanks!

The run list is just a ruby array, use ruby’s Array methods for this.

Hello Daniel, thanks for your time!

Could you please help with some example? I think that I don't get yet

Try 1:

node.run_list.add("role[base]", --before, "role[web]")

[2015-06-05T17:51:29+00:00] ERROR: ruby_block[Add base before web]
(test::web line 7) had an error: NoMethodError: undefined method `before'
for Chef::Resource::RubyBlock

Try 2:

node.run_list.add("role[base]", before, "role[web]")

Try 3:

node.run_list.add("role[base]", "before", "role[web]")

This is not something you should generally do as changing the run list from inside recipe code probably won't have the effect you expect. Notably it won't have any effect until the next run assuming the current one succeeds.

As to your specific question: node.run_list.run_list_items.insert(node.run_list.find('role[base']), 'role[web]'). You can find more information in the Ruby documentation for Array#insert and Enumerable#find.

Thanks Noah,

I was unable to config this as you said, but I'll post my ugly solution
here to help someone in the future:

add role 'base' before the main one after first run

ruby_block "Add base before web" do
block {
node.run_list.remove("role[web]")
node.run_list.add("role[base]")
node.run_list.add("role[web]")
}
not_if { node.run_list.roles.include?('base') }
end
