[chef] Re: How to execute a command block only if previous block succeed?

[Cassiano Leal < >]

You're asking two different questions here, and the solution will depend on which is actually the case.

If you really just need for one resource to be dependent on the other, use the action :nothing / notifies pattern:

execute "bye" do

  command "xxx"

  action :nothing

end

…

foo "bar" do

  action :helloworld

  notifies :run, "execute[bye]"

end

If you actually need to send the exit status from one resource to the other, then you'll probably need to hack something on your provider to populate a node attribute, I think… :)

I have written a custom provider, foo

And in my recipe, I have lines..

foo "bar" do

  action : helloworld

end

..

execute "bye" do

  command "xxx"

  action :run

end

How to make my last execute block run only if my custom provider "foo" is executed correctly?

i.e. How to make my helloworld action return success/error status and such that the later block can make use of this value?

Thanks.
