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

[howard chen < >]

Unfortunately, there are more steps in between the two blocks (foo LWRP and execute) , so I can't notify immediately, e.g.

foo "bar" do

  action : helloworld

end

..

..(these steps need to be run first)

..

execute "bye" do

  command "xxx"

  action :run

end

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

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.
