[chef] Re: Iterating through parameters when a resource is retried

[Brian Hatfield < >]

I wanted to bump this thread because I realized a more succinct way to ask my question:

Is there a way to cleanly handle the failure of a resource or a set of resources such that I can then perform some 'graceful degradation' action? (IE; 'begin...rescue' in regular ruby parlance, but that does not apply here)

Thank you!

Given a resource like the following:

apt_repository "global-generic" do

    uri "SOMEURI"

    distribution "SOMEDISTRO"

    keyserver key_server

    key apt_key

    retries 2

end

it will retry if for example the keyserver is not reachable. For whatever reason, we are finding that large number of keyservers are not long-term reliable, or we are getting blocked, or something, but our keyserver requests time out.

What I would like to do is make keyserver be a list, and if the first item on the list fails, iterate to the second and so-on.

However, when I try this (ie, key_servers.pop), in practice it pops one item off the list and retries that item over and over rather than 'pop'ing a new item on each retry. I get that this is because of the way that convergence and such occurs, but is there any way for me to retry with different values?

Thank you!
