Ok, here’s an actual trace. In this case, I have a recipe that installs Cassandra.
Service_name=”flexnet-cassandra”
rpm_package “Install Cassandra” do
action :install

end

Subject: [chef] Re: Re: Puzzled about convergence, please advise?
The template resource does most of that work inside the provider at compile-time. The resource is used to validate that your arguments to the resource are valid, its not until you get into define_resource_requirements inside of the provider that you would
throw the EnclosingDirectoryDoesNotExist exception.
As far as I can tell the example Chris gives should work, so we probably need the real code and the real output showing the actual exception, plus the backtrace. Offhand I'd suspect something more like a simple "/opt/some_path/conf" vs. "/opt/some-path/conf"
typo but there's not enough information to say. However, I would have expected either an EnclosingDirectoryDoesNotExist or the error message about the source of the template not being found for the simple "file not found" cases that I can think of. If chef
is spitting back a stock "No such file or directory" then I'm not sure what code path is getting hit without the text of the exception and ideally the backtrace.

resources are executed at converge time, but they are built (resource collection) during compilation time. to build the template resource u need to read the template file, inject variables and finally in converge tim check if that differs
from the existing one and replace it. so the resource building part itself requires the file to be present.
you dont need template here, you want remote file with
file:/// as source, can you try that?

I thought I understood this, so I’m puzzled that it’s not working the way I think it should work. I have the following simple recipe.
rpm_package “Installing RPM” do
action :install
package_name myRPM.rpm
end
template “/opt/some_path/conf/myRPMconfig.xml” do
source “myRPMconfig.xml.erb”
end
I expect both resources to be executed during convergence (run time), correct?
If so, the rpm_package should install myRPM.rpm, which creates the /opt/some_path/conf directory, so when the template resource runs, the directory is already there. However, when
I run chef-client, I get an error saying “No such file or directory - /opt/some_path/conf”
I know that myRPM.rpm creates the directory because if I install it manually, it does create it.
Any advise?
