Overriding chef built-in providers

Chef Infra (archive)
1

Hi! I would like to override the mount provider so that it does try to
mount in my dev environment . . I was hoping to add a mount cookbook with
a provider that would simply check the chef environment and make super
calls if the environment is not dev.

Is this stupid? Anyone have a better way? If this doesn’t sound terrible,
then can someone say if what I want to do is possible? I couldn’t find
anything on the nets about overriding providers . .

Thanks a lot,
Guy

Why not enclosing the mounts with a

if node.chef_environment != 'dev' do

[... mounts calls and so ont ... ]

end

or a

do

[...]

end unless node.chef_environment == 'dev'

For what it worth, I wrote that without control, so I may have typos and
other cross language errors, but the idea is there :slight_smile:

Thanks, but I'd rather do it in one place, and be able to change it there
rather than have to change it throughout my code if my requirements change

I just today learned how to override one of chef's providers with a
heavyweight provider, code snippet here:

You could set an attribute foo.nomount = true on the environments. When you call a mount resource include a not_if { node.foo.nomount } in then resource block.

Advantages: You don’t block the mount resource on certain environments. You use the attribute as a toggle able feature flag. Its not a method like chef.environment so an attribute may be easier to change across systems.
