Hi All,
So here's my use case:
I've got an application with multiple environments, say live, qa and dev,
and each environment has multiple servers. The actual application requires
an NFS mount mounted on each of these servers. Each environment has it's
own NFS drive.
I also have a management server which needs to mount all these NFS drives
of every environment.
I use a mount resource included on each environment server to mount each
NFS drive, with the help of an $environment variable, which points it to
the right share on the NFS server, which is all working fine.
Now I want to puppetize the mounts of all NFS shares on the management
server as well, so I thought of using something like this in the actual
environment server manifest:
@@mount { mgmtnfs-$environment:
name => "/$path-$environment"
fstype => "nfs"
}
and I wanted to collect that in the management server manifest with
Mount <<||>>
Problem is that each exported resource must be globally unique across every
single *node*, not for every *environment*. That means that if two servers
export this resource to the same nfs mount I'll get an error. I don't want
an individual nfs mount on the mgmt server per node, but per environment.
So I can't use $host instead of $environment
If I would use local resources in the mgmt server manifest I would have to
set up 10 mount resources individually, since that's how many environments
I have. Actually 30, since every environment has not 1 but 3 separate NFS
mounts. Since that would be a manual step for every new environment, and
duplication of code, I consider it bad practice.
In my head the most elegant solution to this would be to have a resource
which is both virtual and exported, so that it can be requested to be
"realized" by every environment server, but is collected only once. I don't
think that is currently possible (or is it?). My questions are: Would it be
worth a feature request? And are there other ways to get this done in a
tidy manner?
Thanks
Stephan
