Did you try using an update resource, and a build resource, where the
second depends on the first?
i.e. something like
exec { 'repository_update':
command => 'git pull',
}
exec { 'build':
command => 'make',
require => Exec['repository_update']
}
or, if you prefer:
exec { 'repository_update':
command => 'git pull',
}
exec { 'build':
command => 'make',
}
Exec['build'] -> Exec['repository_update']

Hello,
I've been trying to implement a puppet definition that uses vcsrepo and
notifies the caller through an update_notify parameter when the
repository contents change on disk. I have however found this very hard
to accomplish.
Basically I am trying to pull down a git repo and when the head of the
repo changes on the disk of the agent, run a build command (such as
make) into a release directory. So the system automatically tracks a
branch or responds to changes in tags and the system automatically
builds off of that information. In order to allow for multiple types of
build processes I am trying to notify other resources through the exec
notify property.
My problem is this:
The only way to trigger the notification in a conditional manner that I
have found is to use the onlyif or unless properties on the exec
resource. Notifications still happen on the exec command even if the
command fails so I can not use an inline command to notify or not (that
I know of). But the onlyif property which I have been trying seems to
execute before any of the actual commands so it always runs before the
vcsrepo update, which voids the intended purpose. I can not use
functions with a conditional because they are only run on puppet master
and also suffer from the same issue where they run before any commands,
and I can not use a fact because I need a directory parameter and it is
also runs before any of the commands.
So I need a way to conditionally trigger a notify during the course of a
execution run right after the vcsrepo gets done pulling down any
updates. Does anyone know how I might accomplish this task through
puppet? So far nothing I have tried works. I would think that this
goal would not be that isolated (building a repository after and only
after repository updates). In my case I normally build into release
directories so absolutely can not afford to rebuild on every puppet
execution which runs every 5 minutes.
Thanks for any help you can provide!
Adrian
