Depends whether you want puppet to fail the rest of the dependency of this
service or simply not perform any changes to the service state but allow the
rest of the manifest to process without any issues.
In the first scenario, require an exec which checks for file absent. In the
second scenario, write a custom fact $maintenance (recommend prefixing your
site name to the fact) and simply apply the meta-parameter noop => true and
Puppet simply won't make any changes to the service state:
# maintenance.rb
Facter.add("maintenance") do
setcode do
File::exists?("/path/to/file")
end
end
# in Puppet Class
If ${maintenance} {
notice ("System in maintenance mode.")
Service {
noop => true,
}
}
Not sure if it's ideal, since both solutions will generate a fair amount of
logging.
Thanks,
