I've open a bug ticket:
puppet --graph misses some dependencies
https://tickets.puppetlabs.com/browse/PUP-2075
d1 {'test': }
->
d2 {'test': }
define d1 {
exec { exec1: command => '/bin/echo exec1; exit 1' }
}
define d2 {
exec { exec2: command => '/bin/echo exec2; exit 1' }
}
---
$ puppet apply --graph test.pp
the graph does not show any dependency between exec1 and exec2.
However the dependency does exists, as puppet does nor execute exec2
because of "failed dependencies":
$ puppet apply --graph dd.pp
Notice: Compiled catalog for mac4c.local in environment production in 0.08
seconds
Notice: /Stage[main]//D1[test]/Exec[exec1]/returns: exec1
Error: /bin/echo exec1; exit 1 returned 1 instead of one of [0]
Error: /Stage[main]//D1[test]/Exec[exec1]/returns: change from notrun to 0
failed: /bin/echo exec1; exit 1 returned 1 instead of one of [0]
Notice: /Stage[main]//D2[test]/Exec[exec2]: Dependency Exec[exec1] has
failures: true
Warning: /Stage[main]//D2[test]/Exec[exec2]: Skipping because of failed
dependencies
Notice: Finished catalog run in 0.11 seconds
So, it seems that there is a bug in puppet --graph.
