During the initial deploy, running tripleo::profile::base::keystone
fails with:
"Error: Could not set 'present' on ensure: undefined method `new'
for nil:NilClass at
/etc/puppet/modules/tripleo/manifests/profile/base/keystone.pp:274",
It's likely erroring in the keystone_domain provider.
https://github.com/openstack/puppet-keystone/blob/master/lib/puppet/provider/keystone_domain/openstack.rb#L115-L122
or
https://github.com/openstack/puppet-keystone/blob/master/lib/puppet/provider/keystone_domain/openstack.rb#L155-L161
Providers are notoriously bad at their error messaging. Usually this
error happens when we get a null back from the underlying command and
we're still trying to do something. This could point to a
misconfiguration of keystone if it's not getting anything back.
Per Alex comment, the keystone_domain class is definitely involved.
The provider fails: "Could not set 'present' on ensure"
And the propagated error seems to be because the provider could not be
set up for some dependent reason and came back empty.
$ irb
irb(main):001:0> nil.new
NoMethodError: undefined method `new' for nil:NilClass
The second pass worked because the missing "dependent" bit was set up
(in the meantime) and the provider creation was satisfied.
To investigate dependent cause within the provider, you could use
'notice("Value: ${variable}")'
The line in question is:
70: if $step == 3 and $manage_domain {
71: if hiera('heat_engine_enabled', false) {
72: # create these seperate and don't use ::heat::keystone::domain since
73: # that class writes out the configs
74: keystone_domain { $heat_admin_domain:
ensure => 'present',
enabled => true
}
The thing is, despite the error...it creates the keystone domain
*anyway*, and a subsequent run of the module will complete without any
errors.
I'm not entirely sure that the error is telling me, since *none* of
the puppet types or providers have a "new" method as far as I can see.
Any pointers you can offer would be appreciated.
Thanks!

I don't. I have a local environment where I'm doing my testing.

Hey Lars,
Do you have a full job that's running which shows those issues?
Thanks,
Mohammed

[openstack-dev] Puppet debugging help?
Hey folks,
I'm trying to patch puppet-keystone to support multi-valued
configuration options (like trusted_dashboard). I have a patch that
works, mostly, but I've run into a frustrating problem (frustrating
because it would seem to be orthogonal to my patches, which affect the
keystone_config provider and type).
During the initial deploy, running tripleo::profile::base::keystone
fails with:
"Error: Could not set 'present' on ensure: undefined method `new'
for nil:NilClass at
/etc/puppet/modules/tripleo/manifests/profile/base/keystone.pp:274",
The line in question is:
70: if $step == 3 and $manage_domain {
71: if hiera('heat_engine_enabled', false) {
72: # create these seperate and don't use ::heat::keystone::domain since
73: # that class writes out the configs
74: keystone_domain { $heat_admin_domain:
ensure => 'present',
enabled => true
}
The thing is, despite the error...it creates the keystone domain
*anyway*, and a subsequent run of the module will complete without any
errors.
I'm not entirely sure that the error is telling me, since *none* of
the puppet types or providers have a "new" method as far as I can see.
Any pointers you can offer would be appreciated.
Thanks!
