Description of problem: The check-network-gateway, ctlplane-iprange and dhcp-provisioning validations fail when the undercloud.conf file does not exist. This can happen when the deployer installs the undercloud with default values. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Install undercloud without having an undercloud.conf file 2. Run the check-network-gateway, ctlplane-iprange or dhcp-provisioning validation Actual results: The validation will fail saying that undercloud.conf could not be found. Expected results: The validation will run falling back to the default values. Additional info:
The ctlplane-ip-range and dhcp-provisioning validations no longer error as described in this bug, however there appears to be a syntactic issue with the check-network-gateway validation (undercloud) [stack@undercloud ~]$ openstack workflow execution create tripleo.validations.v1.run_validation '{"validation_name": "check-network-gateway"}' +-------------------+---------------------------------------+ | Field | Value | +-------------------+---------------------------------------+ | ID | 7ce1b86a-193f-4301-b3fd-866d08b390a6 | | Workflow ID | 2ad089d6-6622-4333-98d9-c0a90bde4fc6 | | Workflow name | tripleo.validations.v1.run_validation | | Description | | | Task Execution ID | <none> | | State | RUNNING | | State info | None | | Created at | 2017-11-02 18:06:44 | | Updated at | 2017-11-02 18:06:44 | +-------------------+---------------------------------------+ (undercloud) [stack@undercloud ~]$ mistral execution-get-output 7ce1b86a-193f-4301-b3fd-866d08b390a6 | jq .stdout -r Task 'Test network_gateway if different from local_ip' failed: Host: localhost Message: The task includes an option with an undefined variable.

(In reply to Florian Fuchs from comment #5) > Added a patch to fix the network gateway validation: > > https://review.openstack.org/#/c/518619/ This will need a backport once it's merged.
What does this validator check if there is no undercloud.conf? Does it ping 0.0.0.0 ?
Clarification: I was referring to check-network-gateway as an example of one of the validators. The logic in the other validators also needs some explanations, thanks.

The other validations mentioned above use the following default values: dhcp-provisioning: eth1 ctlplane-iprange: start: 192.0.2.5, end: 192.0.2.24
