Single node example config fails to bootstrap if no UF in the splunk_config.yml

[guilhemmarchand]

Describe the bug The sample standalone config in:

example/single_node.yml

Fails to proceed unless at least one uf is part of the configuration.

To Reproduce

cp examples/single_node.yml config/
cd config
vagrant up; ansible-playbook ansible/deploy-site.yml

Screenshots

Ansible fails at:

TASK [common : Check SELinux state] **************************************************************************************************************************************************************************************************************************
fatal: [shidx]: FAILED! => {"msg": "The conditional check 'inventory_hostname not in groups.role_universal_forwarder' failed. The error was: error while evaluating conditional (inventory_hostname not in groups.role_universal_forwarder): 'dict object' has no attribute 'role_universal_forwarder'\n\nThe error appears to be in '/Users/guilhem/Vagrant/Splunkenizer-preprod/ansible/roles/common/tasks/disable_selinux.yml': line 4, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Check SELinux state\n  ^ here\n"}

If a UF is enabled, in splunk_config.yml:

---
# splunk_config.yml

# General settings
general:
  start_ip: 172.16.2.100

os:
  time_zone: "Europe/London"

virtualbox:
#  box: "centos/7" # Default
#  box: "ubuntu/xenial64"

# Splunk default settings
splunk_defaults:
  splunk_env_name: geodis
#  splunk_version: '6.5.7'
#  splunk_admin_password: 'splunklab'
  splunk_license_file: Splunk_Enterprise.lic
#  splunk_indexes:
#    - test1
#    - test2

# Splunk hosts with its settings
splunk_hosts:
  # Indexer and Search Head on single node
  - name: shidx
    roles:
      - indexer
      - search_head

   # Universal Forwarder
  - name: ufpre
    roles:
      - universal_forwarder

The deployment proceeds successfully as expected, otherwise fails with just the single node.

Desktop (please complete the following information):

• OS: OSX
