Molecule Scenarios

Molecule is being used to test the “tripleo_auditd” role. The following section highlights the drivers in service and provides an example playbook showing how the role is leveraged.

Scenario: custom_rules

Molecule Inventory
hosts:
  all:
    hosts:
      instance:
        ansible_host: localhost
Example custom_rules playbook
- name: Converge
  hosts: all
  vars:
    ordered_rules:
    - -a always,exit -F arch=b64 -S adjtimex -F key=audit_time_rules
    - -a always,exit -F arch=b64 -S settimeofday -F key=audit_time_rules
    - -a always,exit -F arch=b64 -S clock_settime -F key=audit_time_rules
  tasks:
  - name: Push some rules
    vars:
      tripleo_auditd_rules:
        Record attempts to alter time through settimeofday:
          content: -a always,exit -F arch=b64 -S settimeofday -k audit_time_rules
          order: 2
        Record attempts to alter time through adjtimex:
          content: -a always,exit -F arch=b64 -S adjtimex -k audit_time_rules

    command: /sbin/auditctl -l

  - name: Ensure rules are present in the correct order
    assert:
      that:
