Examples

# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

- name: Create job with two steps
  ovirt_job:
    description: job_name
    steps:
      - description: step_name_A
      - description: step_name_B

- name: Finish one step
  ovirt_job:
    description: job_name
    steps:
      - description: step_name_A
        state: finished

- name: When you fail one step whole job will stop
  ovirt_job:
    description: job_name
    steps:
      - description: step_name_B
        state: failed

- name: Finish all steps
  ovirt_job:
    description: job_name
    state: finished
