how to run multiple ansible plays in parallel?

Question

I have a playbook with multiple plays:

---
- hosts: druid-realtime-1
  sudo: true
  roles:
  - { role: druid-realtime, du_rt_id: 1 }

- hosts: druid-realtime-2
  sudo: true
  roles:
  - { role: druid-realtime, du_rt_id: 2 }

How do I tell ansible to run both plays in parallel instead of one after another?

Answer 1

You could do it this way

In your Ansible inventory, group your servers and assign a host variable:

[druid-realtime]
druid-realtime-1 id=1
druid-realtime-2 id=2

Then reference the variable in the playbook:

- hosts: druid-realtime
  sudo: true
  roles: 
    - { role: druid-realtime, du_rt_id: {{ id }} }
