Example Playbook

Below is an example playbook taken from molecule/default/converge.yml. This playbook is tested with every update and release.

---
- name: Converge
  hosts: all
  become: true
  gather_facts: false

  roles:
    - role: buluma.ulimit
      ulimit_items:
        - limit_item: nofile
          domain: root
          limit_type: soft
          value: 1048576
        - limit_item: nproc
          domain: root
          limit_type: soft
          value: 1024
        - limit_item: nproc
          domain: root
          limit_type: hard
          value: 2048

The machine needs to be prepared first. In CI, this is done with molecule/default/prepare.yml:

---
- name: Prepare
  hosts: all
  become: true
  gather_facts: false

  roles:
    - role: buluma.bootstrap
