Example Playbook

This example is taken from molecule/default/converge.yml and is tested on each push, pull request and release.

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

  roles:
    - role: robertdebock.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. In CI this is done using molecule/default/prepare.yml:

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

  roles:
    - role: robertdebock.bootstrap

Also see a full explanation and example on how to use these roles.
