We recently released a new online test in Ansible 2.4!

The test contains the following Ansible topics: 

  • Installation
  • Playbooks
  • Inventory
  • Module Index
  • Network Modules
  • Ansible-Container

 

An example question:

Considering the below playbook, which tasks will be executed first?

—
– hosts: webservers
  remote_user: root

tasks:
– name: ensure apache is at the latest version
  yum: name=httpd state=latest
– name: write the apache config file
  template: src=/srv/httpd.j2 dest=/etc/httpd.conf

– hosts: databases
  remote_user: root

tasks:
– name: ensure postgresql is at the latest version
  yum: name=postgresql state=latest
– name: ensure that postgresql is started
  service: name=postgresql state=started

 

Answers:

  1. apache first and then postgresql
  2. postgresql first and then apache
  3. They will both run in parallel
  4. The order of tasks is not guaranteed
