In Ansible 2.0 blocks have been made available. Blocks allow you to group tasks in a logical way and they can also help for a better error handling. The majority of properties you can add to a standard task, you can also add it to the blocks. You may need to perform a yum task to install NTPd and enable of the service only if the machine is CentOS. To do so, the following code can be used:
tasks: - block: - name: Ensure NTPd is present yum: name: ntpd state: present - name: Ensure NTPd is running service: name: ntpd state: started enabled: True when: ansible_distribution == 'CentOS'
As you can notice, the when clause has been applied to the block so all tasks within the block will be performed only if the when clause will be true.
