In which case the rescue block will be executed followed by the always block. Let’s have a look at that playbook once again.

In this sample playbook ansible-blocks-2.yml we have created two tasks inside the block wherein one task will pass while the other is expected to fail. Validate the nodejs installation is successful and print version using debug and assert. Install necessary commands and tools using apt module pretasks. In this playbook, we are going to perform the following tasks. The playbook author will write it that way.
#ANSIBLE TASKS HOW TO#
When you created your first playbook in a previous part of this guide, you defined a single task that outputs a message using debug. Let us see how to use ansible pretasks and posttasks in the ansible-playbook practically. In Ansible, it is typical to assume a tasks file exists within a given project. These are also often used to abstract commands across different operating systems. Modules offer shortcuts to execute operations that you would otherwise have to run as raw bash commands. Then, you’ll be able to determine which tasks you’ll need and which modules you can use to reach your goals in less steps. Before automating a procedure such as setting up a LEMP server, you’ll need to assess which manual steps are necessary and the order in which they must be completed to get everything done. Playbooks typically contain a series of tasks that serve a goal, such as to set up a web server, or to deploy an application to remote environments.Īnsible executes tasks in the same order they are defined inside a playbook. You can create the task from Task Template by clicking the button Run/Build/Deploy for the required template. A task is the smallest unit of action you can automate using an Ansible playbook. A task is an instance of launching an Ansible playbook.
