Ansible Tower Workflow: A Complete Guide for Efficient IT Orchestration

Ansible Tower provides a robust framework for automating IT tasks and managing workflows. Whether you’re using it for system configurations, deployments, or orchestration, understanding how to optimize your Ansible Tower workflow is crucial. In this guide, we’ll walk through the essential steps to set up and manage your workflows effectively.

What Is Ansible Tower Workflow?

Ansible Tower workflow involves combining various resources into a sequence of tasks with conditional job results. This ensures that your IT operations are automated, repeatable, and efficient. When integrated with services like DevOps, DevSecOps, or Cloud management, Ansible Tower can streamline your infrastructure and security needs.

Navigating the Ansible Tower Dashboard

When you log in to the Ansible Tower (AWX) dashboard, you’ll find a user-friendly interface designed to manage your IT orchestration tasks. The dashboard is divided into two primary sections:

• Top-left: This area allows administrators to access Projects, Inventories, Job Templates, and Jobs.
• Top-right: Here, you can configure Organizations, Users, Groups, and Permissions.

The main dashboard also provides a summary of your Hosts, Inventories, and Projects. You can view charts and graphs detailing Job Status and Host Status. Additionally, summaries of Recent Used Job Templates and Recent Run Jobs are available for quick reference.

Step 1: Creating a New Inventory

An inventory in Ansible Tower is a collection of hosts, which are grouped based on your project needs. To create a new inventory:

1. Navigate to the Inventories section and click the plus button to add a new inventory.
2. Enter a Name and Description, and leave the Organization field set to default for now.
3. Click Save to complete the inventory setup.

You can now add hosts to this inventory, either directly under the root or within specific groups. For instance, under the “test” inventory, click the plus button above Hosts to add a new host. Enter the host’s DNS resolvable name or IP address and click Save.

Step 2: Adding Credentials for Authentication

Credentials are vital for authenticating your Tower user to run Ansible playbooks against the inventory hosts. You can use passwords or SSH keys for this purpose.

To add a credential:

1. Go to Credentials in the setup section and click the plus button to create a new credential.
2. Choose Machine as the credential type, then enter the relevant details for authentication (password or SSH key).
3. Click Save to finalize the credentials.

Once added, you can use these credentials to run Ansible playbooks securely.

Step 3: Running Commands on Hosts

To ensure that your node is connected to Ansible Tower, you can use the ping module. Here’s how:

1. Go to Inventories, select the test inventory, and choose the host you created earlier.
2. Click on Run Command and select ping as the module.
3. Choose the node1 credential you created and click Launch.

Tower will direct you to the Jobs section, where you can track the Command Execution Status in real-time.

Step 4: Creating a Project

In Ansible Tower, a Project is essentially a collection of playbooks that you want to run. To create a project:

1. Click on the Projects link at the top of the dashboard and click the plus button.
2. Enter a Name and Description for your project.
3. Set the SCM Type to Git, and provide the GitHub URL for the playbook.

Step 5: Accessing and Managing Playbooks

To access your playbook, create a subdirectory for your project on the Tower server. For example, use the following command to create a directory for the tomcatcentos playbook:

mkdir /var/lib/awx/projects/ansible-tomcat

Then, use your preferred editor to create the playbook. After saving it, you can use the Tower interface to run it against the inventory host.

Step 6: Creating a New Job Template

A Job Template combines an Ansible playbook with the necessary settings to execute it. Here’s how to create a job template:

1. Go to the Job Templates section and click the plus button.
2. Enter a Name and Description for the template.
3. Select the Inventory, Project, and Credential from earlier.
4. Choose the playbook from the dropdown menu (e.g., tomcatcentos.yml).

You can customize other settings like Forks, Limit, and Job Tags. Once done, click Save to create the template.

Step 7: Launching a Job Template

To launch the job, navigate to the Job Templates section and click the Launch button next to the desired template. This action will redirect you to the Jobs section, where you can monitor the job’s progress. The page will refresh automatically using Tower’s live event feature.

Once the job completes, you can click stdout to view the standard output for the executed playbook.
