How to Print EC2 Tags in Ansible: A Step-by-Step Guide

When managing Amazon EC2 instances with Ansible, tagging your resources correctly is crucial for organization and management. However, one common issue that many users face is how to effectively view these tags after they've been applied. Specifically, if you're attempting to print the list of EC2 tags that you’ve registered, a few simple tips can help you resolve the problem.

The Challenge: Printing EC2 Tags in Ansible

You might find yourself in a situation like the following:

You've run a playbook to get your EC2 instance tags using the ec2_tag module.

You’ve registered the output in a variable, but when you try to print it using the debug module, you see no values returned.

For example, the following code segment will help you retrieve your EC2 tags:

However, simply trying to display my_ec2_tags might not yield results, leading to frustration.

The Solution: Tagging Your Debug Task

The key to solving this issue lies in ensuring that the task you are using to print the tags also has the same tag as the task that retrieves them. Here’s how you can effectively display the EC2 tags:

Step 1: Modify the Debug Task

To print the values stored in the my_ec2_tags variable, you need to be specific about what you want to see. Since the tags you are interested in are stored under my_ec2_tags.tags, you should modify your debug task as follows:

Step 2: Run Your Playbook

After making these changes, rerun your playbook. The inclusion of the same tag in your debug task as in your tagging task ensures that the debug task gets executed and prints the expected output.

Conclusion

By following these simple adjustments, you can effectively print your EC2 tags using Ansible, making it easier to manage and view the tags associated with your Amazon EC2 instances. Remember, aligning your task tags is essential for ensuring that all tasks are executed correctly.

Key Takeaways:

Use the ec2_tag module to retrieve tags from your instances.

Register the output in a variable.

Make sure your debug tasks have the same tags for visibility.

To access the tags, refer to my_ec2_tags.tags.

This guide will streamline your workflows and enhance your ability to manage EC2 instances effectively using Ansible.
