The Importance of Using Updated Python Versions in Ansible Remote Nodes

In the realm of automation and configuration management, Ansible plays a pivotal role. A common question among Ansible users is the significance of having a newer Python version on their remote nodes. Specifically, how does using Python 2.7 compare to newer versions, such as Python 3.6? Many might wonder if the version really affects the execution speed of playbooks or if it impacts compatibility with various modules. This guide aims to clarify these concerns and highlight the relevance of Python versions in your Ansible setup.

Why Python Version Matters

End-of-Life and Support Considerations

Both Python versions 2.7 and 3.6 have reached their end-of-life status. This means that:

Support is Variable: As these versions are no longer actively maintained, the availability of bug fixes and updates may be limited.

Module Compatibility: Many third-party libraries and tools drop support for outdated Python versions soon after they reach their end-of-life. Therefore, relying on older versions can lead to challenges with compatibility.

Security Implications

Although security updates are no longer provided for both versions, this might not seem critical in trusted environments. However, it’s essential to recognize that:

Other Systems: If your infrastructure is built on older software that has also reached its end-of-life, security vulnerabilities may arise.

Broader Impact: Operating systems and libraries that rely on outdated Python versions could have potential security risks, making it crucial to stay updated.

Performance: Execution Speed and Delays

One might expect that newer Python versions lead to faster execution of Ansible playbooks. However, the reality is a bit different. Here’s what you need to know:

Negligible Execution Speed Differences: For the most part, the performance enhancement between running Python 2.7 and Python 3.6 is unlikely to be significant.

Network Delays: The primary factors in playbook execution delays are often network round-trips rather than the Python version itself. Therefore, other optimization avenues may be more impactful for improving overall speed.

Conclusion: Updating Python Versions in Ansible

While it might seem that the differences in Python versions would have a substantial impact on Ansible's execution speed, the real focus should be on compatibility, security, and future-proofing your applications. Using updated Python versions not only ensures support for the latest features and modules but also helps mitigate any potential security risks associated with outdated software.

In conclusion, while you might not notice a drastic change in playbook execution speed, the long-term benefits of maintaining updated Python on your Ansible remote nodes are clear. Embrace the changes, and keep your systems robust and secure.
