Python For DevOps: An Ultimate Guide

By Sakshi Pandey, Community Contributor -

DevOps consists of a collection of technologies, work procedures, and techniques intended to increase the effectiveness and efficiency of the software development lifecycle. One of the core principles of DevOps is continuous integration and delivery. 

The main contributor to success of CI/CD is the creation of a team of individuals who can develop, test, and maintain software themselves. This process was created to help businesses make themselves more competitive by producing software more quickly, without sacrificing quality. Not only does this greatly speed up software development and productivity, but it also ensures better maintenance of the application. Due to the foreknowledge the team has of all aspects of the software, new features/updates can be rolled out quickly.  

Python is a high level programming language prized for its extensive libraries, flexibility, and ease of use. All of these traits have made Python one of the most popular languages to use for DevOps.

How to use Python for DevOps Processes

Python is versatile and can be used in multiple stages of the DevOps lifecycle, from continuous monitoring to deployment. 

DevOps LifecycleSource

Following are some of the key uses of Python in the phases of the DevOps lifecycle:

  • Planning

Python has several libraries which make it particularly well suited to gather important statistics for the software during the planning and information gathering phase. Automation tools can be programmed to gather statistics, perform data cleaning, data manipulation, data analysis, and to create data visualizations. 

  • Development

Python can be used to write scripts which can configure tools, and automate tasks. In addition to this, Python has modules which make it easy for developers to interact with, and carry out tasks in databases such as SQLite, MySQL, MongoDB, and PostgreSQL. Python can also be used to interact with version control systems through the Gitapi module.  Lastly, the ability of Python to be used across various development environments, and the availability of modules such as OS and subprocess to interact with the underlying operating system and spawn child processes can be very useful to developers.

  • Build and Testing

Python can be used to write automated scripts to help with the build automation process. Testing frameworks like Selenium and libraries like pytest can be used to write complex and highly effective automation test scripts in Python. Additionally, if Django is used in the development phase then the built-in testing framework in Django can also be utilized.

  • Deployment

Python can also be used to script the deployment programs. Additionally, it can assist with the deployment, configuration, and management of the applications from the development phase to the testing and production environments. Purely written in Python, configuration management tools like Ansible can be made more productive by writing additional custom modules in Python.

Python’s well-known Cuisine and Fabric modules are very popularly  used in DevOps for the deployment phase.

  • Monitoring and Operations

With the aid of Python, scripts that can be used for automation of daily monitoring tasks can be written. These scripts can have the additional functionality of generating and sending out notifications to all relevant parties in case of any issue/error found.

Python also has cross-platform libraries for process and system monitoring, such as psutils which can be highly helpful to monitor and check for any inconsistencies or errors during the development, build, testing, and deployment phases. Python scripts can be written to routinely check drivers, network devices, and also to automate any sysadmin tasks.

Some of the popular Python Libraries and Tools that are used for DevOps Automation in Python are: 

  1. Pandas
  2. Selenium
  3. Pytest
  4. Beautiful Soup
  5. Jenkins
  6. SciPy
  7. Behave
  8. Ansible
  9. BrowserStack Automate
  10. TensorFlow

1. Pandas

PandasThe Pandas module is a highly useful module for data analysis and very popular among data analysts and data science engineers. The Pandas dataframe is capable of efficiently handling large amounts of data and also allows users to gain insights and extract useful information from the data.

2. Selenium

SeleniumSelenium is a very well-liked open-source Python library renowned  for aiding developers design automated test cases which can be executed across different browsers through drivers.Testing the functionality of a button, or carrying out tasks such as filling out a form, navigating a web application, these are all tasks which can be done using sub-modules and drivers with Selenium.

Selenium offers a vast collection of open source tools that are helpful for all types of automation problems. Automation testing frequently takes a long time, creating test cases, carrying them out, and verifying them can be difficult. However the benefits far outweigh the drawbacks. There are so many different browser versions, operating systems, and devices that tests need to be run on, and without automation testing it would be nearly impossible to test on all browser/OS/device combinations. 

However this testing is possible through platforms like BrowserStack. BrowserStack’s Cloud Selenium Grid, enables developers to execute automation test scripts on more than 3000 actual device/browser/OS combinations.
