Python for DevOps
Learn Fiercely Effective Automation
The world has changed a lot in the last decade: Python is one of the most popular languages in the world, the cloud is ubiquitous, and data is hot. Another big change is everyone needs some type of automation. This course covers fiercely effective ways to “get stuff done” in Python. This will be taught using Colab, an interactive Jupyter environment, with hands-on code examples throughout the course.
With software systems, for every failed perfect solution that never got implemented, there is a reasonable solution that could have improved things. Learn to embrace imperfect, but useful, automation and you will never look at a boring task the same way again.
What you'll learn-and how you can apply it
By the end of this live, hands-on, online course, you’ll understand:
- Continuous Delivery with Python
- Testing, linting and code quality with Python
- How to automate tasks with command-line tools in Python
And you’ll be able to:
- Build command-line tools with the Click Framework
- Use the subprocess module to run Unix shell commands
- Create a continuous delivery process using CircleCI from scratch
This training course is for you because...
- You are a DevOps engineer and want to automate tasks more effectively
- You perform IT and want to get into DevOps
- You are a developer who wants to become better at DevOps
- Beginning Python skills (or proficiency in a scripting language and a basic understanding of Python syntax)
- Basic understanding of cloud computing concepts
- Comfort working with Linux
- Download or clone the code repository for the course: https://github.com/paiml/python_devops_book
- Get a refresher on any unfamiliar Python concepts by watching Python for Data Science Complete (video course) or reviewing any relevant portions of Python for Data Science (website).
- A free Google account will be needed to access notebooks in Google Colab. While a Google account is not required, it is strongly recommended to get the benefit of full participation with the exercises. (If you are unable to use Google Colab, a downloadable notebook will be available via a Github repo.)
- Explore Essential Machine Learning and Pragmatic AI (learning path). Learn about cloud-native Machine Learning with a DevOps mindset with examples showing how to perform AI/ML tasks with Python.
- Explore AWS Certified Machine Learning-Specialty ML (learning path). Learn how to operationalize AWS Machine Learning models and apply cloud-native DevOps patterns with this video.
- Read Cloud Native DevOps with Kubernetes (book). In this friendly, pragmatic book, cloud experts John Arundel and Justin Domingus show you what Kubernetes can do—and what you can do with it. You’ll build, step by step, an example cloud-native application, and its supporting infrastructure, along with a development environment and continuous deployment pipeline that you can use for your own application.
- Read Python for DevOps (book). Continue on your DevOps journey and learn to automate tasks using Python, work with continuous integration systems, and mix shell and Python commands to solve problems.
