Essential Skills and Knowledge for Learning DevOps: Do You Need Coding Knowledge?

DevOps is a methodology that combines software development (Dev) and IT operations (Ops) to shorten the System Development Life Cycle (SDLC) and improve the quality and reliability of software delivery. If you're considering entering the field of DevOps, you might wonder about the basics required, particularly whether coding knowledge is necessary.

What Are Some Basics Needed to Learn DevOps?

Learning DevOps isn't just about acquiring a list of tools; it's about understanding both technical and procedural concepts. Here's an overview of the foundational knowledge and tools you'll need:

DevOps Tools and Technologies

While specific toolsets can vary depending on the organization you work for, a common set of tools in the DevOps toolkit includes:

Linux: Knowledge of Linux is crucial for most DevOps roles. Linux is widely used in server environments and for many of the DevOps tools. Familiarity with commands, file systems, and package management systems like APT and YUM is essential. AWS: Amazon Web Services (AWS) is one of the most popular cloud platforms in the DevOps space. Understanding cloud concepts, infrastructure as code (IAC), and services like EC2, S3, and RDS is critical. Jenkins: Jenkins is an open-source automation server that can be used to automate the various stages of the SDLC. Familiarity with its dashboard, pipelines, and plugins will help you manage and automate builds, tests, and deployments. Ansible: Ansible is a configuration management and application deployment tool. It is known for its agentless architecture and is used for managing configurations across multiple servers. Azure: Azure is another major cloud platform. While AWS is more commonly used, Azure has its own set of DevOps tools and services, including Azure DevOps. Maven: Maven is a build automation tool used primarily for Java projects. It helps in managing project dependencies and building processes. Git: Version control is a core aspect of DevOps. Knowledge of Git is essential for collaborating on code and managing different versions of software.

Basic Shell Scripting or Python

While coding is not the sole focus of DevOps, having a basic understanding of scripting languages is highly beneficial. Knowledge of either shell scripting (bash, zsh, etc.) or Python can significantly help in automating tasks and managing infrastructure.

Shell scripting is particularly useful for automating everyday tasks, such as running periodic checks on servers, managing backups, and updating configurations. Python, on the other hand, is a more versatile language that can be used for more complex automation tasks, data analysis, and even web development.

A Comprehensive Guide to Starting Your DevOps Journey

Here’s a step-by-step guide to getting started in DevOps:

Understand the Basics: Familiarize yourself with essential DevOps concepts like CI/CD (Continuous Integration/Continuous Delivery), infrastructure as code, and DevOps culture. Learn the Technical Stack: Dive deep into the tools you need to work with, including the ones mentioned above. Start from the bottom and build up your knowledge. Practice with a Project: Apply your knowledge to real projects. Use virtual machines or cloud environments like AWS or Azure to practice setting up and managing infrastructure and automation. Join Communities and Forums: Engage with the DevOps community through platforms like Stack Overflow, GitHub, and DevOps days. This will help you stay updated and get valuable tips and insights. Continuous Learning: DevOps is a continuously evolving field. Keep learning and adapting to new tools and best practices.

Conclusion

In summary, while coding knowledge is not always a strict requirement to start a DevOps career, it can certainly be an asset. Mastering the basics and staying updated with the latest tools and trends will help you excel in the DevOps field. Whether you choose to start with shell scripting or Python, the most important thing is to build a strong foundation and continuously learn and grow.
