Foreword

DevOps work can seem mysterious to many people, who may not even know where to begin. However, a good starting point is to learn the basics of working in a terminal, which is a command-line interface for interacting with a computer's operating system. It's important to keep in mind that DevOps can be a challenging field with a steep learning curve, and the complexity of tasks can vary depending on the specific project or task at hand.

Core Technologies

Linux

DevOps work often involves working with Linux servers, so it's essential to have a basic understanding of Linux commands, file system structure, and permissions. There are many online resources and tutorials available to learn Linux basics.

Git

Git is the most widely used version control system, and it's essential to understand how it works as it's used to manage code repositories and collaborate with others. There are many online tutorials available to learn Git.

Scripting

Scripting languages like Bash, Python, and Ruby are essential in DevOps work as they're used to automate tasks and write scripts that interact with servers and applications.

Containerization

Containers are an important part of modern DevOps practices as they allow for easier deployment and management of applications. Docker is the most popular containerization technology, and there are many online resources available to learn Docker basics.

Tools

There are many DevOps tools available, such as Ansible, Terraform, and Jenkins. It's a good idea to pick one or two and start practicing with them to get a better understanding of how they work.

Conclusion

DevOps work can be daunting for beginners, but learning the basics of working in a terminal is a good starting point. A fundamental understanding of Linux, Git, scripting languages like Bash, Python, and Ruby, and containerization technologies such as Docker is essential for DevOps work. Moreover, learning how to use DevOps tools such as Ansible, Terraform, and Jenkins is also important. While DevOps has a steep learning curve, with dedication and practice, anyone can become proficient in this field.
