GitHub Copilot Tutorial | How useful is it for Cloud and DevOps?

Introduction

In this article, we will delve into GitHub Copilot, an AI-powered code assistant, and evaluate its effectiveness for software engineers, especially those in cloud and DevOps roles. We will explore its features, benefits, and limitations through a detailed analysis and demo.

What is GitHub Copilot?

GitHub Copilot is an AI assistant designed to aid coding within IDEs like Visual Studio Code, IntelliJ, etc. It integrates directly into the code editor, offering real-time code suggestions based on the context of the code you're working on. This makes it distinct from other AI models like ChatGPT, where the AI operates through a web browser.

How GitHub Copilot Works

  1. Context-Aware: GitHub Copilot considers the files you are working on currently and their contents to make relevant suggestions.
  2. Auto-Completion: It predicts and completes code as you type, offering comments and code suggestions even if you don’t explicitly ask.
  3. Backed by OpenAI: It leverages a large language model trained on billions of lines of code and text.
  4. Limitations: GitHub Copilot's training data is from September 2021, making it potentially outdated for certain scenarios, especially in rapidly evolving fields like cloud and DevOps.

Setup and Integration

  1. Prerequisites: Ensure you have a GitHub account and access to AWS, Pulumi, Python, and Visual Studio Code.
  2. Installation: Set up GitHub Copilot within Visual Studio Code by installing the GitHub Copilot extension and signing in through GitHub.
  3. Configuration: Adjust setup settings to control data sharing and how closely suggestions should match public repository code.

Demonstration

Using GitHub Copilot for Code

  1. Generating Code: GitHub Copilot can generate code snippets based on comments or direct typing prompts. For instance, typing create 10 S3 buckets with unique names will generate a loop in Python creating those S3 buckets.
  2. Interop with Pulumi: For infrastructure as code (IaC) projects using Pulumi, Copilot can assist in both Python and Terraform.

Limitations for Infrastructure as Code

  1. Outdated Knowledge: Copilot relies on data from 2021. For example, it may use outdated AMIs or Kubernetes versions.
  2. Need for Verification: When working on IaC, engineers need to double-check the auto-generated code against up-to-date official documentation.

Comparison with Other Tools

While Copilot proves useful in many coding contexts, it is less reliable for current best practices in rapidly changing environments like cloud infrastructure. For Pulumi-specific tasks, Pulumi AI offers more recent data and configurations.

Practical Tips

  1. Code Translation: GitHub Copilot can translate Terraform code into Pulumi code.
  2. Voice Assistance: Although GitHub discontinued its voice extension, Visual Studio Code Speech can be used for dictating commands to Copilot.
  3. Error Handling: Copilot can help debug and explain errors in terminal outputs, aiding quicker fixes.

Conclusion

GitHub Copilot can significantly enhance productivity by speeding up the code-writing process, yet its practicality varies greatly depending on the task. Its outdated data can be a significant drawback for cloud and DevOps engineers, requiring them to manually verify and update suggestions. Despite this, Copilot's utility in explaining and generating code cannot be understated.
