What Scripting Language Does Kubernetes Use?


Heather Bennett

In the world of container orchestration, Kubernetes has emerged as the de facto standard. It provides a robust platform for managing, scaling, and automating containerized applications.

But have you ever wondered what scripting language powers this powerful tool? Let’s dive in and explore the scripting language used by Kubernetes.

The Role of Scripting Languages in Kubernetes

Scripting languages play a crucial role in the operation and configuration of Kubernetes. They enable administrators and developers to define and automate tasks, manage resources, and customize the behavior of their Kubernetes clusters. These languages are used to write scripts that interact with the Kubernetes API server, allowing users to perform various operations such as deploying applications, scaling resources, and managing configurations.

Primarily Used Scripting Language: Bash

While there are several scripting languages that can be used with Kubernetes, one language stands out as the primary choice for scripting: Bash. Bash (short for “Bourne Again Shell”) is a widely-used Unix shell and command language that provides a powerful set of features for scripting purposes.

With Bash scripting, you can interact with Kubernetes clusters using commands like `kubectl`, which is the official command-line interface for interacting with Kubernetes. You can write scripts that leverage `kubectl` commands to automate various tasks such as deploying applications, creating pods or services, managing secrets, and more.

Beyond Bash: Other Scripting Languages

While Bash is the most commonly used scripting language in the context of Kubernetes operations and automation, it’s worth mentioning that other languages can also be utilized.


Python is another popular choice among developers who want to script their interactions with Kubernetes. Python’s simplicity, readability, and vast ecosystem make it an attractive option. Python offers several libraries and frameworks, such as kubernetes-client, that provide higher-level abstractions for working with the Kubernetes API.


As Kubernetes itself is written in Go, it’s only natural that Go can also be used for scripting tasks. Go provides a powerful standard library and excellent support for concurrency, making it suitable for building robust automation scripts.

JavaScript (Node.js)

With the rise of JavaScript as a versatile language, it has become increasingly popular in the context of Kubernetes scripting. Using libraries like kubernetes-client/node, developers can leverage JavaScript’s asynchronous nature and event-driven architecture to build scalable automation scripts.

Choosing the Right Scripting Language

The choice of scripting language depends on various factors such as familiarity, project requirements, performance needs, and existing codebase. Bash is often favored due to its simplicity and availability on most Unix-like systems. However, if you are already proficient in another language like Python or Go, leveraging that expertise might be a more suitable option.

  • Bash: Suitable for quick scripts or simple automation tasks.
  • Python: Ideal for complex automation workflows or when leveraging its extensive ecosystem is beneficial.
  • Go: Recommended if you prefer a statically-typed language with excellent performance characteristics.
  • JavaScript (Node.js): Great for building scalable automation scripts with event-driven architecture.

In Conclusion

Kubernetes offers flexibility when it comes to choosing a scripting language. While Bash remains the default choice due to its simplicity and wide adoption, other languages like Python, Go, and JavaScript (Node.js) can also be used to script interactions with Kubernetes.

The choice ultimately depends on your familiarity, project requirements, and the specific strengths of each language. So go ahead and leverage the power of scripting to automate and streamline your Kubernetes workflows!
