How to Install libvips on a Golang Docker Container

If you're working with images in a Golang application, you might encounter the need for a powerful library like libvips. This library is efficient for image processing tasks and can greatly enhance your application's performance. However, installing libvips within a Docker container, especially one that's set up to run Golang applications, can be tricky. In this post, I will walk you through the process of installing libvips in your Golang Docker container step-by-step.

Understanding the Problem

Docker containers are lightweight and standardized environments that simplify the deployment of applications. However, setting up the necessary libraries and dependencies for specific functionalities can often feel daunting. The key is to understand how Docker manages installations and packages in its environment.
