Top DevOps Voice – Docker Alpine vs Ubuntu

Part 1 | Why Alpine or Ubuntu?

Choosing between Alpine and Ubuntu as a Docker base image depends on specific project needs. Alpine is for its small size, security, and efficiency, making it ideal for simple applications where resources are limited, and is designed to run from RAM as often used for applications that require minimal overhead. Ubuntu is a more full-featured Linux distribution with a larger footprint; offering a broader range of pre-installed packages and is generally considered easier to use, especially if dealing with complex dependencies or need a system that’s closer to a traditional Linux environment. Alpine applies musl libc and busybox, whereas Ubuntu goes GNU libc. There are trade-offs but I go for either depending on needs. Both good for me.
