Why is Alpine used as a base image?

Alpine is used as a base image in Docker due to its minimalism and lightweight nature. It is based on musl libc and busybox, making it very compact (usually around 5 MB), which significantly reduces the size of the final container. This is important for quick deployment, saving disk space, and enhancing security, as fewer components mean fewer potential vulnerabilities. In the context of Golang, where binaries are usually statically compiled, Alpine allows creating very lightweight and fast images without unnecessary dependencies.
