⁠What is Alpine Linux?

Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications. Read more about Alpine Linux here and you can see how their mantra fits in right at home with Docker images.

⁠How to use this image

Usage Use like you would any other base image:

FROM alpine:3.14 RUN apk add --no-cache mysql-client ENTRYPOINT ["mysql"] This example has a virtual image size of only 36.8MB. Compare that to our good friend Ubuntu:

FROM ubuntu:20.04 RUN apt-get update
&& apt-get install -y --no-install-recommends mysql-client
&& rm -rf /var/lib/apt/lists/* ENTRYPOINT ["mysql"] This yields us a virtual image size of about 145MB image.
