Alpine Docker

Alpine Docker#


Use like you would any other base image:

FROM alpine:3.7
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:18.04
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.
