debian:stable-slim で作ったコンテナに MySQL を入れる

はじめに

どこかから、

RUN apt-get update && \
	apt-get install -y mysql-server python3 python3-pip && \
	pip3 install awscli && \
	apt-get autoremove -y && \
	apt-get remove -y python3-pip && \
	apt-get clean && \
	rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

というコードを拾ってきたので動かそうとしていた。

ただ最近の Docker イメージは slim というのを使えばいいと何かで見たので、FROM debian:stable-slim を指定して docker build してみたらどうもビルドに失敗する

 => CACHED [1/4] FROM docker.io/library/debian:stable-slim  0.0s
 => ERROR [2/4] RUN apt-get update &&  apt-get install -y   4.0s
