公式 crenv rubyのスクリプトで処理が遅いと思うところでcrystalを取り入れてみようかな、程度のモチベーションで使ってみる。 crystalのDockerfileを示す。 yumで必須はgcc,git FROM centos:centos7.4.1708 MAINTAINER TestUser ENV container docker ##### crystal environment var ENV crystal_ver=0.20.0 #最新は投稿時点で0.24.1 ENV CRENV_ROOT=/usr/local/crenv ##### yum setting & install RUN yum update -y && yum clean all RUN yum swap -y fakesystemd systemd && yum clean all #RUN yum
