centos 7 用Alpine跑了JDK8的镜像结果发现,JDK还是无法执行.后来翻阅文档才发现 Java是基于GUN Standard C library(glibc) Alpine是基于MUSL libc(mini libc) 安装参考: ~~~ https://github.com/sgerrand/alpine-pkg-glibc ~~~ Dockerfile ``` FROM alpine:latest ADD jdk-8u211-linux-x64.tar.gz /usr/local/ RUN echo http://mirrors.ustc.edu.cn/alpine/v3.9/main > /etc/apk/repositories && \ echo http://mirrors.ustc.edu.cn/alpine/v3.9/community >> /etc/apk/repositories && \ apk update && apk upgrade RUN apk --no-cache add ca-certificates wget && \ wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub && \ wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.29-r0/glibc-2.29-r0.apk && \ apk add glibc-2.29-r0.apk ENV JAVA_HOME=/usr/local/jdk1.8.0_211 ENV CLASSPATH=$JAVA_HOME/bin ENV PATH=.:$JAVA_HOME/bin:$PATH CMD ["java","-version"] ```
