docker java 最小镜像_docker构建JDK最小镜像

一、构建最小JDK

1、解压jre

# mv jre-8u181-linux-x64.tar.gz java1.8.tar.gz

# tar -xvcf jre-8u181-linux-x64.tar.gz

2、删除无用文件

# cd jre1.8.0_181/

# rm -rf COPYRIGHT LICENSE README release THIRDPARTYLICENSEREADME-JAVAFX.txt THIRDPARTYLICENSEREADME.txt Welcome.html

# rm -rf lib/plugin.jar \

lib/ext/jfxrt.jar \

bin/javaws \

lib/javaws.jar \

lib/desktop \

plugin \

lib/deploy* \

lib/*javafx* \

lib/*jfx* \

lib/amd64/libdecora_sse.so \

lib/amd64/libprism_*.so \

lib/amd64/libfxplugins.so \

lib/amd64/libglass.so \

lib/amd64/libgstreamer-lite.so \

lib/amd64/libjavafx*.so \

lib/amd64/libjfx*.so

3、重新打包

# tar acf java1.8.tar.gz java1.8

4、新建Dockerfile

# using alpine-glibc instead of alpine is mainly because JDK relies on glibc

FROM docker.io/jeanblanchard/alpine-glibc

# author

MAINTAINER simon

# A streamlined jre

ADD java1.8.tar.gz /usr/java/jdk/

# set env

ENV JAVA_HOME /usr/java/jdk

ENV PATH ${PATH}:${JAVA_HOME}/bin

# run container with base path:/opt

WORKDIR /opt

5、构建docker镜像

docker build -t simon/java8:1.0 .

这样构建的镜像大概120M左右
