Docker构建java8最小docker镜像

一、现在java的JDK包

https://www.oracle.com/java/technologies/javase-server-jre8-downloads.html

二、解压文件

tar -xvzf jre-8u301-linux-x64.tar.gz

三、删除无用的文件

切换到解压的目录

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

四、重新打包

tar zcvf jre1.8.0_301.tar.gz *

五、编写Dockerfile文件

FROM docker.io/jeanblanchard/alpine-glibc

MAINTAINER wuzhiyong

ADD jre8.tar.gz /usr/java/jdk/

ENV JAVA_HOME /usr/java/jdk

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

WORKDIR /opt

六、构建镜像

docker build -t zgeo:java8 .

七、Tag镜像

docker tag zgeo:java8 <yourhost>/library/zgeo:java8

八、上传镜像

docker push <yourhost>/library/zgeo:java8
