一、下载文件

1. glibc
   下载地址
   glibc-2.33-r0.apk
   glibc-bin-2.33-r0.apk
   glibc-i18n-2.33-r0.apk

2. rsa
   sgerrand.rsa.pub

3. jre 1.8
   jre-8u201-linux-x64.tar.gz

二、精简JRE

1. 解压

tar -zxvf jre-8u201-linux-x64.tar.gz && mv jre1.8.0_201 jre

2. 精简

cd jre && rm -rf !(bin|lib|man) && \
rm -rf ./lib/plugin.jar \
./lib/ext/jfxrt.jar \
./bin/javaws \
./lib/javaws.jar \
./lib/desktop \
./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 \
./lib/locale/!(zh*)

3. 压缩

cd .. && tar zcvf jre.tar.gz jre/

三、Dockerfile

FROM alpine:3.15.11
WORKDIR /home

# 更换aline源、update
RUN echo "http://mirrors.aliyun.com/alpine/v3.15/community" > /etc/apk/repositories
RUN echo "http://mirrors.aliyun.com/alpine/v3.15/main" >> /etc/apk/repositories
RUN apk update && apk upgrade
RUN apk --no-cache add ca-certificates bash net-tools tzdata dmidecode
RUN rm -rf /var/cache/apk/*

# 安装glibc
COPY apk/glibc-2.33-r0.apk .
COPY apk/glibc-bin-2.33-r0.apk .
COPY apk/glibc-i18n-2.33-r0.apk .
COPY apk/sgerrand.rsa.pub /etc/apk/keys/sgerrand.rsa.pub
RUN apk add glibc-2.33-r0.apk glibc-bin-2.33-r0.apk glibc-i18n-2.33-r0.apk
RUN rm -rf *.apk

# 设置时间
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

# 解决中文乱码
RUN /usr/glibc-compat/bin/localedef -i en_US -f UTF-8 en_US.UTF-8
ENV LANG=en_US.UTF-8

# 安装jre
ADD jre.tar.gz .
ENV JAVA_HOME=/home/jre
ENV PATH=.:$PATH:$JAVA_HOME/bin

四、构建镜像

1. 文件目录
   
   

2. 构建镜像

docker build --tag java:1.8.0 .

五、容器测试

1. 进入容器

docker run -it --privileged -v /dev/mem:/dev/mem \
-v /sys/class/net/ens160/address:/home/address --rm java:1.8.0 bash

2. 测试
