基于OpenJDK/OracleJDK Alpine制作日常java基础镜像

Dockerfile内容如下：

FROM eclipse-temurin:8-jre-alpine

MAINTAINER devops(devops@example.com)

RUN apk update && apk --no-cache add tzdata ttf-dejavu fontconfig \
    && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \ 
    && echo "Asia/Shanghai" > /etc/timezone

ENV LANG=en_US.UTF-8 \
    LANGUAGE=en_US.UTF-8

RUN mkdir -p $JAVA_HOME/lib/fonts/fallback/ \
    && cd $JAVA_HOME/lib/fonts/fallback/ \
    && wget http://b.pig4cloud.com/SIMSUN.TTC

RUN mkdir -p /data/server
RUN addgroup -g 8080 -S app \
&& adduser app -h /data/server -D -G app -u 8080 -s /bin/sh
USER app
WORKDIR /data/server

解决docker alpine缺少字体的问题，Dockerfile内容如下：

FROM frolvlad/alpine-java:jre8-slim

MAINTAINER devops(devops@example.com)

RUN apk update && apk --no-cache add tzdata ttf-dejavu fontconfig \
    && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \ 
    && echo "Asia/Shanghai" > /etc/timezone

ENV LANG=en_US.UTF-8 \
    LANGUAGE=en_US.UTF-8

RUN mkdir -p $JAVA_HOME/lib/fonts/fallback/ \
    && cd $JAVA_HOME/lib/fonts/fallback/ \
    && wget http://b.pig4cloud.com/SIMSUN.TTC

RUN mkdir -p /data/server
RUN addgroup -g 8080 -S app \
&& adduser app -h /data/server -D -G app -u 8080 -s /bin/sh
USER app
WORKDIR /data/server

备注：增加时区、字体、非root用户
