ENV TZ=Asia/Shanghai

RUN ln -sf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# 3.将我们准备的fonts字体，拷贝到/usr/share/fonts下面
RUN mkdir -p /usr/share/fonts
RUN mkdir -p /usr/share/fonts/zh
COPY ./fonts /usr/share/fonts/zh
RUN cd /usr/share/fonts/zh && \
chmod -R 755 /usr/share/fonts && \
chmod -R 755 /usr/share/fonts/zh && \

# 4.安装字体
yum install mkfontscale fontconfig -y && \
mkfontscale && \
mkfontdir && \
fc-cache -fv
# 验证（这个构建好镜像后运行执行）
RUN fc-list :lang=zh

RUN mkdir -p /xxx

WORKDIR /xxx

ADD ./jar/xxx.jar ./

CMD java -Djava.security.egd=file:/dev/./urandom -jar -Duser.timezone=GMT+08 xxx.jar

或者

2. 在中文字体库安装目录下创建软链接：

$ ln -sf /usr/share/fonts/truetype/wqy/wqy-zenhei.ttf /usr/share/fonts/truetype/wqy-zenhei.ttf

FROM openjdk:8u332-oraclelinux7

#RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
#RUN apk add --update font-adobe-100dpi ttf-dejavu fontconfig

#在线安装字体
#RUN yum -y install  wget
#RUN wget -O /usr/share/fonts/simsun.ttf https://pfh-file-store.oss-cn-hangzhou.aliyuncs.com/simsun.ttf
#RUN fc-cache -vf
#RUN fc-list

#离线安装字体，先把离线字体文件加入dockerfile目录
COPY front/simsun.ttf /usr/share/fonts/simsun.ttf
#RUN mkfontscale
#RUN mkfontdir
RUN fc-cache -vf
RUN fc-list
