04 Alpine安装字体

alpine安装中文字体

1、alpine系统的字体软件是ttf-dejavu，执行命令apk add ttf-dejavu就可以安装了：

apk add ttf-dejavu

2、然后复制字体文件到/usr/share/fonts/目录下即可使用字体了：

# cd /usr/share/fonts/
# ls
chinese encodings ttf-dejavu

docker alpine 安装构建字体镜像

3、字体文件window系统和linux系统是通用的，因此可以直接在win10上复制需要的字体文件

Dockerfile中alpine安装中文字体

FROM openjdk:8u201-jdk-alpine3.9
#FROM openjdk:8u201-jre-alpine3.9
LABEL maintainer lijuzhang<lijuzhang@rlzbcy.com>

#*****时区设置*****
RUN echo http://mirrors.aliyun.com/alpine/v3.9/main > /etc/apk/repositories && \
    echo http://mirrors.aliyun.com/alpine/v3.9/community >> /etc/apk/repositories && \
    apk -U --no-cache add ca-certificates tzdata ttf-dejavu curl bash && \
    ln -sf /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

#*****添加中文字体*****
# alpine系统的字体软件是ttf-dejavu，执行命令apk add ttf-dejavu就可以安装，上面(时区设置部分)已经安装
COPY chinese /usr/share/fonts/

#*****拷贝应用*****
