1. 准备中文字体
将所有需要添加的中文字体放进一个文件夹内，例如 fonts
2. 创建 Dockerfile 文件
Dockefile 文件与 fonts 文件夹放在同一目录下
# 使用 slim 版本的 jdk 17 镜像作为基础镜像
FROM openjdk:17-slim# 安装字体工具
RUN apt-get update && \apt-get install -y fontconfig && \rm -rf /var/lib/apt/lists/*# 创建存放字体的目录
RUN mkdir -p /usr/share/fonts/chinese# 将本地的字体文件复制到镜像中
COPY ./fonts /usr/share/fonts/chinese/# 更新字体缓存
RUN fc-cache -fv3. 构建镜像
docker build -t openjdk:17-jre-slim-chinese .

4. 确认字体安装
- 以新镜像启动容器
docker run -it --rm openjdk:17-jre-slim-chinese bash - 进入容器内部，查看字体
