基于Alpine构建的java8 docker镜像运行后验证码不显示，并出现如下错误：

Error loading shared library libgcc_s.so.1: No such file or directory

是因为Alpine比较精简，默认没有 libgcc。安装上即可

apk add libgcc

完整的Dockerfile如下：

FROM alpine:3.21

ENV JAVA_HOME=/opt/java/openjdk
ENV PATH=$JAVA_HOME/bin:$PATH

# 默认utf-8编码及中国时区
ENV LANG='en_US.UTF-8' LANGUAGE='en_US:en' LC_ALL='en_US.UTF-8' TZ='Asia/Shanghai'

RUN set -eux; \
    ln -snf /usr/share/zoneinfo/${TZ} /etc/localtime && \
    echo ${TZ} > /etc/timezone && \
    echo https://mirrors.ustc.edu.cn/alpine/v3.21/main > /etc/apk/repositories && \
    echo https://mirrors.ustc.edu.cn/alpine/v3.21/community >> /etc/apk/repositories && \
    apk update && apk upgrade && \
    apk add --no-cache \
    # 解决验证码不显示问题
