docker run 加载共享库 libstdc++.so.6 和 libgcc_s.so.1 时出错

Question

我正在尝试使用 docker 运行部署，并且使用以下命令成功运行：

\n

docker build -t romenigld/blog-prod .

\n

但是当我尝试使用这个命令时：

\n

docker run --env-file .env -p 8080:4000 romenigld/blog-prod

\n

我收到此错误：

根据您用于部署的内容，像crypto（phoenix 使用 crypto）这样的包使用共享库来实现功能。对于高山，我通常安装：

RUN apk upgrade --no-cache && \
    apk add --no-cache postgresql-client bash openssl libgcc libstdc++ ncurses-libs
