【问题描述】：

我正在尝试使用 docker 运行部署，并且使用以下命令成功运行：

docker build -t romenigld/blog-prod .

但是当我尝试使用这个命令时：

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

我收到此错误：

【问题讨论】：

似乎很清楚，Beam 在运行时需要 c++ 库，并且它们要么在您构建的映像中找不到或不可用。考虑到 alpine 是一个最小的基础镜像，这并不奇怪。也许尝试不同的基础，例如 debian，或者找到一个将 c++ 库与其他构建依赖项一起安装到最终映像中的软件包...似乎 build-base 会包含它们...但是您正在创建一个干净的映像(COPY --from=build) 并且只复制您的构建输出...但不是所需的 c++ 库。

【解决方案1】：

根据您用于部署的内容，crypto（phoenix 使用加密）等软件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

【讨论】：

我添加了这个并且工作了：``` #prepare release image FROM alpine:3.14 AS app RUN apk upgrade --no-cache && \ apk add --no-cache postgresql-client bash openssl libgcc libstdc++ ncurses-libs ``` 感谢@daniel
我发现添加libstdc++ 对我特别有效（我已经安装了openssl 和ncurses-libs，但不需要其他任何东西）。有趣的是，直到今天这才对我造成错误——我猜某处发生了一些变化……无论如何，谢谢大家！
