docker - 错误重定位-未找到符号-构建docker-fpm-alpine镜像

Question

尝试创建图像(从有效的图像开始)，出现此错误，一直在搜索解决方案，但找不到合适的图像，我认为库有问题。不完全了解“未找到错误重定位符号”的含义，前面的步骤已成功运行，这是错误输出:

在Alpine Linux附带的最小(musl)系统C库(libc.so)和较典型的Linux发行版附带的较大的(GNU)libc之间，存在着有据可查的不兼容性。这些错误消息表明您正在经历类似的事情。

如果要安装142 MB的开发包，则实际上并不是在构建“微小的” Docker镜像，最简单的修复方法是将镜像更改为基于ubuntu:18.04而不是现在大概使用的Alpine基础。您最终的镜像最终将是200 MB，而不是200 MB，但是您不太可能会注意到任何实际差异。
