Docker 套接字构建错误和 php-fpm 8.0 'sizeof' 对不完整类型 'struct cmsgcred' 的无效应用

Question

我有一个自定义 Docker 构建的 nginx 和 php-fpm，我很确定直到最近它还在工作。我现在在使用 8.0-fpm 时使用下面的 Docker 文件进行构建时出现上述错误，但使用 8.1.1-fpm-bullseye 时却没有，尽管在某些情况下使用 8.1.1 还存在一些其他问题PHP 代码（弃用和警告）。

任何有关优化构建的建议也将不胜感激。

如果我有一个帐户来存储私有图像，我还有一个关于将构建的图像保存到 Docker Hub 的问题。例如下面是 docker-compose.yml 文件的一个片段。我不太清楚是否可以绕过构建并仅使用我存储在 Docker Hub 帐户中的构建图像。似乎如果我注释掉构建行，那么它将访问 dockerhub 图像来构建容器，但我不清楚 Docker 文件中的其他一些命令是否（即入口点、作曲家安装等）在这种情况下执行。

我的目标是获得我认为“稳定”的图像，然后在 DockerHub 上提供这些图像，而不是每次都必须在新的 machine 上构建图像。另外，一旦我得到一个运行，mac 上的 M1 芯片可能会出现一些问题。

Answer 1

PHP 8.0.15 和 8.1.2 有一个错误，它会破坏编译 sockets 扩展。

您有两个选择：

跳过这个版本。
Apply a workaround 绕过错误并构建 sockets 扩展。
