问题描述

如何在没有特权模式的情况下更改 docker 容器内的 /proc/sys/kernel/core_pattern 文件?是否有任何标志要传递给 docker daemon 或 docker run 或任何与 Dockerfile 相关的东西?

推荐答案

内核不支持每个容器模式.有一个补丁可以解决这个问题，但不太可能很快发布.基本问题是核心模式支持管道到为此目的而产生的专用进程.但是产生它的代码还不知道如何处理容器.由于某种原因，需要目标文件的简化模式处理被认为是不可接受的.

The kernel does not support per-container patterns. There is a patch for this, but it is unlikely to go in any time soon. The basic problem is that core patterns support piping to a dedicated process which is spawned for this purpose. But the code spawning it does not know how to handle containers just yet. For some reason a simplified pattern handling which requires a target file was not deemed acceptable.
