linux-为什么docker无法在3.10之前的内核上运行？

Docker通常不会在3.10之前的Linux内核上运行. (在某些情况下,它也可以在3.8内核中运行).

旧内核中缺少的新内核中有哪些功能会阻止docker在其中运行？

最佳答案

A 3.10 Linux kernel is the minimum requirement for Docker. Kernels
older than 3.10 lack some of the features required to run Docker
containers. These older versions are known to have bugs which cause
data loss and frequently panic under certain conditions.

The latest minor version (3.x.y) of the 3.10 (or a newer maintained
version) Linux kernel is recommended. Keeping the kernel up to date
with the latest minor version will ensure critical kernel bugs get
fixed.
