使用docker搭建Linux 0.11 实验环境

使用docker搭建Linux 0.11 实验环境

对于学习linux内核的同学，Linux 0.11源码绝对是首选。但由于现在的硬件架构以及编译器的版本对于搭建Linux 0.11的实验环境会有一定的困难，因此本文目的是基于docker容器搭建一个纯净的Linux 0.11的环境。为你学习linux内核源码提供便利。
希望你的Linux内核学习之路能从这里开始。

获取源码

从github上获取Linux 0.11实验环境。

Note: Please ensure network available outside and then replace 'localhost' with the external ip or domain name.
      E.g. Virtualbox setting 'Network->Adapter2->Host-only Adapter' adds eth1. 'ifconfig eth1' give us the ip.
      Then 'echo $ip > .host_name' or 'echo $domain_name > .host_name'

Note: firefox, safari and edge work, but google chrome web browser is preferable.

ERR: No web browser found, are you running me in cloud? please open the 'Normal' url yourself.
