创建rootfs
这张图在镜像基础介绍的时候已经被无数次看到了，rootfs是linux中重要的概念，而alpine中也有ADD rootfs.tar.xz这样一句，接下来我们将了解一下如何生成一个简单的rootfs
创建目录并进入
[root@kong ~]# mkdir rootfs
[root@kong ~]# cd rootfs/
[root@kong rootfs]#创建rootfs
执行如下语句
for module in `busybox --list-modules`
do
mkdir -p `dirname "$module"`
ln -sf /bin/busybox "$module"
done执行日志
[root@kong rootfs]# for module in `busybox --list-modules`
> do
> mkdir -p `dirname "$module"`
> ln -sf /bin/busybox "$module"
> done
[root@kong rootfs]#结果确认
[root@kong rootfs]# ls
bin linuxrc sbin usr
[root@kong rootfs]# find . -type d
.
./usr
./usr/bin
./usr/sbin
./sbin
./bin
[root@kong rootfs]#将busybox拷贝至新创建的./bin目录下
这样，上述命令的链接对象就存在了
[root@kong rootfs]# cp /usr/local/bin/busybox bin/
[root@kong rootfs]# ls -l bin/busybox
-rwxr-xr-x. 1 root root 1001112 May 25 05:27 bin/busybox
