Mini Docker

This is my code for writing a mini docker with 自己动手写Docker.

Environment Setup

The code uses the following environment, you should be consistent with that. Because we are learning docker, this is the point. Don't waste your time. However, I refuse to use the low version of go. Although there would be some change, but it is easy to handle.

• Ubuntu 14.04
• Kernel: 3.13.0-83-generic
• Go: 1.19.1

Ubuntu IOS

Download from tuna:

wget https://mirrors.tuna.tsinghua.edu.cn/ubuntu-releases/trusty/ubuntu-14.04.6-server-amd64.iso

Change The Kernel

sudo apt-get update
sudo apt-get install linux-image-3.13.0-83-generic
sudo apt-get install linux-image-extra-$(uname -r)
sudo modprobe aufs

Change the configuration of the grub to start the corresponding kernel.

Download Go

wget https://golang.google.cn/dl/go1.19.1.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.19.1.linux-amd64.tar.gz

Next configure the environment.

export PATH=$PATH:/usr/local/go/bin

Other things

Due to the upgrade of the Go, when using cgo, the linker is a bit out-of-date. So we need use another tool:

sudo apt-get update
sudo apt-get install binutils-2.26
export PATH="/usr/lib/binutils-2.26/bin:$PATH"

At now, I have studied all the parts except the network. Well, it is a really wonderful tutorial. What I cannot build, I do not understand.
