## Sandbox

### 安裝

sudo apt install schroot debootstrap

#chroot用
sudo mkdir /var/chroot
sudo vim 

#設定檔
/etc/schroot/schroot.conf

[xenial]
description=Ubuntu xenial
type=directory
directory=/var/chroot/xenial
users=user1  #記得也要另外新增本機帳號sudo adduser user1
groups=sbuild
root-groups=root
preserve-environment=true

### 部屬

sudo debootstrap --arch <ARCH> <VERSION> <DIRECTORY> <MIRROR>

sudo debootstrap --variant=buildd --arch amd64 xenial /var/chroot/xenial http://archive.ubuntu.com/ubuntu/
or
sudo debootstrap --variant=buildd --arch i386 xenial /var/chroot/xenial http://archive.ubuntu.com/ubuntu/

### 進入系統

sudo schroot -c xenial

schroot -c xenial -u user1 (配合schroot.conf)

驗證
cat /etc/*-release
apt list --installed | grep php

sudo chroot /var/chroot/xenial

驗證
cat /etc/*-release
apt list --installed | grep php

apt update
apt --no-install-recommends install wget debconf devscripts gnupg nano vim

#### 部屬

sudo cp /etc/resolv.conf /var/chroot/xenial/etc/resolv.conf
sudo cp /etc/apt/sources.list /var/chroot/xenial/etc/apt/
sudo vim /var/chroot/xenial/etc/apt/sources.list

## Docker

### 安裝

sudo apt update

sudo apt upgrade

sudo apt-get install docker.io

### DOCKER Info

sudo docker version

sudo docker info

ifconfig docker0
    //ip -c a

### Docker Run

sudo docker run busybox echo "hello world"

sudo docker run --name test busybox ping localhost

sudo docker ps

### Web Demo

* -d：run指令的無數值參數，背景執行。
* --name web：run指令的文字參數，指定這個Container的名字為web。
* -p 8080:80：run指令的數值參數，把主機的8080通訊埠所有流量轉發到web這個Container的80通訊埠。

sudo docker run -d --name web -p 8080:80 joshhu/webdemo 

sudo docker ps -a

### Commit

sudo docker commit -m "myweb" {CONTAINER ID} myweb:v1

sudo docker run -d  -p 8080:80 myweb:v1 /start.sh

### Docker Remove

sudo docker ps -a

sudo docker images #查看系統目前有的images
 
sudo docker rm {CONTAINER ID} #刪除特定ID

### 其他

sudo docker stop {CONTAINER ID}
sudo docker start {CONTAINER ID}
sudo docker rm -f {CONTAINER ID}
sudo docker rm $(sudo docker ps -a -q) #全部刪除
sudo docker rmi {IMAGE ID}
