# docker run -it -d chusiang/takaojs1607 /bin/sh -c "while true; do echo "hi"; sleep 1; done"

​準備兩台終端機

# cd /
# mkdir /mydata
# echo "hello world" > hi.txt
# cat hi.txt

# docker run -it -v /mydata/data chusiang/takaojs1607 /bin/bash
# cd /
# cd data

#/bin/bash -c "while true; do echo "hi"; sleep 3 ; done"

# docker exec -it [容器名稱] bash

# docker run -it --name [容器名稱] --rm chusiang/takaojs1607 /bin/bash
# docker ps -a
# docker start [容器名稱]
# docker attach [容器名稱]

暫時離開容器：ctrl+p+q

# apt-get update
# apt-get install iputils-ping
如果上兩段程式有出現bug，使用：
# apt-get install --fix-missing

# apt install net-tools

# docker pull httpd
# docker images
將root路徑切換到mydata下執行：
# echo "this is a index webpage" > index.html
# echo "hi" > hi.htm
# docker run -itd --name mywebserver -p 8080:80 -v /mydata:/usr/local/apache2/htdocs httpd
