Docker 基本指令

在Docker啟動一個最小化的ubuntu/ CentOS/ Nginx/ MariaDB 環境 (創造貨櫃主機)

syntax: docker run --rm -it ubuntu

• --rm Automatically remove the container when it exits

• -it Instructs Docker to allocate a pseudo-TTY connected to the container’s stdin
  (pseudo-TTY = 虛擬終端機/ TTY = teletypes/ stdin = standard in)

• -d detached: Run container in background and print container ID

查詢IP location

hostname -i
cat /etc/hosts
docker exec [ID] hostname -i

Run a command in a running container

docker exec -it [container_ID] sh

Stop one or more running containers

syntax: docker stop [container_ID]

List containers

syntax: docker ps -a

• -a Show all containers (default shows just running)

apt-get 指令

apt-get upgrade
apt-get install all: 安裝全部套件

ifconfig
brctl show
