Docker install Debian

之前用docker安装magento2之后进行配置网站时，原环境是centos，我个人习惯于debian的环境配置，便直接pull了debian的最新版本开始环境配置：

## DOCKER IMAGE

for the example we can use Debian. Search in Docker hub the Image https://hub.docker.com/_/debian.

Now, download the image:

下载debian的docker最新镜像

docker pull debian

## CONTAINER

Now, we need to set up and run the image:

if went not download the image before, the debian image could be downloaded y create the Container.

pull下载完之后，启动镜像并进入容器内

docker run --name debian -e LANG=C.UTF-8 -it debian /bin/bash -l

with the command we obtain the bash shell section in the Container named to debian, with the hostname set to debian and locale to C.UTF-8.

## SETUP ENVIRONMENT

Now we can update and install some packages necessary:

更新软件包的列表，并安装本地环境包

apt update && apt upgrade --yes && apt install sudo locales --yes

configure datetime zone:

重新配置时区

dpkg-reconfigure tzdata

if we want to change the locale:

更改本地语言环境

rm -rf /var/lib/apt/lists/* && localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8 export LANG=en_US.utf8

## CREATE A USER

Now we need create a user into Container, it user in the Container should coincide with we user in the Host:

adduser

添加普通用户

user_name

将新建的用户赋予sudo权限

echo "user_name ALL=PASSWD: ALL" > /etc/sudoers.d/user_name

we user should coincide in the Host and Container since if we share volumes we will not have permission problems.

login and continue setting our Container.

su -

user_name

Now we can install some packages for make we development environment.

安装常用组件

sudo apt install curl nginx wget zip vim htop git build-essential cmake --yes

安装并户用ssh服务

sudo apt install openssh-client openssh-server --yes
/etc/init.d/ssh start

leave for Container CRTL-d until we finish at Host.

## CREATE IMAGE

after we have install all necessary in our Container we could save the Container as a new Image and remove the Container:

docker image ls

查看当前所有的镜像

for using username could have a user in Docker Hub and login in the Host using “docker login” command (read https://docs.docker.com/get-started/part2/#share-your-image).

将当前正在运行或是之前配置过的debian打包成新的镜像debiannewversion（任意取名）

docker commit debian debiannewversion

NOTE: from my username, docker commit debian username/debian:develop

将旧的原先下载的debian镜像删除（如果后续有用可以留着不删除）

docker rmi debian

## VOLUMES

使用新的镜像启动容器，并映射本地目录，以待之后创建网站时使用

docker run --name debiannew -v /var/www/html/debian:/var/www/html -it debiannewversion /bin/bash
