docker with openSUSE 13.2 小記

最近覺得真的要撥一點時間學 docker 了...

OS 採用 openSUSE 13.2, 因為套件庫就內建 docker 了

OS: openSUSE 13.2

主要練習教材 《Docker —— 從入門到實踐­》正體中文版

docker 安裝

參考 https://docs.docker.com/installation/SUSE/ 安裝 docker

使用 zypper 指令安裝 docker

> sudo   zypper   in   docker

We trust you have received the usual lecture from the local System

Administrator. It usually boils down to these three things:

   #1) Respect the privacy of others.

   #2) Think before you type.

   #3) With great power comes great responsibility.

root's password: 輸入 root 密碼

6  新套件將被安裝.

Overall download size: 6.8 MiB. Already cached: 0 B  完成操作後，將增加 33.5 MiB 的使用。

要繼續嗎？ [y/n/? shows all options] (y):  輸入y

啟動 docker

> sudo  systemctl  start   docker

設定開機啟動 docker

> sudo  systemctl   enable   docker

Docker 官網有段文字要注意 ( 一般使用者如果要使用 docker, 要被加入到 docker 群組 )

The docker package creates a new group named docker. Users, other than root user, need to be part of this group in order to interact with the Docker daemon. You can add users with:

$ sudo   /usr/sbin/usermod   -a   -G   docker   <username>

驗證是否成功

> sudo   docker   run   --rm   -i   -t   opensuse    /bin/bash

目前是在 docker 內的 /bin/bash, 查看系統版本 ( 但是我也是 openSUSE 13.2 啊 ~~ )

bash-4.2# cat   /etc/*release

openSUSE 13.2 (x86_64)

VERSION = 13.2

CODENAME = Harlequin

# /etc/SuSE-release is deprecated and will be removed in the future, use /etc/os-release instead

NAME=openSUSE

VERSION="13.2 (Harlequin)"

VERSION_ID="13.2"

PRETTY_NAME="openSUSE 13.2 (Harlequin) (x86_64)"

ID=opensuse

ANSI_COLOR="0;32"

CPE_NAME="cpe:/o:opensuse:opensuse:13.2"

BUG_REPORT_URL="https://bugs.opensuse.org"

HOME_URL="https://opensuse.org/"

輸入 exit 離開

# exit

既然來了就測試一下別的 OS 吧 ^^

利用 docker pull 下載映像檔

> sudo   docker   pull   ubuntu:12.04

root's password:
