Create Debian7 docker image

Docker importでイメージの作成をしてみた。debian7のvm内で作業した

dockerインストール

debian7ではapt-get install docker.ioでインストールできなかった…

https://docs.docker.com/installation/debian/のDebian Wheezy/Stable 7.x (64-bit) の方法で入れた

vagrant@packer-debian-7:~/debian-wheezy$ sudo echo "deb http://http.debian.net/debian wheezy-backports main" >> /etc/apt/sources.list
vagrant@packer-debian-7:~/debian-wheezy$ sudo apt-get update
vagrant@packer-debian-7:~/debian-wheezy$ sudo apt-get install -t wheezy-backports linux-image-amd64
vagrant@packer-debian-7:~/debian-wheezy$ curl -sSL https://get.docker.com/ | sh

debian7のイメージ作成

debootstrapを入れる

vagrant@packer-debian-7:~$ sudo apt-get install -y debootstrap

debianのベースシステムをインストール

vagrant@packer-debian-7:~$ mkdir debian-wheezy
vagrant@packer-debian-7:~$ sudo /usr/sbin/debootstrap wheezy ./debian-wheezy http://debian-mirror.sakura.ne.jp/debian/

chrootしてベースシステム確認

vagrant@packer-debian-7:~$ sudo chroot debian-wheezy /bin/bash
root@packer-debian-7:/# ls
bin   dev  home  lib64  mnt  proc  run   selinux  sys  usr
boot  etc  lib   media  opt  root  sbin  srv      tmp  var

よさげ

これを元にdockerイメージを作成

vagrant@packer-debian-7:~$ cd debian-wheezy/
vagrant@packer-debian-7:~/debian-wheezy$ sudo tar -c . | sudo docker import - debian-wheezy
c16645f2b6f50162d70acab19c7cf7f9988787455fed388763b41de78ca078c8

作成したイメージをdocker hubにアップロード

タグ追加

vagrant@packer-debian-7:~/debian-wheezy$ sudo docker tag c166 lorentzca/debian-wheezy-base:latest
vagrant@packer-debian-7:~/debian-wheezy$ sudo docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
debian-wheezy                  latest              c16645f2b6f5        9 minutes ago       218.5 MB
lorentzca/debian-wheezy-base   latest              c16645f2b6f5        9 minutes ago       218.5 MB

docker hubにプッシュ

vagrant@packer-debian-7:~/debian-wheezy$ sudo docker push lorentzca/debian-wheezy-base:latest

作成したイメージを使ってみる

新しくcoreosのvmを立ち上げて、使ってみる

検索するとちゃんとlorentzca/debian-wheezy-baseが表示されます。やったー!
