最初の設定

インスタンス内の Dibian を軽く見てみたが、
汎用のテンプレートなので、まっしろというか、 debootstrap 直後というか。。。

必要な設定を進める。

キーのコピー

ssh ログインのためのキーペアを作るのが本来だが、、、
admin のをコピーする（ぉぃぉぃ）

admin@ip-172-31-17-108:~$ tar cf - .ssh |(cd ~yasunari; sudo tar xvf -)
.ssh/
.ssh/authorized_keys
admin@ip-172-31-17-108:~$ sudo chown yasunari ~yasunari/.ssh ~yasunari/.ssh/*
admin@ip-172-31-17-108:~$ sudo ls -al ~yasunari/.ssh

ホスト名の変更

/etc/hostname の変更

yasunari@ip-172-31-17-108:~$ sudo -i
[sudo] password for yasunari:
root@ip-172-31-17-108:~# cd /etc/

-rw-r--r-- 1 root root 17 Dec 19 13:02 hostname.orig
root@ip-172-31-17-108:/etc#

/etc/hosts の変更

root@ip-172-31-17-108:/etc# vi hosts

/etc/hosts を変更しよとしたら、

# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
#     /etc/cloud/cloud.cfg or cloud-config from user-data
#

とのコメントが。
/etc/hosts を編集するだけではだめとのこと。
/etc/cloud/templates/hosts.tmpl を編集することにする。

root@ip-172-31-17-108:/etc# cd cloud/templates/
root@ip-172-31-17-108:/etc/cloud/templates# ls
chef_client.rb.tmpl  hosts.suse.tmpl       ntp.conf.sles.tmpl        sources.list.ubuntu.tmpl

hosts.redhat.tmpl    ntp.conf.rhel.tmpl    sources.list.debian.tmpl
root@ip-172-31-17-108:/etc/cloud/templates#

hosts.debian.tmpl を編集すれば良さそう

root@ip-172-31-17-108:/etc/cloud/templates# mv hosts.debian.tmpl{,.orig}
root@ip-172-31-17-108:/etc/cloud/templates# cp hosts.debian.tmpl{.orig,}
