Amazon EC2 でインスタンスを作成する [aws]

Docs: Amazon EC2 (API Version 2010-08-31) を参考に、

OS: Ubuntu 10.04 LTS
Region: us-west-1
arch: 32-bit
root store: ebs
ami: ami-8c0c5cc9
の Micro Instance を作成します。

% ec2-add-keypair ec2-keypair > ~/.ssh/ec2-keypair.pem
% chmod 600 ~/.ssh/ec2-keypair.pem
% ec2-run-instances ami-8c0c5cc9 --instance-type t1.micro --region us-west-1 -k ec2-keypair
Client.InvalidKeyPair.NotFound: The key pair 'ec2-keypair' does not exist

とエラーになってしまいました。

% ec2-add-keypair --region us-west-1 ec2-keypair > ~/.ssh/ec2-keypair.pem
% ec2-run-instances ami-8c0c5cc9 --instance-type t1.micro --region us-west-1 -k ec2-keypair

でうまくいきました。

% ec2-describe-instances --region us-west-1

でインスタンスの状態が確認できます。

ssh で接続してみます。

% ec2-authorize --region us-west-1 default -p 22
GROUP default
PERMISSION default ALLOWS tcp 22 22 FROM CIDR 0.0.0.0/0
% ssh -i ~/.ssh/ec2-keypair.pem ubuntu@<external-host-name>

次に、今起動したマシンを自分用に保存するためにイメージを作成します。

% ec2-create-image --region us-west-1 i-907cf3d4 --name "Ubuntu 10.04 LTS"
IMAGE ami-875505c2


いったん終了し、先ほど作ったイメージで起動します。

% ec2-terminate-instances --region us-west-1 i-907cf3d4
INSTANCE i-907cf3d4 running shutting-down
% ec2-run-instances ami-875505c2 --instance-type t1.micro --region us-west-1 -k ec2-keypair
Client.InvalidAMIID.Unavailable: AMI 'ami-875505c2' is failed, and cannot be run

とエラーになってしまいました。

下記のように AMI 自体は存在しているようなのですが。。
% ec2-describe-images --region us-west-1 ami-875505c2

ec2-run-instances からやり直して、今度はスナップショットを作成し、スナップショットから AMI を作成し、その AMI からインスタンスを起動してみました。

% ec2-create-snapshot --region us-west-1 vol-d43acbbe

うまくいったようです。

しかし、ssh で接続してみるとタイムアウトしてしまいます。

Welcome to Ubuntu!


Ubuntu Official のインスタンスを起動する際に -b /dev/sda1=::false でボリュームを永続化して、AMI は Web GUI からではなく、ec2-create-image で作成しても ssh 接続できた。
