「Packer」とは、TerraformでおなじみのHashiCorp社が出しているマシンイメージの作成ツールで、AWS、Azure、GCPなどマルチクラウドに対応している点が売りです。
AWSですと最近「EC2 Image Builder」というサービスが出ましたが、これに近いでしょう。
今回、Cloud9でPackerをインストール&実行して、AMIを作成してみました。
手順
1. Homebrewをインストール
以下リンク先の手順で一撃です。
「Cloud9にHomebrewをインストールする手順」
https://qiita.com/nasuvitz/items/5eec6ab9444cff8e9467
2. Packerをインストール
一撃です。
$ brew install packer
3. Packerテンプレートを書く
「Amazon AMI Builder」を見ながらテンプレートを作ります。
サンプルとして最新のAmazon Linux 2のAMIに、Apacheを追加したAMIを作成します。
AWS CLIでpackertestというプロファイルを作ってから、以下を作成します。
template.json
{
"builders": [
{
"profile": "packertest",
"type": "amazon-ebs",
"region": "ap-northeast-1",
"ami_name": "packer-test-amzn2",
"source_ami_filter": {
"filters": {
"name": "amzn2-ami-hvm-*-x86_64-gp2"
},
"owners": [
"137112412989"
],
"most_recent": true
},
"instance_type": "t3.micro",
"ssh_username": "ec2-user",
"launch_block_device_mappings": [
{
"delete_on_termination": true,
"device_name": "/dev/sda1",
"volume_size": 10,
"volume_type": "gp2"
}
]
}
],
"provisioners": [
{
"type": "shell",
"inline": [
"sudo yum -y install httpd",
"sudo systemctl start httpd && sudo systemctl enable httpd"
]
}
]
}
4. Packerテンプレートを実行
まずは正しく書けているか構文チェックします。
以下のように出力されればOKです。
$ packer validate template.json
Template validated successfully.
構文チェックが済んだら、AMIを作成します。
$ packer build template.json
amazon-ebs: output will be in this color.

実行中、Packer BuliderというEC2が起動し、このEC2のAMIが取られることで、新たなAMIが出来上がります。
出来上がったAMIを確認してみます。
Packerを使って、いとも簡単に、カスタムAMIを作成することができました。
サンプル実行時に気になるところ
-
一瞬、SSHが全開放になっている
- 「Authorizing access to port 22 from [0.0.0.0/0] in the temporary security groups」 という実行ログがあります。
- Packerのssh communicatorが、Packer BuliderのEC2に接続するようです。
-
一瞬、yumが競合している
- 「Another app is currently holding the yum lock; waiting for it to exit...」という実行ログがあります。
- Amazon Linux 2をAMIから初回起動するとき、最新セキュリティパッチが必ず当たるようになっていますので、その処理と競合したと思われます。
- OSの初回起動時のセキュリティパッチ適用処理の方が先に実行され、その後、Packerで定義した
provisionersの処理が実行されるようです。
まとめ
Terraformと同じく、AWS、Azure、GCPなどマルチクラウドに対応する際に、非常に有効なツールです。
AWSだけならEC2 Image Builderの選択肢もありますが、Packerは操作が簡単であり、AWS専用でも選択肢に入ります。
