Packer でイメージ作る最中に色々やってみる

Packer でイメージ作る最中に色々やってみる

日越してしまった・・・
昨日 の続きです。

nginx をイメージ作成の際に入れてみる

昨日作った example.json をいじってみます。

example.json
{
  "variables": {
    "aws_access_key": "",
    "aws_secret_key": ""
  },
  "builders": [{
    "type": "amazon-ebs",
    "access_key": "{{user `aws_access_key`}}",
    "secret_key": "{{user `aws_secret_key`}}",
    "region": "ap-northeast-1",
    "source_ami_filter": {
      "filters": {
        "virtualization-type": "hvm",
        "name": "ubuntu/images/*ubuntu-bionic-18.04-amd64-server-*",
        "root-device-type": "ebs"
      },
      "owners": ["099720109477"],
      "most_recent": true
    },
    "instance_type": "t3.micro",
    "ssh_username": "ubuntu",
    "ami_name": "packer-example {{timestamp}}"
  }],
  "provisioners": [
    {
      "type": "shell",
      "inline": [
        "sleep 30",
        "sudo apt-get update",
        "sudo apt-get install -y nginx"
      ]
    }
  ]
}

"name": "ubuntu/images/*ubuntu-bionic-18.04-amd64-server-*"

ちょっと、ubuntu を 16.04 から 18.04 にしてみました。

"instance_type": "t3.micro",

インスタンスタイプを新しいやつに・・・
⇒これは後で気づきましたが、課金かかるので、無料枠でやってる人は注意してください・・・

provisioners の項目が、今日の主体です。
シェルで、nginx をインストールしてます。
apt-get は sudo で動かさないと絶賛エラーを吐きます。

やってみた

> ./packer build -var 'aws_access_key=<access key>' -var 'aws_secret_key=<secret key>' example.json
amazon-ebs output will be in this color.

お、なんかできたっぽいですね。

nginx 接続確認

今作ったAMIを使用して、インスタンスを適当に上げてみましょう。
HTTP(80)が開いていればとりあえずアクセスできます。
で、やってみると・・・

Welcome to nginx.png

いけてますね。

まとめ

工夫すれば、オリジナルのイメージが簡単に作れることがわかりました。
結構さくさく作れますので、遊んでみてください。
くれぐれも課金には注意です（笑）
