[JAWS-UG CLI] Lambda:#21 Lambda関数の作成 (datadog-process-rds-metrics: Python版)

Lambdaのブループリントのうちdatadog-process-rds-metricsを利用して、Lambda関数を作成してみます。

今回は、KMSを使わないこととします。

前提条件

Lambdaへの権限

Lambdaに対してフル権限があること。

AWS CLI

以下のバージョンで動作確認済

• AWS CLI 1.11.28

コマンド

aws --version

結果(例):

  aws-cli/1.11.28 Python/2.7.10 Darwin/15.6.0 botocore/1.4.85

バージョンが古い場合は最新版に更新しましょう。

コマンド

sudo -H pip install -U awscli

IAM Role

'lambdaBasicExecution'ロールが存在すること。

変数の設定

IAM_ROLE_NAME='lambdaBasicExecution'

コマンド

aws iam get-role \
         --role-name ${IAM_ROLE_NAME}

結果(例):

  {
      "Role": {
        "AssumeRolePolicyDocument": {
            "Version": "2012-10-17",
            "Statement": [
                {
                    "Action": "sts:AssumeRole",
                    "Principal": {
                        "Service": "lambda.amazonaws.com"
                    },
                    "Effect": "Allow",
                    "Sid": ""
                }
            ]
        },
        "RoleId": "AROAXXXXXXXXXXXXXXXXX",
        "CreateDate": "2016-12-18T01:23:45Z",
        "RoleName": "lambdaBasicExecution",
        "Path": "/",
        "Arn": "arn:aws:iam::XXXXXXXXXXXX:role/lambdaBasicExecution"
      }
  }

IAMロールが存在しない場合、
http://qiita.com/tcsh/items/6353876a5c4fef63b4d8 の手順に従って作成し
てください。

0. 準備

0.1. リージョンの決定

変数の設定

export AWS_DEFAULT_REGION='ap-northeast-1'

0.2. 変数の確認

プロファイルが想定のものになっていることを確認します。

変数の確認

aws configure list

結果(例):

        Name                    Value             Type    Location
        ----                    -----             ----    --------
     profile       lambdaFull-prjz-mbp13        env    AWS_DEFAULT_PROFILE
  access_key     ****************XXXX shared-credentials-file
  secret_key     ****************XXXX shared-credentials-file
      region        ap-northeast-1        env    AWS_DEFAULT_REGION

1. 事前作業

1.1. IAM RoleのARN取得

コマンド

IAM_ROLE_ARN=$( \
        aws iam get-role \
          --role-name ${IAM_ROLE_NAME} \
          --query 'Role.Arn' \
          --output text \
) \
        && echo ${IAM_ROLE_ARN}

結果(例):

  arn:aws:iam::XXXXXXXXXXXX:role/lambdaBasicExecution

1.2. DatadogのAPIキーの設定

https://app.datadoghq.com/account/settings#api にアクセスします。

変数の設定

DD_API_KEY='<API KeysのKeyの値>'

New application keyに'lambda'と入力し、Create Application Keyボタンをクリックします。

Hashの値を変数に取り込みます。

変数の設定

DD_APP_KEY='<Application KeyのHashの値>'

1.3. Lambda関数名の決定

変数の設定

LAMBDA_FUNC_NAME="datadog_process_rds_metrics-$( date '+%Y%m%d' )" \
        && echo ${LAMBDA_FUNC_NAME}

同名のLambda関数の不存在確認

コマンド

aws lambda get-function \
        --function-name ${LAMBDA_FUNC_NAME}

結果(例):

  A client error (ResourceNotFoundException) occurred when calling the GetFunction operation: Function not found: arn:aws:lambda:ap-northeast-1:XXXXXXXXXXXX:function:datadog_process_rds_metrics-20161219

1.4. Lambda関数

変数の設定

FILE_LAMBDA_FUNC="${LAMBDA_FUNC_NAME}.py"
PY_FUNC_NAME='lambda_handler'

変数の確認

cat << ETX

          FILE_LAMBDA_FUNC: ${FILE_LAMBDA_FUNC}
