CodeDeployとCircleCIを利用したBlue/Greenデプロイメント

deployment:
  blue:
    branch: release/blue
    codedeploy:
      bg-deploy-app:         #CodeDeploy作成時のアプリケーション名
        application_root: /app  #appspec.ymlのパス
        revision_location:
          revision_type: S3   #リビジョンの保管場所(S3)
          s3_location:
            bucket: bg-deploy-app
            key_pattern: apps/{SHORT_COMMIT}  #S3バケットのキー名指定
        region: ap-northeast-1
        deployment_group: Blue             #デプロイメントグループ名
        deployment_config: CodeDeployDefault.AllAtOnce
  green:
    branch: release/green
    codedeploy:
      bg-deploy-app:
        application_root: /app
        revision_location:

CircleCIとAWS(CodeDeploy/S3)で作るCI環境

version: 0.0
os: linux # このあたりはお約束なのでそのまま記述すること

files:
# You can specify one or more mappings in the files section.
  - source: /
    destination: /home/ec2-user # 他が良ければ事前にユーザ名、ディレクトリは作成すること
hooks:
  BeforeInstall:
    - location: Scripts/BeforeInstall.sh      #下記デプロイ用シェル参照
  AfterInstall:
    - location: Scripts/AfterInstall.sh      #下記デプロイ用シェル参照
      timeout: 60
  ApplicationStart:
    - location: Scripts/ApplicationStart.sh   #下記デプロイ用シェル参照
      timeout: 60
  ValidateService:
    - location: Scripts/ValidateService.sh    #下記デプロイ用シェル参照
      timeout: 60

ステップ 2: サンプルのアプリケーションリビジョンを作成する

BeforeInstall.sh

#!/bin/bash
export FOLDER=/tmp/CodeDeployExample

if [ -d $FOLDER ]
then
 rm -rf $FOLDER
fi

mkdir -p $FOLDER

AfterInstall.sh

#!/bin/bash
cd /tmp/CodeDeployExample

echo "The AfterInstall deployment lifecycle event successfully completed." > after-install.txt

ApplicationStart.sh

#!/bin/bash
cd /tmp/CodeDeployExample

echo "The ApplicationStart deployment lifecycle event successfully completed." > application-start.txt

ValidateService.sh

#!/bin/bash
cd /tmp/CodeDeployExample

echo "The ValidateService deployment lifecycle event successfully completed." > validate-service.txt

unset FOLDER

実行権限付与

$ chmod +x ./Scripts/*
