CICD CodeDeployアーティファクトサイズリミットの対応(その２)

Last updated at Posted at 2021-07-30

#1. 概要
AWS CodePipelineのCodeCommitによるCICDのBlue/Greenを実装するには、Deployステージに渡されたアーティファクトのサイズ制限があり、前回の投稿ではS3のPipelineに変更と別のappspec.yml、taskdef.jsonだけを格納するCodeCommitリポジトリを作成の二つ対処方法を紹介した。

S3 Pipelineの対処方法には、作成されたCodeCommitタイプのPipelineのCloudFormationのソースファイルの変更作業が多いの短所があり、別のCodeCommitリポジトリの対処では改めてCodeCommitリポジトリの作成が必要もあるため、両対処とも少し手間が掛かる。

本文は、両対処方法の長所を連携し、S3バーケットを事前に作成し、Dockerファイルをこのバーケットにおいて置き、AWS::CodeBuild::Project段階まずCodeCommitリポジトリにある古いパッケージファイル（target/*.jarなど）cleanし、S3バーケットを利用してCodePipelineのSourceステージで作成されたアーティファクトのサイズの抑えることができ、別のCodeCommitリポジトリを作成しなくてもオリジナルのCodeCommitリポジトリのままでCICDを実現する方法を紹介する。

#2. 対処法
Step1：S3バーケットを作る。Dockerfileを格納する。
作成されたS3バーケットと格納されたDockerfile を下記の図をご参照ください。実際、このStepによりS3バーケットにDockerfileをアップロードしておけば、DockerfileをCodeCommitリポジトリに格納しなくてもCodeDeployを起動することが出来る。

FROM amazoncorretto:11-al2-jdk
EXPOSE 22
EXPOSE 80
EXPOSE 8080
RUN yum install -y iputils
RUN yum install -y net-tools
RUN yum install -y iputils
RUN yum -y install procps

RUN mkdir /usr/local/bin/api
RUN mkdir /usr/local/bin/batch
RUN mkdir /usr/local/bin/common
RUN mkdir /usr/local/bin/database
RUN mkdir /usr/local/bin/stubs
RUN mkdir /usr/local/bin/lib
ADD target/xxxxxxx_api-0.0.1-SNAPSHOT.jar /usr/local/bin/api/xxxxxxx_api-0.0.1-SNAPSHOT.jar
ENTRYPOINT ["java", "-jar", "/usr/local/bin/api/xxxxxxx_api-0.0.1-SNAPSHOT.jar"]

Step2：buildspec.ymlを編集する

Buildする際使用するDockerfileを、S3バーケットからコピーする、とDockerImageを作るにPathを“xxxxxxx-api/.”を指定することをご注意。
このbuildspec.ymlファイルをCodeBuildのProjectに埋め込み。

buildspec.yml
version: 0.2
env:
  parameter-store:
    DOCKER_USER: dockerhub-user
    DOCKER_TOKEN: dockerhub-token
phases:
  install:
    runtime-versions:
      java: corretto11
    commands:
      - mvn clean
      - aws s3 cp s3://xxx-dev-xxxx-s3-01/Dockerfile-xxxx-api-s3 .
  pre_build:
    commands:
      - echo Logging in to Amazon ECR...
      - $(aws ecr get-login --no-include-email)
      - REPOSITORY_URI=xxxxxxxxxxxx.dkr.ecr.ap-northeast-1.amazonaws.com/xxx-dev-xxxx-app-ecr
      - COMMIT_HASH=$(echo ${CODEBUILD_RESOLVED_SOURCE_VERSION} | cut -c 1-7)
      - IMAGE_TAG=${COMMIT_HAST:=latest}
      - echo Logging in to Docker Hub...
      - echo ${DOCKER_TOKEN} | docker login -u ${DOCKER_USER} --password-stdin
  build:
    commands:
      - echo Build started on `date`
      - mvn package --also-make --projects xxxxxxx-api -Dmaven.test.skip=true
      - echo Building the Docker image...
      # - docker build -t ${REPOSITORY_URI}:latest .
      - docker build -t $REPOSITORY_URI:latest xxxxxxx-api/. -f ./Dockerfile-xxxx-api-s3
      - docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:$IMAGE_TAG
  post_build:
    commands:
      - echo Build completed on `date`
      - echo Pushing the Docker images...
      # - docker push $REPOSITORY_URI:latest
      - docker push $REPOSITORY_URI:$IMAGE_TAG
      - echo Writing imageDetail json...
      - printf '{"ImageURI":"%s"}' $REPOSITORY_URI:$IMAGE_TAG > imageDetail.json
artifacts:
  files:
    - imageDetail.json

Step3：CodeCommitのリポジトリに応用開発のソースコード、及びappspec.yml、taskdef.jsonを格納する。下記図は例である。

Resources:
        - TargetService:
                Type: AWS::ECS::Service
                Properties:
                        TaskDefinition: "<TASK_DEFINITION>"
                        LoadBalancerInfo:
                                ContainerName: "xxx-dev-xxxx-app-container"
                                ContainerPort: "80"

4. 作成されたアーティファクトのサイズ

CodePipelineのSourceステージで作成されたアーティファクト（本文はAPPの名前にした）のサイズは、CloudFormationにて作成されたRsourceのS3で調べられる。本文の場合は609KBになった。

5. まとめ

CodePipelineのCodeCommitによるCICDのBlue/Greenを実装するには、現状のDeployステージに渡されたアーティファクトの3MBサイズ制限に対し、本文のS3バーケットを事前に作成、Dockerファイルをこのバーケットにおいて置き、CodeBuildの作成された中間JarファイルもS3バーケットを利用し、CodePipelineのSourceステージで作成されたアーティファクトのサイズの抑えることができた。この方法では、オリジナルのCodeCommitリポジトリままでCICDを実現することができる。
